car

The adjective car is used to refer to that which has mobility by itself. The term, par excellence, is used as a noun to name the car.

Automobiles, therefore, are Motor vehicles that can move without the need for tracks or rails. Also called cars or cars, are used for the transfer of people.

Most cars have engines from internal combustion. In this case, a fuel (gasoline or naphtha, diesel or diesel, CNG, etc.) that, when in contact with a oxidizer (oxygen), reacts and produces combustion. This process generates a release of thermal energy that is then transformed into mechanical energy to promote movement.

In recent years, however, cars with electric motor. These means of transport have batteries that store electricity: the electric power, thanks to the action of the motor, it is converted into mechanical energy.

It is important to note that there are multiple types of cars. At a general level, it can be said that automobiles have a chassis that sustains the bodywork; four wheels with tires Y tires; a motor with gearbox; a steering wheel for driving; Y pedals to accelerate and brake. Of course, many other elements, systems and mechanisms are part of these machines.

Despite the great advantages that cars offer when going from one place to another, these vehicles usually produce polluting emissions that affect the environment. That is why there are campaigns that discourage car travel and promote, instead, transfers in bike or in Public transportation (which allow many individuals to be carried in the same unit).
