摘　　要：通用小型汽油机的密封既有静密封问题,又有动密封问题,而以静密封为主。影响静密封性能的主要因素有密封材料的性质、垫片性能参数、安装操作等。影响通用小型汽油机密封性的因素有很多,如密封面的加工精度、粗糙度等,在解决密封问题时都应该根据具体情况予以综合考虑。The seal of general utility small gasoline engine includes static seal and dynamic seal. Static seal is the main method. The major factors that influence the static seal includes seal material character, gasket performance and fixing, operation, etc. In fact, there are so many factors that influence the seal of general utility small gasoline such as the machining precision and roughness of seal surface. We should consider synthetically according to the specific condition when we deal with the seal problem.
