Combined type engine oil-blocking heat-insulation structure

The utility model discloses a combined type engine oil-blocking heat-insulation structure. An air cylinder cover of a combined type engine is arranged on an air cylinder cover in a covering mode, a high-pressure oil pipe is distributed on one side of the air cylinder cover, and a diesel oil filter and a supercharger are distributed on the lateral face of the high-pressure oil pipe. The combined type engine oil-blocking heat-insulation structure comprises oil blocking plates, a diesel oil filter heat-insulation cover and a supercharger heat-insulation cover, wherein the oil blocking plates cover the outer side of the high-pressure oil pipe, the diesel oil filter heat-insulation cover covers the outer side of the diesel oil filter, and the supercharger heat-insulation cover covers the outer side of the supercharger. According to the combined type engine oil-blocking heat-insulation structure, the oil blocking plates are distributed among high-temperature components such as the high-pressure oil pipe, the supercharger and air discharge pipes, and heat-insulation covers cover the supercharger and the diesel oil filter, so that fire hazards caused by the fact that the high-pressure oil pipe cracks and oil is spayed on the high-temperature components are prevented, and operation stability of the combined type engine is strengthened.
