The four major components of a car are the body, engine, chassis, and electrical system. The body is the part of the vehicle used for carrying passengers or cargo, including the body shell (frame), exterior body panels, interior trim, and electrical accessories. The body of a sedan or bus is generally a unitary structure, while the body of a truck usually consists of two parts: the cab and the cargo compartment. Based on whether it bears the chassis structure, car bodies can be classified into three types: unibody, semi-unibody, and body-on-frame. The heart of the car—the engine. The engine burns fuel to generate power, which is then transmitted through the chassis drivetrain to propel the vehicle. The valve train consists of the cooling system, lubrication system, starting system, ignition system, and fuel supply system. Components such as the transmission, rear axle, and wheels belong to the chassis. The chassis supports the entire vehicle and receives power from the engine to drive the car. All other parts of the car are assembled on the foundation of the chassis. According to their different functions, the chassis can be divided into four major systems: the suspension system, steering system, drivetrain system, and braking system. The car's electrical system is mainly divided into two categories: power generation and electrical equipment. The power generation category consists of the alternator and battery, while the electrical equipment category includes lighting devices, display devices, ignition systems, regulators, audio systems, etc.
