The Future of Harley-Davidson...

With all these positives, what can be bad? Indian and Harley-Davidson.

World wide sales in the retro type cruiser are again starting to go down। Sales seem only to be strong in the USA. Indian Motorcycle has closed up shop, yet again, due to slow sales of the cruiser models. Harley-Davidson is still ignoring a huge market (younger crowd) and is still continuing to design models that appeal to fewer each year at prices even fewer can afford. With HD's 2004 "major" updates really being a "minor" change, has HD missed its mark again? Will Harley-Davidson be the next to go? (Sorry Harley riders)

Honda is now selling the Honda Rune, a style that is very impressive to see with your own eyes। This is a bike that looks like Harley-Davidson will make 20 years from now. Not only is the Honda Rune a big problem for HD, but the Vulcan 2000, Triumph Rocket III and even the Kawasaki/Suzuki Mean Streak are as well in the future design department. It used to be everyone copied HDs style, it was "the" cruiser look. Now you can have a sea of HD bikes, and if one of the above bikes shows up, it just gets noticed more.
So, what is Harley gonna do? They made the V-Rod. Beautiful lines, great engine, fuel injected, sporty looking... But... it doesn't sound like a Harley, doesn't look like a Harley, infact, it looks like a "Japanese" bike! The V-Rod as much an"outsider" to the HD community as a Buell, horrible shame that is too...

So, does Harley-Davidson keep making retro looking cruisers with very old and outdated technology so they have the look and sound? OR do they gamble on newer designs like the V-Rod? With an average consumer age of 46+, and thus you see the problems facing Harley-Davidson's future today.

Very Late 1980's --- The Motorcycle Rises Again!

It was bad near the end of the 1980's. Sales were just horrible from 10 years before. Those motorcycle dealerships who survived were in bad shape. But, there were a light at the end of the tunnel that only a few forsaw.

Two things most unexpected happened. The baby boomers came back to motorcycling and so did their kids. Seems they never forgot the fun and good times and with increased incomes could now purchase large and more expensive motorcycles. Their kids also wanted to get into the action and they did. Suddenly, things were looking up... but for how long?

First commercial products

In the decade from the late 1880s, dozens of designs and machines emerged, particularly in France, Germany and England, and soon spread to America.^[2] During this early period of motorcycle history, there were many manufacturers since bicycle makers were adapting their designs for the new internal combustion engine.

In 1894, the Hildebrand & Wolfmüller became the first motorcycle available to the public for purchase.^[3] However, only a few hundred examples of this motorcycle were ever built. Soon, as the engines became more powerful and designs outgrew the bicycle origins, the number of motorcycle-oriented producers increased.

The first known motorcycle in the United States was said to be brought to New York by a French circus performer, in 1895. It weighed about 200 lb (91 kg) and was capable of 40 mph (64 km/h) on a level surface.^[4] However, that same year, an inventor from the United States E.J. Pennington demonstrated a motorcycle of his own design in Milwaukee. Pennington claimed his machine was capable of a speed of 58 mph (93 km/h), and is credited with inventing the term "motor cycle" to describe his machine.^[5]

Motorcycle history

Motorcycle history begins in the second half of the 19th century. Motorcycles are descended from the "safety bicycle," a bicycle with front and rear wheels of the same size and a pedal crank mechanism to drive the rear wheel.^[1]

Despite some early landmarks in its development, motorcycles lack a rigid pedigree that can be traced back to a single idea or machine. Instead, the idea seems to have occurred to numerous engineers and inventors around Europe more-or-less simultaneously.

Off-Road abilities

Jeeps have always been known for their abilities off-road and are legendary for their off-road capabilities. ^[8]. Today, the Wrangler is the only light-duty vehicle offered in North America with solid axles front and rear. These axles are known for their durability due to their overall strength and lack of rubber boots to get torn on twigs and rocks. Solid-axled vehicles also generally articulate better, especially when traversing ruts. All Jeep Wranglers come standard with 4 wheel drive. Most Wranglers come with a Dana 35 rear axle and a Dana 30 up front. The upgraded Rubicon model of the Wrangler is equipped with lockers (either air or electric depending on year), Dana 44 axles front and rear with 4.11 gears, a 4:1 transfer case and heavy duty springs.

