积炭是内燃机的燃料和润滑油在高温及氧化作用下的生成物。当燃料及窜入燃烧室的润滑油不能完全燃烧时,未燃部分的胶质粘附在零件表面上,被高温烤灼及氧化成为沥青质、油焦质和炭青质等复杂混合物,于是形成了积炭。积炭是一种有害有毒的物质。积炭的危害 1.导致早燃积炭粘附在组成燃烧室的各零件表面,缩小了燃烧室容积,改变了压缩比及工作性能。同时积炭成为许多炽热点,容易诱发早
Coke is the combustion engine fuel and lubricants in the high temperature and oxidation products. When the fuel and the fledging into the combustion chamber of the lubricating oil can not be completely burned, the unburned part of the gum adhesion to the surface of parts, high temperature baking and oxidation into asphaltene, oil coke and carbon green complex complex, then Formed a coke. Coke is a harmful and toxic material. The hazards of coke 1. Lead to early coke charring the composition of the combustion chamber of the parts surface, reducing the combustion chamber volume, changing the compression ratio and work performance. At the same time as many hot spots coke, easily induced early
