1简介各种机动车内燃机长期运行过程中均会出现油路不畅、启动困难、气缸工作噪音大、动力减弱、耗油量大、尾气黑烟严重等现象。究其原因系油路、燃烧系统附着的胶状物质、油垢、积炭所致。传统办法是停车拆机维修，有针对性的更换或拆洗各零部件，既误工误时，又增加维修费用 1 INTRODUCTION In the long-term operation of various types of automotive internal combustion engines, there are phenomena such as poor oil passage, difficulty in starting, large cylinder noise, weak power, large fuel consumption, and serious tail gas smoke. The reason for this is due to the gluey substances, grease, and carbon deposits attached to the oil circuit and combustion system. The traditional method is to stop and disassemble the machine for maintenance, and to replace or disassemble parts and components in a targeted manner. When misuse is missed, the maintenance cost increases.
