Problems solved by technology

[0002] At present, an important reason why the speed of the diesel engine cannot be increased is that it cannot be cooled in time, and the cooling effect of the conventional air cooling method is not obvious enough. When the speed of the diesel engine reaches 3600 revolutions per minute, its temperature is too high, which not only greatly affects the The service life of the diesel engine is shortened, and its fuel consumption is greatly increased. At the same time, insufficient combustion of diesel will result in the emission of a large amount of harmful gases, which is not conducive to environmental protection.

Abstract

The invention relates to a dual-cooled diesel engine. The diesel engine comprises a tank body (2) and a cylinder barrel (1) connected to the top of the tank body (2), wherein the cylinder barrel (1) comprises a cylinder sleeve (1.1) and radiating fins (1.2) sleeved on the cylinder sleeve (1.1); the outer wall of the cylinder sleeve (1.1) is provided with a cooling water jacket (3); a water inlet and a water outlet are formed on the cooling water jacket (3); the radiating fins (1.2) are partitioned into two parts by using the cooling water jacket (3); a part of the radiating fins are positioned in the cooling water jacket (3); and the other part of the radiating fins are positioned outside the cooling water jacket (3). The dual-cooled diesel engine has a remarkable cooling effect.

Description

technical field [0001] The present invention relates to a diesel engine, in particular to a diesel engine that can be cooled by air cooling and water cooling at the same time. on a twin cylinder diesel engine. Background technique [0002] At present, an important reason why the speed of the diesel engine cannot be increased is that it cannot be cooled in time, and the cooling effect of the conventional air cooling method is not obvious enough. When the speed of the diesel engine reaches 3600 revolutions per minute, its temperature is too high, which not only greatly affects the The service life of the diesel engine is shortened, and its fuel consumption is greatly increased. At the same time, insufficient combustion of diesel will result in the emission of a large amount of harmful gases, which is not conducive to environmental protection. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages and provide a dual coo...
