Air

A compressed air car is an alternative fuel car that uses a motor powered by car. 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 regenration. Instead of mixing fuel with air and burning it to drive pistons with hot expanding gases; compressed air cars use the expansion motors and motor development 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 (MDI).


Gas turbine

In the 1950s there was a brief interest in using gas trubine engines and several makers including Rover and Chyrsler 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.


Rotary (Wankel) engines

Rotary wankel engines were introduced into road cars by NSU with the Ro 80 and later were seen in the Citreon GS Birtor and several Mazda models. In spite of their impressive smoothness, poor reliability and fuel economy led to them largely disappearing. Mazda, beginning with the R100 then RX-2, has continued research on these engines, overcoming most of the earlier problems with theRX-7 and RX-9.


Rocket and jet cars

A rocket car holds the record in drag racing. However, the fastest of those cars are used to set the Land Speed Record, and are propelled by propulsive jets emitted from rocket turbojet, or more recently and most successfully turbofan engines. TheThrustSSc car using two Rolls-Royce Spey turbofans withreheat was able to exceed the speed of sound at ground level in 1997.


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. 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.


Petroleum fuels

Diesel-engined cars have long been popular in Europe with the first models being introduced as early as 1922 by Peugot and the first production car, Mercedes-Benz 260 D in 1936 by Mercedes-Benz. The main benefit of diesel engines is a 50% fuel burn efficiency compared with 27% in the best gasoline engines. A down-side of the Diesel engine is that better filters are required to reduce the presence in the exhaust gases of fine soot particulates called diesel particulate matter. Manufacturers are now starting to fit diesel particulate filters to remove the soot. Many diesel-powered cars can run with little or no modifications on 100% biodiesel and combinations of other organic oils.


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 1950. 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 asBrazil), 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 fo fork lift trucks that have to operate inside buildings.




Production

The large-scale, production line manufacturing of affordable automobiles was debuted by ransom olds at his oldmobile factory in 1902. This concept was greatly expanded by Henru Ford, beginning in 1914.


As a result, Ford's cars came off the line in fifteen minute intervals, much faster than previous methods, increasing productivity eight fold (requiring 12.5 man-hours before, 1 hour 33 minutes after), while using less manpower. It was so successful, paint became a bottleneck. Only Japan black would dry fast enough, forcing the company to drop the variety of colors available before 1914, until fast-drying Duco Lacquer was developed in 1926. This is the source of Ford's apocryphal remark, "any color as long as it's black".In 1914, an assembly line worker could buy a Model T with four months' pay.


Ford's complex safety procedures—especially assigning each worker to a specific location instead of allowing them to roam about—dramatically reduced the rate of injury. The combination of high wages and high efficiency is called "Fordism" and was copied by most major industries. The efficiency gains from the assembly line also coincided with the economic rise of the United States. The assembly line forced workers to work at a certain pace with very repetitive motions which led to more output per worker while other countries were using less productive methods.

In the automobile industry, its success was dominating, and quickly spread worldwide seeing the founding of Ford France and Ford Britain in 1911, Ford Denmark 1923, Ford Germany 1925; in 1921, citroen was the first native European manufacturer to adopt the production method. Soon, companies had to have assembly lines, or risk going broke; by 1930, 250 companies which did not, had disappeared.


Development of automotive technology was rapid, due in part to the hundreds of small manufacturers competing to gain the world's attention. Key developments included electric ignition and the electric self-starter (both by Charles kettering, for the cadillac Motor Company in 1910-1911), independent suspension, and four-wheel brakes.

Since the 1920s, nearly all cars have been mass-produced to meet market needs, so marketing plans often have heavily influenced automobile design. It was Alfred P. Sloan who established the idea of different makes of cars produced by one company, so buyers could "move up" as their fortunes improved.


Reflecting the rapid pace of change, makes shared parts with one another so larger production volume resulted in lower costs for each price range. For example, in the 1930s, Lasalles, sold by Cadillac , used cheaper mechanical parts made by oldsmobile; in the 1950s, chevrolet shared hood, doors, roof, and windows with pontiac; by the 1990s, corporate drivetrains and shared platforms (with interchangeable brakes, suspension, and other parts) were common. Even so, only major makers could afford high costs, and even companies with decades of production, such as Apperson, Cole,Dorris, Haynes, or Premier, could not manage: of some two hundred American car makers in existence in 1920, only 43 survived in 1930, and with the Great Depression, by 1940, only 17 of those were left.


