Cars are a necessity for people's daily travel, and their core components are auto parts. The so-called auto parts refer to the various components that make up the car, including the engine, transmission system, suspension system, braking system, steering system, electrical system, instrument system, etc. Auto parts can be said to be the backbone of the automotive industry, which has an important impact on the quality, performance and safety of automotive products.

First of all, as the core component of the car, the performance of the car engine is related to the power, fuel consumption, emission and life of the car. The engine is divided into two types: a fuel engine and an electric engine. Fuel engines include gasoline engines, diesel engines, and natural gas engines. The combustion chamber of the gasoline engine needs to add mixed gas (a mixture of air and gasoline), which is ignited by the spark plug to generate energy to drive the car. The working principle of a diesel engine is to inject diesel into the combustion chamber through a high-pressure injector, and to drive the car through self-ignition under high pressure and high temperature. The electric motor relies on electric energy to drive the axle and has the characteristics of zero emission.

Secondly, the automotive transmission system is mainly composed of gearboxes, clutches and drive shafts, which are important components that transmit engine power to the wheels. The working principle of the gearbox is to change the size and number of output gears to achieve the purpose of changing the vehicle speed and torque speed. The clutch is responsible for controlling the connection and disconnection of the engine and the gearbox, enabling smooth starting and shifting. The transmission shaft transmits the power output by the gearbox to the wheels, and is also an important part of ensuring the driving of the car.

Furthermore, the suspension system is the first windshield when the car is running, and it plays an important role in the comfort, stability and safety of the car. The suspension system is generally composed of springs, shock absorbers, suspension arms, suspensions and other components. During the driving process of the car, the suspension system can buffer the vibration and bumps of the road surface, stabilize the body and ensure the safety of driving. Different types of car suspension systems will also be different. For example, cars generally use independent suspension, while off-road vehicles use a stronger suspension system.

In addition, the car braking system is also an important part to ensure the safe driving of the car. The braking system generally includes brake pads, brake discs, brake drums, brake fluid and other components, relying on the friction between the brake pads and the brake disc to achieve the purpose of braking. The more advanced the braking system, the stronger the friction between the brake pads and the brake disc, and the better the braking effect. The quality and performance of the braking system directly affect the safety of the car when driving.

Automobile electrical system is one of the commonly used systems in automobiles, mainly composed of batteries, generators, lines, lights and other components. The automotive electrical system can provide electricity for the car, drive the starter to start the engine, supply power to other systems, and provide functions such as lighting and communication to the interior of the car. Its stability and reliability have an important impact on the driving safety and driving comfort of the car.

To sum up, auto parts are various components in the composition of the car, and their quality and performance have an important impact on the performance, fuel consumption, emissions and safety of the car. The automotive industry has higher and higher requirements for auto parts, which promotes the rapid development of the auto parts industry. Therefore, as an important part of the automobile manufacturing industry, auto parts should strengthen technical research and production technology, improve product quality, and further promote the development of the automobile industry.
