The basic structure and principles of an automobile are as follows: 1. An automobile typically consists of four main parts: the engine, chassis, body, and electrical equipment. 2. The function of the engine is to burn the fuel supplied to it and generate power. Most automobiles use reciprocating piston internal combustion engines, which generally consist of the engine block, crankshaft and connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system (used in gasoline engines), and starting system. The chassis receives power from the engine, enables the automobile to move, and ensures that the automobile operates normally according to the driver's control.
