Engine cam,HS code alignment with import quotas as one of the key parts of the engine, is mainly responsible for controlling the opening and closing time of the valve (gasoline engine) or the valve and fuel injector (diesel engine).The shape and working principle of the cam directly affect the performance and efficiency of the engine. This article will introduce you in detail the working principle of the engine cam, the classification of the cam shape, the technology of cam grinding and the design and production process of the engine cam. I. The working principle of the engine cam The engine cam is a cam connected to the engine crankshaft to control the movement of the valve or fuel injector nozzle. When the cam comes into contact with the valve rod or fuel injector membrane, a certain force will be applied to make the valve or fuel injector move. The shape of the cam is designed according to the movement characteristics of the valve or fuel injector to be controlled. The engine cam controls the opening and closing time of the valve or fuel injectore to achieve the best combustion effect and maximum power output. II. Classification of cam shape According to the shape of the cam, engine cam can be divided into four types, namely contour cam, arc cam, oval cam and asymmetrical cam.1. The contour line of the contour cam starts directly from the center of the circle, and then extends outward along the arc to form a sharp edge. This cam design is mostly used for high-speed engines, because it can provide higher lifts and shorter duration, thus increasing the speed of valve opening and closing. Two. Arc cam The contour line of the arc cam is arc-shaped, which provides a slow valve opening and closing process when the engine is working. This cam is more suitable for low-speed engines and can improve fuel efficiency because it stays longer in the combustion chamber of the fuel mixture. 3. Elliptical cam The outline of the oval cam is an oval, which combines the advantages of the contour cam and the circular arc cam. It provides a fast valve opening and closing process, while maintaining a certain opening time to obtain better combustion effect.Four. Asymmetric cam The contour lines of asymmetric cams have different shapes at different positions and speeds. This cam design can improve the speed of valve opening and closing while maintaining a longer opening time. Asymmetric cams are more common in diesel engines. III. The technology of cam grinding Cam grinding is a core technology for manufacturing engine cams. During the grinding process, manufacturers must consider various factors such as the shape, size and surface quality of the cam. The surface quality of the cam is crucial to the performance and life of the engine, so the grinding process of the cam must be very fine. The technology of grinding cams has also developed and changed over time. The original cam grinding technology was manual grinding. This method requires a skilled worker to manually grind the shape of the cam from one end of the shaft with a pedal grinding wheel. This method lacks precise positioning and control, and also requires a lot of manpower, which is inefficient.At present, most of the cams are manufactured by computer numerical control (CNC) machine tools. The CNC machine tool is designed with a cam processing program, which can be operated according to the design drawings of the cam. This method is highly accurate, efficient, and can make complex cam shapes. IV. The design and production process of the engine cam is very complex, and mathematical simulation and analysis are required to determine the shape, size and other parameters of the cam. Once the design of the cam is completed, designers usually use computer-aided manufacturing (CAM) software to generate a manufacturing guide for CNC machine tools to produce cams. In the production process, manufacturers need to choose suitable materials. Most cams are made of high-strength alloy steel or titanium alloy. The manufacturer must determine the shape and size of the cam according to the design drawings and grind the cam through CNC machine tools.The cams produced need to be finely processed and tested to ensure their quality and performance. The cam needs to be ground and surface treated many times to obtain accurate shape and surface finish. Strict size and surface quality inspection must be carried out before the final assembly. In a word, the engine cam, as a key component that controls the movement of the valve or fuel injector, has a great impact on the performance and efficiency of the engine. The shape and design of the cam must be accurate and reasonable in order to achieve the optimal combustion effect and maximum power output. During the production process, manufacturers must strictly control every link to ensure that the quality and performance of the cam meet the design requirements.