Another plus of solid axle vehicles is they tend to be easier and cheaper to "lift." This "lifting" increases the distance between the center of the axle hub and chassis of the vehicle. By increasing this distance, larger tires can be installed, which will increase the ground clearance of the Jeep, allowing it to traverse even larger and more difficult obstacles. Jeep is also known as a symbol of freedom because of the capacity of going almost everywhere. Many people equip theirs with roll-bars, extra lights, and a winch to pull the vehicle out from the mud or sand when stuck.

Useful features of the smaller Jeeps are their short wheelbases, narrow frames, and ample approach, breakover, and departure angles, allowing them to fit places where full-size trucks could never go. Jeeps also features a removable soft top and doors for days when the weather is nice. The Jeep Wrangler is the only utility vehicle that has a removable top and doors.

The M715

In 1965, Jeep developed the M715 1.25 ton army truck, which served extensively in Vietnam. Today it serves other countries, and is still being produced by Kia under license. The CJ series began back in 1945 with the CJ2A. The name CJ stands for "Civilian Jeep," a bit of trivia that is still argued over. These early Jeeps are commonly referred to as "flatfenders" because their front fenders were flat across the front, even with the grill. Yes, there was such a thing as a CJ-4, and in true Jeep form, there is only one, literally. There is only one 1951 CJ-4 prototype in existence, it's the "missing link" between the flatfendered CJ-2's and 3' and the round-fendered CJ-5.

The origins of the vehicle: the first jeeps

The first jeep prototype (the Bantam BRC) was built for the Department of the Army by American Bantam in Butler, Pennsylvania, ^[3]followed by two other competing prototypes produced by Ford and Willys-Overland. The American Bantam Car Company actually built and designed the vehicle that first met the Army's criteria, but its engine did not meet the Army's torque requirements. Plus, the Army felt that the company was too small to supply the number needed and it allowed Willys and Ford to make second attempts on their designs after seeing Bantam's vehicle in action.

Quantities (1,500) of each of the three models were then extensively field tested. During the bidding process for 16,000 "jeeps", Willys-Overland's chief engineer Delmar "Barney" Roos made extensive design changes to meet a revised weight specification (a maximum of 2,175 pounds, including oil and water). He was thus able to retain a powerful but comparatively heavy engine,and thus won the initial contract. Willys had designed what would become the standardized jeep, designating it a model MB military vehicle and building it at their plant in Toledo, Ohio.

Like American Bantam, Willys-Overland was a small company and, likewise, the military was concerned about their ability to produce large quantities of jeeps. The military was also concerned that Willys-Overland had only one manufacturing facility: something that would make the supply of jeeps more susceptible to sabotage or production stoppages.

Based on these two concerns, the U.S. government required that jeeps also be built by the Ford Motor Company, who designated the vehicle as model GPW (G = government vehicle, P designated the 80" wheelbase, and W = the Willys engine design). Willys and Ford, under the direction of Charles E. Sorensen (Vice-President of Ford during World War II), produced more than 600,000 jeeps. Cost per vehicle trended upwards as the war continued from the price under the first contract of a little less than $750. Besides just being a "truck" the jeep was used for many other purposes.

The jeep was widely copied around the world, including in France by Hotchkiss et Cie (after 1954, Hotchkiss manufactured Jeeps under license from Willys), and in Japan by Mitsubishi Motors. There were several versions created, including a railway jeep and an amphibious jeep. As part of the war effort, Jeeps were also supplied to the Soviet Red Army during World War II. During the jeep's service in Korea the name was referred to as "Just Enough Essential Parts" by the troops due to the very basic design.

The utilitarian good looks of the original Jeep have been hailed by industrial designers and museum curators alike. The Museum of Modern Art described the Jeep as a masterpiece of functionalist design, and has periodically exhibited the Jeep as part of its collection.^[4][5]

In the United States military, the jeep has been supplanted by a number of vehicles (e.g. Ford's M151 MUTT) of which the latest is the High Mobility Multipurpose Wheeled Vehicle (HMMWV or "Humvee").

