The Free zone HS code compliancecylinder head of the engine - the valve chamber and head parts of the engine The engine is the heart of modern cars, and the cylinder head is a very important part of the engine. It not only has the function of protecting the engine, but also has important functions such as carrying pressure and regulating the volume of the combustion chamber. The structure and function of the cylinder head will be introduced in detail below. I. The structure of the engine cylinder head 1. The surface of the cylinder head refers to the appearance of the cylinder head, which is generally smooth.In order to improve the wear resistance and corrosion resistance of the surface of the cylinder head, its surface treatment, such as powder spraying or painting, is usually required. Two. Cylinder head valve chamber The cylinder head valve chamber refers to the cavity inside the cylinder head, which is the place where the valve and fuel injector are installed. Its shape and size play a crucial role in the performance and fuel efficiency of the engine. Usually, the cylinder head valve chamber is designed according to the working principle and structure of the engine. 3. Cylinder head parts The cylinder head parts usually include camshafts, valve springs, valve wrenches, fuel nozzles, etc. These parts work together with the design of the cylinder head valve chamber, so that the compression chamber of the engine can operate normally and achieve higher efficiency and performance. II. The function of the engine cylinder head 1. Protecting the inside of the engine is very complicated, and there are many important parts that need to be protected.As a component of the top of the engine, the cylinder head can protect the inside of the engine from smaller debris, sand, dust and moisture from the outside. Two. The bearing pressure engine will generate a lot of pressure when working. Without the support of the cylinder head, the engine will be difficult to withstand these pressures. The cylinder head is like a cover, which can withstand the internal pressure of the engine and make it run smoothly. 3. Adjusting the combustion chamber volume of the combustion chamber volume of the engine determines the performance of the engine. The size and shape of the cylinder head design can create more space inside the combustion chamber, make the combustion process more complete and improve the output power of the engine. Four. The high temperature inside the heat dissipation engine will affect the performance and life of the engine. The cylinder head plays an important role in heat dissipation, which can ensure that the engine will not overheat during operation.At the same time, some designs and holes on the cylinder head can also allow warm airflow, so that the engine can cool down faster and improve the stability of the engine. 5. The performance of the engine. The cylinder head plays a crucial role in the performance of the engine. Because the valve chamber and head parts of the cylinder head can affect the combustion chamber capacity and fuel efficiency of the engine, the quality of the cylinder head has a direct impact on the performance of the engine. In summary, the engine cylinder head is a key part that plays a very important role in the engine. It not only protects the interior of the engine, carries pressure and regulates the volume of the combustion chamber, but also dissipates heat and affects the performance of the engine. Therefore, the design and manufacturing process of the cylinder head are crucial to the overall performance and life of the engine.
