Pharma excipients HS code classification

* [Engine parts nameIntroduction to weighing and Pharma excipients HS code classificationfunction] The engine is one of the most important components of the vehicle, because it provides the necessary power and rotation power to keep the vehicle running. However, the engine is not just a single component that can generate power, it is composed of a variety of parts. The following are some common engine parts names and a brief introduction to their functions. I. Piston piston is one of the main components of the engine. It is a component that can move according to the operation of the engine. The main function of the piston is to convert the thermal energy generated in the combustion chamber into mechanical energy so that the vehicle can be started. It is usually made of cast iron or aluminum alloy and needs to be replaced regularly to ensure the normal operation of the engine. II. Connecting rod is another important part of the engine. It is located under the piston and is responsible for transforming the movement of the piston into the movement of the crankshaft.It is usually made of high-strength steel or aluminum alloy to withstand the torsion force from the piston to the crankshaft. III. The crankshaft is also one of the indispensable parts of the engine. It is a hinge in the crankcase, which can convert the up and down movement of the piston into rotational motion. The crankshaft is generally made of high-strength steel and has strong wear resistance. Its operation generally relies on the swing of the crankshaft waist to generate power. IV. The cylinder head is a part installed on the cylinder. Its function is to seal the cylinder so that the pressure in the cylinder will not leak to the outside. It is usually made of aluminum alloy, cast iron or stainless steel and other materials, with high heat resistance, corrosion resistance and wear resistance to ensure the normal operation of the car. V. The cylinder liner is a part inside the engine that can accommodate the piston. The inner diameter of the cylinder liner is usually the same as the outer diameter of the piston to ensure that the piston can move freely in the cylinder head.It is usually made of copper, alloy or iron to meet the needs of high-temperature, high-pressure and high-load working environments of automobiles. VI. The main function of the intake pipe is to introduce external air into the engine and then mix it with fuel to produce combustion. It is usually made of materials such as plastic, metal or carbon fiber to ensure that it can withstand the high-temperature and high-pressure working environment of the engine. VII. The exhaust pipe, like the intake pipe, is also a very important part. Its main function is to export the exhaust gas generated by combustion in the engine to the engine to reduce the pressure inside the engine, thus improving the efficiency of the engine. It is usually made of stainless steel or titanium to ensure durability and corrosion resistance. In car repair and maintenance, these engine parts need to be checked and replaced frequently. For car maintenanceFor routine operation, these components should be closely followed to ensure the smooth operation and efficient operation of the engine. At the same time, accurately diagnosing faults and dealing with them in time is the key to ensuring the long-term stable operation of the engine. In short, engine parts are a crucial part of the car, and the failure of any parts may cause damage to the engine or other serious accidents.
