燃油渗入油底壳内的滑油中,是柴油机工作寿命缩短的原因之一。燃油冲淡润滑油,会使其粘度降低,从而会导致发动机润滑系统压力下降,加速活塞环和轴承的磨损。在某些情况下,甚至可发生拉缸及曲轴轴瓦转动等现象。燃油冲淡柴油机滑油的情况经常发生,尤其在高负荷的拖拉机运行过程中最为常见。根据1988～1984年苏联梁赞地区的调查资料,在功率达73.6kW的柴油机中,有8％使用冲淡的滑油运行,对于T-150K拖拉机用的柴油机来说,则占15％,而在K-700和K701拖拉机用的柴油机中则分别占24％和50％。
Fuel oil infiltration oil pan, the working life of diesel engines is one of the reasons shortened. Fuel Dilution Oil, will reduce its viscosity, which will lead to the pressure drop of the engine lubrication system, accelerate the wear of piston rings and bearings. In some cases, even pull cylinder and crankshaft bearing rotation may occur. Fuel Flush Diesel Engine oil often occurs, especially during high-load tractor operations. According to surveys conducted in the Ryazan region of the Soviet Union from 1988 to 1984, 8% of the diesel engines with a power of 73.6kW were operated with a diluted oil and 15% with a diesel engine used for a T-150K tractor. The diesel engines for K-700 and K701 tractors account for 24% and 50% respectively.
