The car (car) is a two-wheel motor vehicle, usually road, which is used for the transport of goods and passengers. Sometimes under the car does not mean buses and trucks, i.e., This includes only passenger cars. Most car definitions say that it primarily moves along the roads, can get up to eight people, have four tires, and main transport people, rather than a load. Cars entered global use during the 20th century, and developed economies are dependent on them. The year 1886 is considered to be the birthday of a modern car. That year, the German inventor Karl Benz made Benz Patent-Motorvagen. The car did not become widely available until the early 20th century. One of the first cars available to the masses was the Model T of 1908, an American car that produced the Ford Motor Company. The cars were quickly accepted in the United States, where they were replaced by animals of trained carriages and carts, while in Western Europe and other parts of the world, it took much longer to stabilize.
Cars have control for driving, parking, comfort and safety of passengers, and control of various lights. During the decade, additional functions and controls have been added by vehicles, making them gradually more and more complex. Examples include rear-facing rear-view cameras, air conditioning, navigation systems and car entertainment appliances. Most of the cars in use in 2010 are powered by internal combustion engines that consume fossil fuels. This causes air pollution, contributes to climate change and global warming. Vehicles using alternative functions, such as ethanol vehicles with flexible fuel and natural gas vehicles, are gaining popularity in some countries. Electric cars, which were invented earlier in the history of cars, and began to appear on the market since 2008.
The word “car” of Greek origin is the Greek “αυτο” (“auto”), autonomous and Latin origin, the Latin “mobilize” in the meaning of mobile. The car is etymologically defined as a self-moving vehicle, and it is not dependent on rails or trolleys, whose movements do not require animals or human force, and which moves through its drive.
Engines used in automobiles are piston engines with internal combustion, most commonly used as gasoline or diesel fuels. Liquid petroleum gas (LPG) or, as is often called gas, is used as an alternative fuel type, while other types of alternative fuels are not yet widespread.
Electric motors have much greater efficiency than internal combustion engines, but since they use heavy batteries as a source of energy, they do not use much to drive the car.
Cars represent an important source of pollution. It is caused by the presence of carbon dioxide, carbon monoxide, nitrogen oxides, unburned hydrogen and oxide water in exhaust gases. For vehicles with octagonal motors, the reduction in the number of harmful gases is achieved by their “spinning” in the catalytic reactor (“catalyst”), which is located in the exhaust pipe. The existence of a catalyst requires the use of unleaded motor gasoline.
For short distances, especially for city driving, more and more electric cars are used, whose capacity is sufficient to provide an understandable radius of movement, without being too crowded.
