Understanding Automobile Structure?

A car is generally composed of four basic parts: the engine, chassis, body, and electrical equipment. Here is a detailed introduction: 1. Engine: The engine consists of 2 major mechanisms and 5 major systems: the crank-connecting rod mechanism; the valve train; the fuel supply system; the cooling system; the lubrication system; the ignition system; and the starting system. 2. Chassis: The chassis serves to support and install the car engine and its various components and assemblies, forming the overall shape of the car, receiving the power from the engine to make the car move and ensuring normal driving. The chassis is composed of four parts: the transmission system, the running system, the steering system, and the braking system. 3. Body: The body is mounted on the frame of the chassis and is used for the driver and passengers to sit or to carry goods. The body of a car or bus is generally an integrated structure, while the body of a truck is generally composed of two parts: the cab and the cargo box. 4. Electrical Equipment: The electrical equipment consists of two major parts: the power supply and the electrical devices. The power supply includes the battery and the generator; the electrical devices include the starting system of the engine, the ignition system of the gasoline engine, and other electrical devices.
My understanding of car structures stems from years of passion for driving and modifications. A car is like a precision machine, divided into several main parts: the engine bay, which is the power core, including the engine and cooling system—the engine burns fuel to generate horsepower; the drivetrain is responsible for transmitting power, consisting of the transmission and differential; the chassis serves as the skeleton supporting the entire vehicle, incorporating the suspension and braking systems to ensure smoother rides; the body section is made up of the frame and shell, protecting occupants with doors and windows; finally, the electrical system manages all electronic devices, such as lights and air conditioning. I’ve found that maintaining the structure is crucial—regularly checking engine fluids and suspension wear can prevent major repairs. Knowing these details during road trips helps me handle sudden breakdowns more calmly, like checking coolant levels when the engine overheats.
