What are the basic structure and principles of an automobile?

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.

I've been driving for almost twenty years, and the basic structure of a car is like a big metal box, composed of the engine, chassis, body, and electrical system. Simply put, the principle is energy conversion: the engine burns gasoline to create an explosion, which pushes the pistons to rotate. The energy is then transmitted to the transmission and finally to the wheels, making the car move. The chassis ensures stable suspension, and the braking system stops the car when you press the pedal, ensuring safe driving. The body protects us, while the electrical system manages the lights and air conditioning, making driving more comfortable. Regular maintenance is essential, such as changing the engine oil periodically and checking the brakes, otherwise, minor issues may arise, making the drive less smooth.

I usually tinker with various vehicles, and my understanding of car construction is quite simple: the core is the powertrain. The engine generates power by burning fuel, similar to a small factory, with four strokes: intake, compression, expansion, and exhaust. The transmission system transfers the power to the wheels. The chassis includes the suspension and braking systems, making the ride smoother and stopping more stable. The body provides space, while the electrical system handles lighting and controls. In principle, it's about converting chemical energy into mechanical energy, and modern cars also have computer chips managing everything. Electric vehicles are quite different, using electrical energy to directly drive the motor, with no pollution, making them more suitable for urban commuting—quiet and cost-effective to drive.

When I first started learning to drive, my instructor taught me that the basic structure of a car is divided into several parts: the engine, transmission, chassis, and body. The principle of the engine is to burn fuel into power, the gearbox helps us shift gears, the chassis provides suspension and brakes to ensure safety, the body encloses the passengers, and the electrical system powers the lights. Simply put, the car moves by turning the wheels. Daily driving with simple checks on the tires and battery can reduce breakdowns, and understanding these basics makes driving more reassuring.