In Europe much the same would happen. Morris set up its production line at Chowley in 1924, and soon outsold Ford, while beginning in 1923 to follow Ford's practise of Vertical integration, buying Hotchkiss (engines), wrigley (gearboxes), and osberton (radiators), for instance, as well as competitors, such as wolseley: in 1925, Morris had 41% of total British car production. Most British small-car assemblers, from abbey to Xtra had gone under. Citroen did the same in France, coming to cars in 1919; between them and other cheap cars in reply such as Renault's 10 CV and Peugeot's's 5 cv, they produced 550,000 cars in 1925, and Mors, Hurtu, and others could not compete. Germany's first mass-manufactured car, the Ope; 4PS Laubfrosch (Tree Frog), came off the line at Russelsheim in 1924, soon making Opel the top car builder in Germany, with 37.5% of the market.

History

Although Nicolas Joseph Cugnot is often credited with building the first self-propelled mechanical vehicle or automobile in about 1769 by adapting an existing horse-drawn vehicle, this claim is disputed by some, who doubt Cugnot's three-wheeler ever ran or was stable. Ferdinand Verbiest, a member of a Jesuit mission in china, built the first steam-powered vehicle around 1672 which was of small scale and designed as a toy for the Chinese Emperor that was unable to carry a driver or a passenger, but quite possibly, was the first working steam-powered vehicle ('auto-mobile'). What is not in doubt is that Richard Trevithick built and demonstrated his Puffing Devil road locomotive in 1801, believed by many to be the first demonstration of a steam-powered road vehicle although it was unable to maintain sufficient steam pressure for long periods, and would have been of little practical use.


In Russia, in the 1780s, Ivan Kulibin developed a human-pedalled, three-wheeled carriage with modern features such as a flywheel, brake, gear box and bearing; however, it was not developed further.

Froncois isaac de Rivan a Swiss inventor, designed the first internal combustion engine, in 1806, which was fueled by a mixture of hydrogen and oxygen and used it to develop the world's first vehicle, albeit rudimentary, to be powered by such an engine. The design was not very successful, as was the case with others such as samuel brown, samuel morey and etienna with hus hippomobile , who each produced vehicles (usually adapted carriages or carts) powered by clumsy internal combustion engines.


In November 1881 French inventor Gustave demonstrated a working three-wheeled automobile that was powered by electricity. This was at the International Exhibition of Electricity in Paris.

Although several other German engineers were working on the problem at about the same time, Karl Benz generally is acknowledged as the inventor of the modern automobile.


An automobile powered by his own four-stroke cycle gasoline engine was built in Mannheim, Germany by Karl Benz in 1885 and granted a patent in January of the following year under the auspices of his major company, Benz & Cie., which was founded in 1883. It was an integral design, without the adaptation of other existing components and including several new technological elements to create a new concept. This is what made it worthy of a patent. He began to sell his production vehicles in 1888.

In 1879 Benz was granted a patent for his first engine, which had been designed in 1878. Many of his other inventions made the use of the internal combustion engine feasible for powering a vehicle.

His first Motorwagen was built in 1885 and he was awarded the patent for its invention as of his application on January 29, 1886. Benz began promotion of the vehicle on July 3, 1886 and approximately 25 Benz vehicles were sold between 1888 and 1893, when his first four-wheeler was introduced along with a model intended for affordability. They also were powered with four-stroke engines of his own design. France already producing Benz engines under license, now added the Benz automobile to his line of products. Because France was more open to the early automobiles, initially more were built and sold in France through Roger than Benz sold in Germany.


In 1896, Benz designed and patented the first internal-combustion engine , called a boxermotor in German. During the last years of the nineteenth century, Benz was the largest automobile company in the world with 572 units produced in 1899 and because of its size, Benz & Cie., became a joint stock company.

Daimler and Maybach founded Daimler motoren (Daimler Motor Company, DMG) in cannstatt in 1890 and under the brand name, Daimler, sold their first automobile in 1892, which was a horse-drawn stagecoach built by another manufacturer, that they retrofitted with an engine of their design. By 1895 about 30 vehicles had been built by Daimler and Maybach, either at the Daimler works or in the Hotel Hermann, where they set up shop after falling out with their backers. Benz and the Maybach and Daimler team seem to have been unaware of each other's early work. They never worked together because by the time of the merger of the two companies, Daimler and Maybach were no longer part of DMG.