Rudolf Diesel (1858 - 1913)

Rudolf Diesel was born in Paris in 1858. His parents were Bavarian immigrants. Rudolf Diesel was educated at Munich Polytechnic. After graduation he was employed as a refrigerator engineer. However, he true love lay in engine design. Rudolf Diesel designed many heat engines, including a solar-powered air engine. In 1893, he published a paper describing an engine with combustion within a cylinder, the internal combustion engine. In 1894, he filed for a patent for his new invention, dubbed the diesel engine. Rudolf Diesel was almost killed by his engine when it exploded. However, his engine was the first that proved that fuel could be ignited without a spark. He operated his first successful engine in 1897.
In 1898, Rudolf Diesel was granted patent #608,845 for an "internal combustion engine" the Diesel engine.
The diesel engines of today are refined and improved versions of Rudolf Diesel's original concept. They are often used in submarines, ships, locomotives, and large trucks and in electric generating plants.
Though best known for his invention of the pressure-ignited heat engine that bears his name, Rudolf Diesel was also a well-respected thermal engineer and a social theorist. Rudolf Diesel's inventions have three points in common: They relate to heat transference by natural physical processes or laws; they involve markedly creative mechanical design; and they were initially motivated by the inventor's concept of sociological needs. Rudolf Diesel originally conceived the diesel engine to enable independent craftsmen and artisans to compete with large industry.
At Augsburg, on August 10, 1893, Rudolf Diesel's prime model, a single 10-foot iron cylinder with a flywheel at its base, ran on its own power for the first time. Rudolf Diesel spent two more years making improvements and in 1896 demonstrated another model with the theoretical efficiency of 75 percent, in contrast to the ten percent efficiency of the steam engine. By 1898, Rudolf Diesel was a millionaire. His engines were used to power pipelines, electric and water plants, automobiles and trucks, and marine craft, and soon after were used in mines, oil fields, factories, and transoceanic shipping.

The History of Engines - How Engines Work

A steam engine is a device that converts the potential energy that exists as pressure in steam, and converts that to mechanical force. Early examples were the steam locomotive trains, and steamships that relied on these steam engines for movement. The Industrial Revolution came about primarily because of the steam engine. The thirty seconds or so required to develop pressure made steam less favored for automobiles, which are generally powered by internal combustion engines.
The first steam device was invented by Hero of Alexandria, a Greek, before 300BC, but never utilized as anything other than a toy. While designs had been created by varous people in the meanwhile, the first practical steam engine was patented by James Watt, a Scottish inventor, in 1769. Steam engines are of various types but most are reciprocal piston or turbine devices.
The strength of the steam engine for modern purposes is in its ability to convert raw heat into mechanical work. Unlike the internal combustion engine, the steam engine is not particular about the source of heat. Since the oxygen for combustion is unmetered, steam engines burn fuel cleanly and efficiently, with relatively little pollution.
One source of inefficiency is that the condenser causes losses by being somewhat hotter than the outside world. Thus any closed-cycle engine will always be somewhat less efficient than any open-cycle engine, because of condenser losses.
Most notably, without the use of a steam engine nuclear energy could not be harnessed for useful work, as a nuclear reactor does not directly generate either mechanical work or electrical energy - the reactor itself does nothing but sit there and get hot. It is the steam engine which converts that heat into useful work.*

The History of Airbags

Airbags are a type of automobile safety restraint like seatbelts. They are gas-inflated cushions built into the steering wheel, dashboard, door, roof, or seat of your car that use a crash sensor to trigger a rapid expansion to protect you from the impact of an accident.
Allen Breed - History of the AirbagAllen Breed was holding the patent (U.S. #5,071,161) to the only crash sensing technology available at the birth of the airbag industry. Breed invented a "sensor and safety system" in 1968, the world's first electromechanical automotive airbag system.
However, rudimental patents for airbags go back to the 1950s. Patent applications were submitted by German Walter Linderer and American John Hedrik as early as 1951.
Walter Linderer's airbag was based on a compressed air system, either released by bumper contact or by the driver. Later research during the sixties proved that compressed air could not blow the bags up fast enough. Linderer received German patent #896312.
John Hedrik received U.S. Patent #2,649,311 in 1953 for what he called a "safety cushion assembly for automotive vehicles."
Airbags IntroducedIn 1971, the Ford car company built an experimental airbag fleet. General Motors tested airbags on the 1973 model Chevrolet automobile that were only sold for government use. The 1973, Oldsmobile Toronado was the first car with a passenger air bag intended for sale to the public. General Motors later offered an option to the general public of driver side airbags in full-sized Oldsmobile's and Buick's in 1975 and 1976 respectively. Cadillacs were available with driver and passenger airbags options during those same years. Early airbags system had design issues resulting in fatalities caused solely by the airbags.
Airbags were offered once again as an option on the 1984 Ford Tempo automobile. By 1988, Chrysler became the first company to offer air bag restraint systems as standard equipment. In 1994, TRW began production of the first gas-inflated airbag. They are now mandatory in all cars since 1998.
Types of AirbagsThere are two types of airbags; frontal and the various types of side-impact airbags. Advanced frontal air bag systems automatically determine if and with what level of power the driver frontal air bag and the passenger frontal air bag will inflate. The appropriate level of power is based upon sensor inputs that can typically detect: 1) occupant size, 2) seat position, 3) seat belt use of the occupant, and 4) crash severity.
Side-impact air bags (SABs) are inflatable devices that are designed to help protect your head and/or chest in the event of a serious crash involving the side of your vehicle. There are three main types of SABs: chest (or torso) SABs, head SABs and head/chest combination (or "combo") SABs.

