How to simplify HS code selection

Car engine compartment (car engine compartment) Understanding the car engine compartment from the inside is How to simplify HS code selectionone of the important components of the car and the core of the car. Its main function is to accommodate, protect, cool, replenish engines and other mechanical parts, and is also responsible for separating drivers and passengers to ensure driving safety. It is the concentration of automobile engines, because all relevant components are concentrated here, such as engines, electrical systems, braking systems, transmissions and drive shafts, etc. Next, we will learn about the car engine from the inside. I. The position of the engine. The engine compartment of the car is usually located at the front of the vehicle, that is, under the hood. Sometimes, the engine compartment of a car may be in the rear or middle of the vehicle, such as a mid-engine sports car and racing car. II. The main parts of the engine compartment of the car 1.The engine is the most important part of the car's engine compartment. It is the source of car power, which can convert fuel into energy and transfer energy to the wheels to push the vehicle forward. The engine usually occupies most of the space in the front engine compartment of the vehicle. Two. The internal combustion engine of the cooling system generates a large amount of heat when it is working, so a complete cooling system is needed to coordinate this heat. The cooling system usually includes components such as radiators, pumps, coolants, fans, heat exchangers and sensors. 3. Electrical system Electrical system is one of the important parts of the whole engine compartment. It mainly includes batteries, generators, ignition systems, wires and fuses and other parts. The electrical system plays a crucial role in the start-up, charging and ignition of cars. Four. Braking system Braking system is one of the most important safety parts in the engine compartment of a car.It consists of a brake disc, a brake calliper, a brake pad and a hydraulic system. By using the braking system, the driver can slow down or stop the car completely. 5. Transmission and transmission shaft The transmission in the engine compartment of the car is responsible for transmitting the power provided by the engine to the wheels through the transmission shaft. Transmissions are usually divided into two types: manual and automatic. III. Maintenance of the engine compartment of the car After the car has been used for a period of time, the engine compartment needs to be maintained. Here are a few things to pay attention to: 1. Change the engine oil to keep the engine lubricated and cooled 2. The cooling system uses coolant to prevent the engine from overheating 3. Pay attention to replace the air filter and fuel filter to ensure clean air and fuel supply to the engine 4. Observe the battery power and cleaning electrode 5. Replace the worn brake pads to ensure the systemThe normal operation of the dynamic system IV. Summary: The engine compartment of the car is one of the important components of the car and the core of the car. It includes the engine, cooling system, electrical system, braking system, transmission and transmission shaft and other parts. Through the perfect coordination of these components, the safety and performance of the car during operation can be ensured. We can extend the service life of the car and ensure the performance and safety of the car through regular maintenance and maintenance of the car engine compartment.
