What are the main components of a sedan?

A car is mainly composed of four major assemblies: the body, engine, chassis, and electrical equipment. It is the power unit of the car. Its function is to burn fuel to generate power, which then drives the wheels through the chassis's transmission system, enabling the car to move. There are two types of engines: gasoline engines and diesel engines. A gasoline engine consists of the crankshaft-connecting rod mechanism, valve train, fuel supply system, cooling system, lubrication system, ignition system, and starting system. Diesel engines use compression ignition, so they do not have an ignition system. The chassis serves to support and mount the car's engine and its components and assemblies, forming the overall shape of the car. It receives power from the engine, enabling the car to move and ensuring normal operation. The chassis consists of four parts: the transmission system, driving system, steering system, and braking system. The body is mounted on the chassis frame and provides space for the driver and passengers or for carrying goods. The electrical equipment consists of the power source and electrical devices. This includes the power battery and generator. Electrical devices include the engine starting system, gasoline engine ignition system, and other electrical equipment.
Having driven for over a decade, I've found that sedans primarily consist of several core components. The engine acts as the heart of the car, responsible for generating power; the transmission functions like a power-translating interpreter, smoothly delivering that power to the wheels. The chassis system includes braking, suspension, and steering components, ensuring stable and safe driving. The body frame protects passenger safety, covered by various exterior panels. The electrical system is crucial, encompassing the battery power supply, complex wiring networks, various lights, and control panels. The interior also features comfort-enhancing components like air conditioning, seats, and instrument panels. Modern vehicles now incorporate intelligent accessories such as radars and cameras, making driving even more reassuring.