Garrett Morgan

Garrett Morgan was an inventor and businessman from Cleveland who is best known for inventing a device called the Morgan safety hood and smoke protector in 1914.
Garrett Morgan - BiographyThe son of former slaves, Garrett Morgan was born in Paris, Kentucky on March 4, 1877. His early childhood was spent attending school and working on the family farm with his brothers and sisters. While still a teenager, he left Kentucky and moved north to Cincinnati, Ohio in search of opportunity.
Although Garrett Morgan's formal education never took him beyond elementary school, he hired a tutor while living in Cincinnati and continued his studies in English grammar. In 1895, Morgan moved to Cleveland, Ohio, where he went to work as a sewing machine repair man for a clothing manufacturer. News of his proficiency for fixing things and experimenting traveled fast and led to numerous job offers from various manufacturing firms in the Cleveland area.
In 1907, the inventor opened his own sewing equipment and repair shop. It was the first of several businesses he would establish. In 1909, he expanded the enterprise to include a tailoring shop that employed 32 employees. The new company turned out coats, suits and dresses, all sewn with equipment that Garrett Morgan himself had made.
In 1920, Garrett Morgan moved into the newspaper business when he established the Cleveland Call. As the years went on, he became a prosperous and widely respected business man, and he was able to purchase a home and an automobile. Indeed it was Morgan's experience while driving along the streets of Cleveland that inspired him to invent an improvement to traffic signals.

Mary Anderson

Prior to the manufacture of Henry Ford's Model A, Mary Anderson was granted her first patent for a window cleaning device in November of 1903. Her invention could clean snow, rain, or sleet from a windshield by using a handle inside the car. Her goal was to improve driver vision during stormy weather - Mary Anderson invented the windshield wiper.
During a trip to New York City, Mary Anderson noticed that streetcar drivers had to open the windows of their cars when it rained in order to see, as a solution she invented a swinging arm device with a rubber blade that was operated by the driver from within the vehicle via a lever. The windsheld wipers became standard equipment on all American cars by 1916.
zSB(3,3)
The automobile gave women ample opportunity for invention. In 1923, of the 345 inventions listed under "Transportation" in the Women's Bureau Bulletin No.28, about half were related to automobiles and another 25 concerned traffic signals and turn indicators. Among these inventions -- a carburetor, a clutch mechanism, an electric engine starter, and a starting mechanism.
During the 1930s, Helen Blair Bartlett developed new insulations for spark plugs. A geologist by training, her knowledge of petrology and mineralogy was critical in the development of innovative uses of alumina ceramics.
Another woman inventor named Charlotte Bridgwood invented the first automatic windshield wiper. Charlotte Bridgwood, president of the Bridgwood Manufacturing Company of New York, patented her electric roller-based windshield wiper called the "Storm Windshield Cleaner" in 1917. However, her product was not a commercial success.

