发动机活塞与气缸的配缸间隙是极为重要的技术参数。不同车型的发动机,特别是现代强化发动机,由于其各自的结构、材质及其他各种技术参数不同,活塞与气缸的配缸间隙也不尽相同,贵刊1998年第11期刊登的焦兴龙先生《浅谈减小配缸间隙》一文中说:“……汽车都具有一定的储备功率,发动机实际上往往不是在最大功率和最高温度状况下工作。因此修理手册和说明书中所规定的配缸间隙往往不是发动机大修时应有的配缸间隙。在大修时,有必要根据现代发动机气缸和活塞的材质、加工精度和产品结构等特点,对原厂规定的配缸间隙作适当的修正(减小)。”文中并阐述了理由,给出了减小配缸间隙的计算公式。笔者认为,不论何种发动机,其合理的配缸间隙都是由制造厂家根据发动机的结构特点、
Engine piston and cylinder with cylinder clearance is extremely important technical parameters. Different models of engines, especially the modern enhanced engine, due to their different structures, materials and other technical parameters of different piston and cylinder with cylinder clearance is not the same, published in 1998, No. 11, published by Mr. Jiao Xinglong “ Talking about reducing the cylinder clearance with a ”article said:" ... ... cars have a certain reserve power, the engine is often not in the maximum power and maximum temperature conditions work.Therefore, repair manuals and instructions specified cylinder clearance Often not when the engine overhaul should be equipped with cylinder clearance.In the overhaul, it is necessary according to the modern engine cylinder and piston material, machining accuracy and product structure and other characteristics of the original provisions of the cylinder with the appropriate amendments to the gap (reduced In the article, the reasons are given and the formula to reduce the clearance of cylinder is given. In my opinion, no matter what kind of engine, its reasonable distribution cylinder clearance are by the manufacturer according to the structural characteristics of the engine,
