What does a car consist of? What is a car made of

There used to be two kinds of formulations in textbooks about the composition of a car. The first type: the car consists of four parts, namely the engine, the chassis, the body, and the electrical (electrical).

The second type: the car is composed of three parts, namely the engine, chassis, body and accessories. The first formulation is more common.

Whether it is the four parts or the three parts, once you are familiar with the structure of the car, you will understand that the engine, chassis, and body are the three main parts of the car, and many electrical equipment or electronic control systems are actually divided into the engine, chassis, and body, and there are also electrical equipment that do not belong to these three parts, such as lighting devices, signal devices, power supply equipment, etc. Take the battery (storage battery) as an example, it not only supplies power to the engine, but also supplies power to other electrical equipment of the car, so it can be said that it belongs to the whole car. Let me give a brief explanation of these four parts.

1. The engine, which powers the car, is known as the heart of the car. The most widely used automobile engines are gasoline engines and diesel engines, in addition to gas engines. Pure electric vehicles are driven by electric motors, and hybrid vehicles have both an electric motor and an internal combustion engine.

The two mechanisms and five systems that make up the gasoline engine are: crankshaft connecting rod mechanism, gas distribution mechanism, fuel system, lubrication system, cooling system, ignition system, and starting system. The diesel engine is a compression-ignition engine with no ignition system, that is, two bodies and four series.

2. Chassis: The role of the chassis is to transmit the power of the engine to the wheels, drive the car, and ensure that the car runs normally according to the driver's intentions. The four systems that make up the chassis are: drive train, driving system, brake system, and steering system.

3. Body: The body is mounted on the frame of the chassis to accommodate the occupants or load goods.

4. Electrical appliances (electrical): electrical appliances include power supplies, electrical equipment, signals and lighting devices, and the software and hardware of electronic control systems widely used in modern automobiles, which are sometimes summarized into the electrical system.

According to its general structure and the functions of each part, the car is often composed of four parts: engine, chassis, body, auxiliary electrical appliances and electronic equipment.

A car is usually composed of four parts: engine, chassis, body and electrical equipment.

1. Engine: crank connecting rod mechanism, gas distribution mechanism, fuel supply system, ignition system, lubrication system, cooling system and starting system.

2. Chassis: drive train, driving system, steering system and brake system. The drive train is to transmit engine power to the drive wheels, which is composed of clutch, transmission, universal transmission, final reducer and other assemblies.

The driving system consists of a frame, a steering axle, a drive axle, a suspension, wheels, etc. The steering system consists of a steering gear and a steering mechanism. The braking system is generally composed of two independent devices, namely the service brake system and the parking brake system.

3. Body: used to place the driver, passengers and goods.

4. Electrical appliances: composed of power supply, ignition system, starting system, automotive lighting system, signal system and instrumentation.

Engine, chassis, body, electrical equipment.

Usually a car consists of four parts: engine, chassis, body, and electrical equipment.

The role of the engine is to make the fuel supplied to it burn and generate power. Most automobiles use reciprocating piston type internal combustion engine, which is generally composed of body, crank connecting rod mechanism, valve mechanism, supply system, cooling system, lubrication system, ignition key fire system, starting system and other parts.

The chassis receives the power of the engine, makes the car move, and ensures that the car runs normally according to the driver's control.

The body is the place where the driver works, as well as the place where passengers and goods are loaded. The body should provide convenient operating conditions for the driver to lift the luggage chain, as well as provide a comfortable and safe environment for passengers or ensure that the goods are intact.

The electrical equipment consists of a power pack, an engine starting system and an ignition system, automotive lighting and signaling devices, etc.