Vincent Bendix 1882-1945

Vincent Bendix was born in Moline, Illinois on August 12, 1882. In 1901, Vincent Bendix was hired by Glenn Curtiss to work on the Torpedo motorcycle, and later in 1904, Bendix worked as general sales manager for Holsman Automobile Company. As a consequence, Vincent Bendix learned all about the internal combustion engine and decided make a career in automobile design.
Between 1907 and 1909, Vincent Bendix designed the Bendix Motor Buggy and started an automobile firm. Seven thousand Bendix buggies were sold, however, Bendix had to declare bankruptcy and went back to work selling Cadillacs. In 1910, Vincent Bendix patented the Bendix drive for electric starters, an improvement to the hand cranked starters of the time. The first automobile to use the Bendix starter drive was the 1914 Chevrolet "Baby Grand". The Bendix starter became a standard in all cars produced in the United States.
Fortunes improved for the inventor and in 1923, Vincent Bendix bought the patent rights to Perrot brakes and controls and started the Bendix Brake Company. Bendix turned his research towards creating a more efficient braking system for automobiles and created the first four wheel automotive brake system
In 1929, Vincent Bendix started the Bendix Aviation Corporation and later invented the pressure carburetor for aircraft engines. By 1938, Bendix's pressure carburetor was installed on almost every American aircraft.
In 1931, Bendix established the Transcontinental Bendix Air Race. In 1942, Vincent Bendix started his last enterprise, Bendix Helicopters, Inc. (1942).

History of the Harley Davidson Motorcycle

Many of the nineteenth century inventors who worked on early motorcycles often moved on to other inventions. Daimler and Roper, for example, both went on to develop automobiles. However, inventors Harley and the Davidsons developed motorcycles and their business competitors were other new start-up companies such as Excelsior, Indian, Pierce, Merkel, Schickel and Thor.
In 1903, William Harley and his friends Arthur and Walter Davidson launched the Harley-Davidson Motor Company. The bike had a quality engine, so it could prove itself in races, however, the company planned to manufacture it as a transport vehicle. Merchant, C. H. Lange, sold the first officially distributed Harley-Davidson in Chicago.

The Duryea Brothers

America's first gasoline powered commercial car manufacturers were two brothers, Charles Duryea (1861-1938) and Frank Duryea. The brothers were bicycle makers who became interested in gasoline engines and automobiles. On September 20 1893, their first automobile was constructed and successfully tested on the public streets of Springfield, Massachusetts. Charles Duryea founded the Duryea Motor Wagon Company in 1896, the first company to manufacture and sell gasoline powered vehicles. By 1896, the company had sold thirteen cars of the model Duryea, an expensive limousine, which remained in production into the 1920s.
America's First Automobile Race At 8:55 a.m. on November 28, 1895, six motor cars left Chicago's Jackson Park for a 54 mile race to Evanston, Illinois and back through the snow. Number 5, piloted by inventor J. Frank Duryea, won the race in just over 10 hours at an average speed of about 7.3 miles per hour. The winner earned $2,000, the enthusiast who named the horseless vehicles "motorcycles" won $500, and the Chicago Times-Herald, sponsor of the race, declared, "Persons who are inclined to decry the development of the horseless carriage will be forced to recognize it as an admitted mechanical achievement, highly adapted to some of the most urgent needs of our civilization."
America's First Recorded Automobile Accident In March 1896, Charles and Frank Duryea of Springfield, Mass., offer the first commercial automobile: the Duryea motor wagon. Two months later, New York City motorist Henry Wells hits a bicyclist with his new Duryea. The rider suffers a broken leg, Wells spends a night in jail and the nation's first traffic accident is recorded."

The Importance of Gottlieb Daimler

In 1885, Gottlieb Daimler (together with his design partner Wilhelm Maybach) took Otto's internal combustion engine a step further and patented what is generally recognized as the prototype of the modern gas engine. Daimler's connection to Otto was a direct one; Daimler worked as technical director of Deutz Gasmotorenfabrik, which Nikolaus Otto co-owned in 1872. There is some controversy as to who built the first motorcycle Otto or Daimler.
The 1885 Daimler-Maybach engine was small, lightweight, fast, used a gasoline-injected carburetor, and had a vertical cylinder. The size, speed, and efficiency of the engine allowed for a revolution in car design. On March 8, 1886, Daimler took a stagecoach and adapted it to hold his engine, thereby designing the world's first four-wheeled automobile. Daimler is considered the first inventor to have invented a practical internal-combustion engine.
In 1889, Daimler invented a V-slanted two cylinder, four-stroke engine with mushroom-shaped valves. Just like Otto's 1876 engine, Daimler's new engine set the basis for all car engines going forward. Also in 1889, Daimler and Maybach built their first automobile from the ground up, they did not adapt another purpose vehicle as they had always been done previously. The new Daimler automobile had a four-speed transmission and obtained speeds of 10 mph.
Daimler founded the Daimler Motoren-Gesellschaft in 1890 to manufacture his designs. Eleven years later, Wilhelm Maybach designed the Mercedes automobile. (Learn more about Gottlieb Daimler & Wilhelm Maybach)
*If Siegfried Marcus built his second car in 1875 and it was as claimed, it would have been the first vehicle powered by a four-cycle engine and the first to use gasoline as a fuel, the first having a carburetor for a gasoline engine and the first having a magneto ignition. However, the only existing evidence indicates that the vehicle was built circa 1888/89 - too late to be first.

