Abstract

The invention relates to an oil cooling type diesel engine. The oil cooling type diesel engine comprises an engine body, a cylinder sleeve and a cylinder head. The engine body is provided with an oil storing cavity. The periphery of the cylinder sleeve is provided with an oil cooling sleeve. A cooling oil passage way A and a cooling oil pump are arranged between the outlet end of the oil storing cavity and the inlet end of the oil cooling sleeve. The cylinder head is provided with a cooling oil passage way B. The inlet end of the cooling oil passage way B is connected with the outlet end of the oil cooling sleeve. The outlet end of the cooling oil passage way B is connected with the inlet end of an external oil pipe. The outlet end of the oil pipe is connected with the inlet end of the oil storing cavity. The purpose of the oil cooling type diesel engine is to provide an oil cooling type diesel engine with the simple structure and good cooling effect. The oil cooling type diesel engine has the advantages that first, due to the fact that a cooling system and a lubricating system share one oil storing cavity, the structure of the diesel engine is simplified, the manufacturing cost is lowered, and the cooling effect is improved; second, by arranging an oil cooler on the oil pipe, the cooling of heated cooling liquid is accelerated, and the optimal-state operation of the whole cooling system is guaranteed.

Description

technical field [0001] The invention relates to a diesel engine, in particular to an oil-cooled diesel engine. Background technique [0002] Diesel engine operating temperature is too high or too low will reduce its power and economy. The role of the cooling system is to keep the diesel engine working at the most suitable temperature to obtain good economy, power and durability. The existing cooling system can be divided into air cooling and water cooling according to different cooling media. The air-cooled diesel engine is simple in structure and small in size. Compared with the water-cooled diesel engine, it reduces parts, simplifies the structure, simplifies the production process, and reduces the production cost; the water-cooled diesel engine cools evenly and has a good cooling effect, and the noise generated Much smaller than air-cooled diesel engines. [0003] When the diesel engine is working in an environment with high temperature or poor ventilation, the cooling...
