Description

Diesel internal combustion engine body

Technical Field

The utility model relates to an internal-combustion engine organism technical field specifically is a diesel internal-combustion engine organism.

Background

The internal combustion engine is a power source widely used at present, and the device can effectively convert chemical energy stored in combustible materials into mechanical energy, and particularly can effectively convert chemical energy contained in gasoline, diesel oil and the like into mechanical energy. In order to reduce the wall temperature of a combustion chamber of an engine, improve the power per liter of the engine and improve the emission performance of the engine, the existing diesel engine basically adopts a water cooling structure. The water-cooled engine is provided with cooling water jackets in a cylinder cover and a cylinder body, a water pump drives cooling liquid to circularly flow in the engine and a heat dissipation system so as to cool the engine, and meanwhile, a thermostat is arranged in the cooling system and engine oil is cooled. The cylinder sleeve has lateral supports only at the upper part and the bottom part, and most side wall positions in the middle of the cylinder sleeve are in a suspension state. Because the cylinder sleeve contains reciprocating components such as a piston or a dynamic balance slide block and the like, the components can generate side pressure to the side wall in high-speed reciprocating motion; especially, when the reciprocating motion is reversed, the reciprocating motion element can fall from one side of the joint to the other side of the joint in the running track to generate a 'slapping' effect on the side wall of the track, and the side wall of the cylinder sleeve is suspended in the middle, so that the part is easy to deform due to slapping, a reciprocating motion guide rail of a piston is damaged after a long time, and the space of a combustion chamber deforms. The reciprocating motion of the piston and the combustion effect of the combustion chamber are affected.

Most of the existing engines are of multi-cylinder structures, but due to the difference of distances between the cylinders arranged in front and back and the water pump, the difference of flow rates of cooling water flowing through the cylinders is large, poor cooling is caused, particularly, the cooling water is close to a high-temperature area at the upper end, so that the temperature of the cylinder structure is too high, the cylinder structure generates thermal deformation and further generates large thermal strain, the strength and the service life of the cylinder body are reduced, and once the cylinder sleeve is worn, the whole engine body needs to be replaced, and the existing engines have the defect of high maintenance and use cost.