The History of the Automobile

The very first self-powered road vehicles were powered by steam engines and by that definition Nicolas Joseph Cugnot of France built the first automobile in 1769 - recognized by the British Royal Automobile Club and the Automobile Club de France as being the first. So why do so many history books say that the automobile was invented by either Gottlieb Daimler or Karl Benz? It is because both Daimler and Benz invented highly successful and practical gasoline-powered vehicles that ushered in the age of modern automobiles. Daimler and Benz invented cars that looked and worked like the cars we use today. However, it is unfair to say that either man invented "the" automobile.

The History of the Automobile

The automobile as we know it was not invented in a single day by a single inventor. The history of the automobile reflects an evolution that took place worldwide. It is estimated that over 100,000 patents created the modern automobile. However, we can point to the many firsts that occurred along the way. Starting with the first theoretical plans for a motor vehicle that had been drawn up by both Leonardo da Vinci and Isaac Newton.
In 1769, the very first self-propelled road vehicle was a military tractor invented by French engineer and mechanic, Nicolas Joseph Cugnot (1725 - 1804). Cugnot used a steam engine to power his vehicle, built under his instructions at the Paris Arsenal by mechanic Brezin. It was used by the French Army to haul artillery at a whopping speed of 2 1/2 mph on only three wheels. The vehicle had to stop every ten to fifteen minutes to build up steam power. The steam engine and boiler were separate from the rest of the vehicle and placed in the front (see engraving above). The following year (1770), Cugnot built a steam-powered tricycle that carried four passengers.
zSB(3,3)
In 1771, Cugnot drove one of his road vehicles into a stone wall, making Cugnot the first person to get into a motor vehicle accident. This was the beginning of bad luck for the inventor. After one of Cugnot's patrons died and the other was exiled, the money for Cugnot's road vehicle experiments ended.
Steam engines powered cars by burning fuel that heated water in a boiler, creating steam that expanded and pushed pistons that turned the crankshaft, which then turned the wheels. During the early history of self-propelled vehicles - both road and railroad vehicles were being developed with steam engines. (Cugnot also designed two steam locomotives with engines that never worked well.) Steam engines added so much weight to a vehicle that they proved a poor design for road vehicles; however, steam engines were very successfully used in locomotives. Historians, who accept that early steam-powered road vehicles were automobiles, feel that Nicolas Cugnot was the inventor of the first automobile.

Automobile History

By definition an automobile or car is a wheeled vehicle that carries its own motor and transports passengers. The automobile as we know it was not invented in a single day by a single inventor. The history of the automobile reflects an evolution that took place worldwide.
It is estimated that over 100,000 patents created the modern automobile. You can point to the many firsts that occurred along the way to producing the modern car; and with that goal in mind, highlighted below are articles, biographies, timelines, and photo galleries related to the history of the automobile and its many inventors

Applications

Internal combustion engines are most commonly used for mobile propulsion in vehicles and portable machinery. In mobile equipment, internal combustion is advantageous since it can provide high power-to-weight ratios together with excellent fuel energy density. Generally using fossil fuel (mainly petroleum), these engines have appeared in transport in almost all vehicles (automobiles, trucks, motorcycles, boats, and in a wide variety of aircraft and locomotives).
Internal combustion engines appear in the form of gas turbines as well where a very high power is required, such as in jet aircraft, helicopters, and large ships. They are also frequently used for electric generators and by industry.

Rocket engine

A rocket engine or simply rocket is a jet engine[1] that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist. Somewhat confusingly a vehicle propelled by a rocket engine is often termed a rocket also.

