1.积碳的危害发动机工作时,润滑油窜入燃烧室与燃油混合使混合气不能全部燃烧,形成羟基酸和树脂状胶质粘附在零件表面上,再经高温作用变成沥青质和油焦质等复杂的混合物即积炭。预燃室启动喷孔聚有积炭,将堵塞喷孔,使发动机启动困难;喷油嘴聚有积炭,极易卡死喷油嘴,造成发动机缺缸运行或熄火;火花塞积炭过多,在燃油湿润后,相当于火花塞电极间并联分路电阻,造成火花塞漏电、跳火过弱,严重时火花塞不能工作;当排气道、排气管消声器内壁积炭严重时,排
1. The hazards of carbon deposition Engine work, the oil fleeing into the combustion chamber and the fuel mixture so that the mixture can not be all the combustion, the formation of hydroxy acids and resin-like gum adhesion to the surface of the parts, and then become the role of high temperature asphaltene and Oil coke and other complex mixture of carbon deposition. Pre-combustion chamber activated nozzle coke accumulation, the plug hole will be blocked, making the engine difficult to start; injector nozzle coke, easily stuck nozzle, causing the engine running or stalling lack of cylinders; spark plug too much coke , After wetting the fuel, it is equivalent to the shunt resistor in parallel between the spark plug electrodes, causing the spark plug to leak electricity. The spark plug is too weak and the spark plug can not work when it is serious. When the inner wall of exhaust pipe and exhaust muffler coke is serious,
