Perkins engines are a common type of engine that is widely used in a variety of machinery and vehicles. The cylinder head is one of the most important components of the Perkins engine, and its structure and function have a crucial impact on the performance and life of the engine. This article will introduce in detail the main components of Perkins engine cylinder heads and their functions and functions.
Second, the function and function of each component.
1.Valve seat: The valve seat is the fixed point of the valve, which cooperates with the valve and controls the intake and exhaust of the cylinder. Valve seats are generally made of alloy steel or stainless steel, which has high wear resistance and heat resistance.
2.Valve Guide: A valve guide is a component used to guide the movement of the valve, and it is made of metal or synthetic materials. The inner diameter of the valve guide is matched with the valve stem to ensure stable valve movement.
3.Valve spring: The function of valve spring is to control the opening and closing of the valve, it is made of spring steel, which has good elasticity and fatigue resistance. The elastic force of the valve spring should be moderate, too large or too small will affect the normal opening and closing of the valve.
4.Valve rocker: A valve rocker arm is a part that connects the valve stem and the valve rocker shaft, and it is made of metal or synthetic materials. The length and angle of the valve rocker arm are precisely calculated and adjusted to ensure proper valve movement.
5.Valve rocker shaft: The valve rocker shaft is a component used to support and drive the valve rocker arm, which is made of metal or synthetic materials. The valve rocker shaft should have sufficient stiffness and wear resistance to ensure the stability and reliability of the transmission.
6.Cylinder head bolts: Cylinder head bolts are the parts used to hold the cylinder head, which are made of high-strength steel. The length and diameter of the cylinder head bolts are precisely calculated and selected to ensure the tightness and safety of the cylinder head.
In conclusion, the main components of Perkins engine cylinder heads and their functions and roles are interrelated and mutually influential. In order to ensure the normal operation and performance of the engine, it is necessary to select the right materials and precise processing technology, and at the same time ensure the coordination and coordination between the various components.