Internal combustion engine

The internal combustion engine is an engine in which the combustion of a fuel occurs with an oxidiser (usually air) in a combustion chamber. In an internal combustion engine the expansion of the high temperature and pressure gases, that are produced by the combustion, directly apply force to a movable component of the engine, such as the pistons or turbine blades and by moving it over a distance, generate useful mechanical energy.[1][2][3][4]
The term internal combustion engine usually refers to an engine in which combustion is intermittent, such as the more familiar four-stroke and two-stroke piston engines, along with variants, such as the Wankel rotary engine. A second class of internal combustion engines use continuous combustion: gas turbines, jet engines and most rocket engines, each of which are internal combustion engines on the same principle as previously described.[1][2][3][4]
The internal combustion engine (or ICE) is quite different from external combustion engines, such as steam or Stirling engines, in which the energy is delivered to a working fluid not consisting of, mixed with or contaminated by combustion products. Working fluids can be air, hot water, pressurised water or even liquid sodium, heated in some kind of boiler by fossil fuel, wood-burning, nuclear, solar etc.
A large number of different designs for ICEs have been developed and built, with a variety of different strengths and weaknesses. While there have been and still are many stationary applications, the real strength of internal combustion engines is in mobile applications and they completely dominate as a power supply for cars, aircraft, and boats, from the smallest to the biggest. Only for hand-held power tools do they share part of the market with battery powered devices. Powered by an energy-dense fuel (nearly always liquid, derived from fossil fuels) the ICE delivers an excellent power-to-weight ratio with very few safety or other disadvantages

Automotive design

Automotive design is the profession involved in the development of the appearance, and to some extent the ergonomics, of motor vehicles or more specifically road vehicles. This most commonly refers to automobiles but also refers to motorcycles, trucks, buses, coaches, and vans. The functional design and development of a modern motor vehicle is typically done by a large team from many different disciplines included in automotive engineers. Automotive design in this context is primarily concerned with developing the visual appearance or aesthetics of the vehicle, though it is also involved in the creation of the product concept. Automotive design is practiced by designers who usually have an art background and a degree in industrial design or transportation design.

Gas turbine

In the 1950s there was a brief interest in using gas turbine engines and several makers including Rover and Chrysler produced prototypes. In spite of the power units being very compact, high fuel consumption, severe delay in throttle response, and lack of engine braking meant no cars reached production

Air

A compressed air car is an alternative fuel car that uses a motor powered by compressed air. The car can be powered solely by air, or by air combined (as in a hybrid electric vehicle) with gasoline/diesel/ethanol or electric plant and regenerative braking. Instead of mixing fuel with air and burning it to drive pistons with hot expanding gases; compressed air cars use the expansion of compressed air to drive their pistons. Several prototypes are available already and scheduled for worldwide sale by the end of 2008, though this has not happened as of January 2009. Companies releasing this type of car include Tata Motors and Motor Development International (MDI).

Steam

Steam power, usually using an oil- or gas-heated boiler, was also in use until the 1930s but had the major disadvantage of being unable to power the car until boiler pressure was available (although the newer models could achieve this in well under a minute). It has the advantage of being able to produce very low emissions as the combustion process can be carefully controlled. Its disadvantages include poor heat efficiency and extensive requirements for electric auxiliaries.[23].

Electric

The first electric cars were built around 1832, well before internal combustion powered cars appeared.[21] For a period of time electrics were considered superior due to the silent nature of electric motors compared to the very loud noise of the gasoline engine. This advantage was removed with Hiram Percy Maxim's invention of the muffler in 1897. Thereafter internal combustion powered cars had two critical advantages: 1) long range and 2) high specific energy (far lower weight of petrol fuel versus weight of batteries). The building of battery electric vehicles that could rival internal combustion models had to wait for the introduction of modern semiconductor controls and improved batteries. Because they can deliver a high torque at low revolutions electric cars do not require such a complex drive train and transmission as internal combustion powered cars. Some post-2000 electric car designs such as the Venturi Fétish are able to accelerate from 0-60 mph (96 km/h) in 4.0 seconds with a top speed around 130 mph (210 km/h). Others have a range of 250 miles (400 km) on the United States Environmental Protection Agency‎ (EPA) highway cycle requiring 3-1/2 hours to completely charge.[22] Equivalent fuel efficiency to internal combustion is not well defined but some press reports give it at around 135 miles per US gallon (1.74 L/100 km; 162 mpg-imp).

