Internal combustion engine occupies a very important social position in power machinery. The internal combustion engine has high thermal efficiency, high power and zero line coordination, so the mechanical kinetic energy must have good application characteristics and advantages. It can be widely used in mechanical devices. As an important part of power plant, vermicular graphite cast iron internal combustion engine can cast cylinder block and cylinder head in an all-round way. In operation, the combustion temperature of the combustion chamber of the internal combustion engine can reach about 2000 ℃ in general. Cylinder block and cylinder head should have obvious high temperature bearing capacity in use. Therefore, the selection of vermicular graphite cast iron technology can ensure that it can withstand the high temperature cycle, but also can withstand the impact of high pressure gas, to ensure the industrial production efficiency and the construction safety of related workers. For the construction personnel, in the application of internal combustion engine, vermicular graphite cast iron technology can provide effective convenience for its own workflow. The high pressure and high load of internal combustion engine are also enhanced. The combustion chamber has uniform intake and thermal conductivity, which gradually reduces the internal temperature and effectively reduces the impact of steel caused by internal thermal stress.
With the continuous development of China’s social strength, how to comprehensively reduce the thermal power of internal combustion engine has become an important research topic in China. The production efficiency of internal combustion engine is gradually developing towards the direction of high power, low energy consumption, low pollution and low noise, which can ensure the significant reduction of pollutants in the emission process.
In the process of application in our country, with the comprehensive enhancement of the industrial field, the industrial level of our country will be comprehensively improved. It is a unique skill of our country to absorb foreign excellent technology. For example, vermicular graphite cast iron technology. Therefore, as far as the content of vermicular graphite cast iron technology is concerned, it covers the exhaust pipe, cylinder block, cylinder head and other parts. In the field of enterprise application in China, such as China National Heavy Duty Truck, Yuchai and other enterprises, the application performance of vermicular graphite cast iron has been effectively recognized. And start mass production, strengthen the vermicular graphite cast iron as the leading basic internal combustion engine castings. In the process of use, it can produce great significance to the production efficiency of internal combustion engine. Internal combustion engine in the production process, its own external factors, can produce obvious mechanical stress. The cylinder block and cylinder head of internal combustion engine bear more thermal stress loss. It can be seen that the cylinder block and cylinder head of internal combustion engine belong to complex thin-wall structure. Therefore, in the process of use, it may appear obvious pressure impact for high temperature, which puts forward new requirements for the strength and heat resistance of internal combustion engine. Vermicular graphite cast iron technology can meet the above requirements, at the same time, it has more application effects. In view of the cylinder block, cylinder head and other structures of internal combustion engine, the comprehensive application is carried out.
