Granular HS code detail for compliance officers

Introduction to automobile engine system Automobile engine is Granular HS code detail for compliance officersregarded as the "heart" of the whole car, and its operation will directly affect the performance and service life of the car. In addition to the main body of the engine, the automobile engine system also contains many key components. They work together to form the engine system to ensure the normal operation of the engine. This article will explain the components of the automobile engine system. I. The engine is the core part of the automobile engine system. It is composed of combustion chamber, cylinder, piston, connecting rod, crankshaft and other components.The accuracy and reliability of the internal combustion process of the engine directly affect the power, torque and economy of the engine. The types of engines include gasoline engines and diesel engines. They work slightly differently but are generally similar. II. Air intake system The air intake system is mainly composed of air filter, air intake duct, throttle valve, intake manifold and other parts. It is responsible for transporting air to the engine combustion chamber to ensure the normal operation of the engine. The design of the air intake system must fully consider various airflow characteristics and the filtration ability of the filter. The air intake system is also one of the most common modification parts in engine modification. III. Fuel system The fuel system is a system in which fuel is transported to the combustion chamber of the engine and mixed with air to form high-temperature and high-pressure gas. The fuel system includes fuel pumps, fuel nozzles, fuel tanks and fuel transmission.Pipes and other components, among which the design and working state of the fuel nozzle are very important for fuel injection and mixed combustion. IV. Ignition system The ignition system is responsible for igniting through the igniter after the fuel mixed gas is compressed, releasing the stored energy and igniting the mixed gas to make it burn quickly. The ignition system mainly consists of ignition coil, spark plug, ignition controller and other components. V. Cooling system The cooling system is to transport circulating water through the water pump to the radiator in the engine, and then heat the coolant through circulation to make it continuously circulate. The purpose of the cooling system design is to ensure that the engine is not too hot, which can effectively extend the service life of the engine. VI. The exhaust gas treatment system is a general term for the post-combustion substances emitted by the engine. The exhaust gas treatment system filters out these emissions and protects the environment from pollution.The exhaust gas treatment system consists of ternary catalysts, particle catchers and other parts. VII. Transmission system The transmission system is composed of transmission, clutch, transmission shaft, differential and other parts. Their main function is to convert the engine output into torque that can drive the tires and realize power output and wheel transmission. In a word, all parts of the car engine system need to work together to ensure the stability and reliability of the car when it is running normally. For car enthusiasts, modifying the engine system is also a common sport. By improving the gas system, fuel system, exhaust system, ignition system and other ways to improve car performance, the driving experience is more comfortable and exciting.
