There is a lot of knowledge about cars. Definition of a car: The latest national standards on the terminology and definitions of motor vehicles and trailers define a car as follows: a non-track vehicle powered by an engine, with four or more wheels, primarily used for transporting people and/or goods, towing vehicles carrying people and/or goods, or for special purposes. Car structure: The engine is the power unit of a car, consisting of 2 major mechanisms and 5 major systems, such as the crank connecting rod mechanism, valve train, cooling system, fuel supply system, lubrication system, ignition system, and starting system. However, diesel engines have one less ignition system compared to gasoline engines.
