What is the power source of a car and what are the components?

The power source of a car is the power provided to the car, that is, the engine or motor, is the engine or motor power transmission to the gearbox, and then to the wheels, the composition of the engine, cylinder head, cylinder block, oil sump, intake and exhaust systems, fuel system, etc., a lot of parts of the composition.

The engine is the core part of the engine, so it is customary to use engine to refer to the engine. The main part of the engine is the cylinder, which is the source of power for the entire automobile.

Extended information:

The cylinder is injected with gasoline and air through the intake and delivery holes, which are well-mixed within the cylinder, and when the spark plug ignites the mixture, the mixture violently explodes and burns, pushing the piston downward and generating power. At the same time, the huge pressure of the explosive gas also pushed open the check valve outlet hole, exhaust gas.

And then, the cylinder residual exhaust gas gradually become cold, the air pressure becomes low, the atmospheric pressure outside the cylinder and push the piston upward movement, in preparation for the next explosion. This is the simple principle. Now also used as a term of IT, refers to the library of packaged functions to facilitate others to call, such as search engines, graphics engines, physics engines.