Biofuels

Ethanol, other alcohol fuels (biobutanol) and biogasoline have widespread use an automotive fuel. Most alcohols have less energy per liter than gasoline and are usually blended with gasoline. Alcohols are used for a variety of reasons - to increase octane, to improve emissions, and as an alternative to petroleum based fuel, since they can be made from agricultural crops. Brazil's ethanol program provides about 20% of the nation's automotive fuel needs, as a result of the mandatory use of E25 blend of gasoline throughout the country, 3 million cars that operate on pure ethanol, and 6 million dual or flexible-fuel vehicles sold since 2003.[17] that run on any mix of ethanol and gasoline. The commercial success of "flex" vehicles, as they are popularly known, have allowed sugarcane based ethanol fuel to achieve a 50% market share of the gasoline market by April 2008.[18][19][20]

Gasoline

Gasoline engines have the advantage over diesel in being lighter and able to work at higher rotational speeds and they are the usual choice for fitting in high-performance sports cars. Continuous development of gasoline engines for over a hundred years has produced improvements in efficiency and reduced pollution. The carburetor was used on nearly all road car engines until the 1980s but it was long realised better control of the fuel/air mixture could be achieved with fuel injection. Indirect fuel injection was first used in aircraft engines from 1909, in racing car engines from the 1930s, and road cars from the late 1950s.[16] Gasoline Direct Injection (GDI) is now starting to appear in production vehicles such as the 2007 (Mark II) BMW Mini. Exhaust gases are also cleaned up by fitting a catalytic converter into the exhaust system. Clean air legislation in many of the car industries most important markets has made both catalysts and fuel injection virtually universal fittings. Most modern gasoline engines also are capable of running with up to 15% ethanol mixed into the gasoline - older vehicles may have seals and hoses that can be harmed by ethanol. With a small amount of redesign, gasoline-powered vehicles can run on ethanol concentrations as high as 85%. 100% ethanol is used in some parts of the world (such as Brazil), but vehicles must be started on pure gasoline and switched over to ethanol once the engine is running. Most gasoline engined cars can also run on LPG with the addition of an LPG tank for fuel storage and carburettor modifications to add an LPG mixer. LPG produces fewer toxic emissions and is a popular fuel for fork-lift trucks that have to operate inside buildings.

Fuel and propulsion technologies

Most automobiles in use today are propelled by gasoline (also known as petrol) or diesel internal combustion engines, which are known to cause air pollution and are also blamed for contributing to climate change and global warming.[14] Increasing costs of oil-based fuels, tightening environmental laws and restrictions on greenhouse gas emissions are propelling work on alternative power systems for automobiles. Efforts to improve or replace existing technologies include the development of hybrid vehicles, and electric and hydrogen vehicles which do not release pollution into the air.

Automobile

An automobile or motor car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.[1] However, the term automobile is far from precise, because there are many types of vehicles that do similar tasks.
As of 2002, there were 590 million passenger cars worldwide (roughly one car per eleven people).[2] Around the world, there were about 806 million cars and light trucks on the road in 2007; they burn over 260 billion gallons of gasoline and diesel fuel yearly. The numbers are increasing rapidly, especially in China and India.[3]

Diesel combustion exhaust is a major source of atmospheric soot and fine particles, which is a fraction of air pollution implicated in human heart and lung damage. Diesel exhaust also contains nanoparticles. While the study of nanoparticles and nanotoxicology is still in its infancy, and the full health effects from nanoparticles produced by all types of diesel are unknown. At least one study has observed that short term exposure to diesel exhaust does not result in adverse extra-pulmonary effects, effects that are often correlated with an increase in cardiovascular disease.[24] Long term effects still need to be clarified, as well as the effects on susceptible groups of people with cardiopulmonary diseases. It should be noted that the types and quantities of nanoparticles can vary according to operating temperatures and pressures, presence of an open flame, fundamental fuel type and fuel mixture, and even atmospheric mixtures. As such, the resulting types of nanoparticles from different engine technologies and even different fuels are not necessarily comparable. In general, the usage of biodiesel and biodiesel blends results in decreased pollution. One study has shown that the volatile component of 95% of diesel nanoparticles is unburned lubricating oil.[25]Diesel combustion exhaust is a major source of atmospheric soot and fine particles, which is a fraction of air pollution implicated in human heart and lung damage.

Automobile History

By definition an automobile or car is a wheeled vehicle that carries its own motor and transports passengers. The automobile as we know it was not invented in a single day by a single inventor. The history of the automobile reflects an evolution that took place worldwide.
It is estimated that over 100,000 patents created the modern automobile. You can point to the many firsts that occurred along the way to producing the modern car; and with that goal in mind, highlighted below are articles, biographies, timelines, and photo galleries related to the history of the automobile and its many inventors.
