摘要
随着内燃机的性能不断提高,发动机的热负荷与机械负荷随之增加,对气缸盖与缸体间的密封要求也越来越高,因此气缸垫的作用越发重要。缸垫主要负责实现缸体与缸盖之间的微观密封,保证燃烧室、水道、油道的相对独立,避免油气水混合的情况。常见故障主要为漏液和冲缸垫。本文围绕生产工艺引起的内燃机缸垫漏液问题进行了理论分析和试验验证,为发动机开发工作提供技术参考。
With the continuous enhancement of the performance of the modern internal combustion engine, the thermal load and mechanical load of the engine increase accordingly. The requirements for the cylinder head gasket are getting higher and higher.Therefore, the cylinder head gasket becomes more and more important. The cylinder head gasket mainly solves the microscopic seal between the cylinder block and the cylinder head, to ensure the relative independence of the combustion chamber, water channel and oil passage, and to avoid the mixing of oil, gas and water. Common failures are leakage and cylinder head destroy;In this paper, theoretical analysis and experimental verification are carried out to solve the problem of cylinder head gasket leakage caused by production process,which can provide reference for solving this kind of problem.