Daimler died in 1900 and later that year, Maybach designed an engine named Daimler-Mercedes, that was placed in a specially-ordered model built to specifications set by Emil. This was a production of a small number of vehicles for Jellinek to race and market in his country. Two years later, in 1902, a new model DMG automobile was produced and the model was named Mercedes after the Maybach engine which generated 35 hp. Maybach quit DMG shortly thereafter and opened a business of his own. Rights to the Daimler brand name were sold to other manufacturers.

Karl Benz proposed co-operation between DMG and Benz & Cie. when economic conditions began to deteriorate in Germany following the First world war, but the directors of DMG refused to consider it initially. Negotiations between the two companies resumed several years later when these conditions worsened and, in 1924 they signed an Agreement of Mutual Interest, valid until the year 2000. Both enterprises standardized design, production, purchasing, and sales and they advertised or marketed their automobile models jointly—although keeping their respective brands.


On June 28, 1926, Benz & Cie. and DMG finally merged as the Daimler-Benz company, baptizing all of its automobiles Mercedes Benz as a brand honoring the most important model of the DMG automobiles, the Maybach design later referred to as the 1902 Mercedes-35hp, along with the Benz name. Karl Benz remained a member of the board of directors of Daimler-Benz until his death in 1929 and at times, his two sons participated in the management of the company as well.






Automobile



An automobile or motor car is a wheeled motor vehicle used for tranporting 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. 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). 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.


Etymology

The word automobile comes, via the French automobile, from the Ancient Greek word and the Latin mobilis meaning a vehicle that moves itself, rather than being pulled or pushed by a separate animal or another vehicle. The alternative name car is believed to originate from the Latin word carrus.




Cars is set in a world populated by living vehicles, including automobiles, trucks, trains, and airplanes


The last race of the Piston Cup stock car racing season ends in a three-way dead heat between retiring veteran Strip "The King" Weathers, perennial runner-up and dirty fighter chick hicks, and the self-centered rookie lightning. A tiebreaker race is scheduled for one week later at the Los Angeles International Speedway. McQueen, eager to start practice in california Radiator Springs. A mishap with the local sheriff causes McQueen to inadvertently tear up the town's main road. McQueen is arrested then tried the next day by the town's judge and doctor, who at first wants him to leave immediately; at the insistence of local lawyer sally, Doc instead sentences him to repave the road as community service. as soon as possible in order to become Piston Cup champion and take The King's place as the sponsored car of the lucrative Dinoco team, pushes his driver Mack to travel all night long. Mack tries to avoid falling asleep, but becomes a victim of a gang of reckless street racers, subsequently causing the sleeping McQueen to roll out of the back of the truck unnoticed. Waking up in traffic, McQueen speeds off to find Mack, but becomes lost and ends up in the run-down town of



McQueen initially tries to rush through the job, but makes a sloppy mess of the road and is forced to start again. As the days pass, he becomes friends with many of the townsfolk, and learns that Radiator Springs was once a popular stopover along US route 66. However, the construction of an interstate highway allowed cars to bypass the town, causing many of the businesses and residents to leave. McQueen also discovers that Doc is actually the fabulous, a three-time Piston Cup champion who dropped out of sight after a racing accident ended his career over 50 years ago. Encouraged by his new friends and a countryside cruise with Sally, McQueen successfully completes the road and spends an extra day in town, visiting the local shops to outfit himself with new tires and equipment. That night, Mack and the media converge on the town, having been tipped off by Doc, and McQueen reluctantly starts off for California. Sally is upset with Doc for calling the media, assuming it was best for him and not everyone else.


As the race begins, McQueen's thoughts keep drifting back to Radiator Springs and he is distracted from performing well. However, he is surprised to discover that his new friends have come to serve as his pit crew, with Doc — once again outfitted in his old racing colors — as chief. Cheered by their presence and their incredible pit stop speed, and using tricks he learned during his time among them, McQueen is able to counter Hicks' dirty driving tactics and take the lead. On the final lap, Hicks purposely rams The King aside, causing him to veer off the track and end up in a terrible wreck. Just short of the finish line, McQueen stops, letting Hicks win the race, and backs up to push The King the rest of the way across the finish line, helping him to complete his final race. Hicks is shunned and booed off the awards ceremony stage despite his Cup victory, while McQueen is praised by The King and his wife, Dinoco, and the press and crowd for his sportmanship. He is offered the Dinoco sponsorship but turns it down, saying that he would rather stay with the team that brought him this far. McQueen returns to Radiator Springs and decides to move his team's headquarters there, helping to revitalize the town and its businesses, much to the pleasure of his new friends.
