Introduction
An automobile or motor car is a wheeled motor vehicle for transporting passengers; which also carries its own engine or motor. Most definitions of the term specify 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.
Automobile comes via the French language, from the Greek auto [self] and mobiles [moving]; meaning a vehicle that moves itself, rather than being pulled or pushed separate animal or another vehicle.
Although Nicolas-Joseph Cugnot is often credited with building the first self -propelled mechanical vehicle or automobile in about 1769.Richard Trevithick built and demonstrated his Puffing Devil road locomotive in 18 In 1892, German engineer Rudolf Diesel was granted a patent for a "New Rational Combustion Engine”. In 1897 he built the first Diesel Engine. In 1895, Selden was granted a United States patent (U.S. Patent 549,160) for a two-stroke automobile engine. Steam, electric, and gasoline-powered autos competed for decades, with gasoline –internal combustion engines achieving dominance in the 1910s.01, the first truly successful steam-powered road vehicle.
FUEL AND PROPULISION 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.
DIESEL (DIESEL ENGINE) Diesel-engine cars have been popular in Europe with the first models being introduced
