Problems solved by technology

[0002] At present, the water inlet of the engine body of the diesel engine is generally a long hole structure, such as figure 2 , this structure has the following defects: 1. When the cylinder center distance remains unchanged, the cylinder diameter is limited; 2. The cylinder deformation is large, the fuel consumption increases, and the diesel engine emission level is difficult to improve; 3. The cylinder deformation is large, and the cylinder liner is early Increased aftermarket failure rate for wear and tear

Embodiment Construction

[0014] In order to further understand the invention content, characteristics and effects of the present invention, the following examples are given, and detailed descriptions are as follows in conjunction with the accompanying drawings:

[0015] see figure 1 with figure 2 , an improved structure of the water inlet of a diesel engine body, including a cylinder block 1, several cylinder barrels 2 arranged on the cylinder block, adjacent cylinder barrels are separated by cylinder barrel walls 3, and the cylinder barrel walls are provided with A water hole 4 is arranged, and a supporting rib 5 is horizontally arranged in the water hole. There are 1 to 3 support ribs along the length direction of the water hole, preferably 2 in this embodiment. The support ribs are cast integrally with the cylinder wall.

[0016] In this way, under the condition that the cylinder center distance remains unchanged, the cylinder diameter can be appropriately increased; at the same time, the cylin...

Abstract

The invention relates to an improved structure of a water opening of a diesel engine body. The improved structure of the water opening of the diesel engine body comprises a cylinder body, wherein a plurality of cylinder barrels are arranged on the cylinder body, every two adjacent cylinder barrels are separated through a cylinder barrel wall, and water holes are formed in the cylinder barrel walls. The improved structure of the water opening of the diesel engine body is characterized in that supporting ribs are transversely arranged in the water opening. In this way, the cylinder diameter can be increased properly under the condition that the cylinder center distance is not changed. Meanwhile, the improved structure of the water opening of the diesel engine body has the advantages that deformation of the cylinder barrels is reduced, machine oil consumption is reduced, and the emission level of a diesel engine is increased; and since deformation of the cylinder barrels is small, the rate of after-sale failures caused by early-stage abrasion of cylinder sleeves is decreased.

Description

technical field [0001] The invention belongs to the technical field of a diesel motor engine body, and in particular relates to an improved structure of a water inlet of a diesel engine body. Background technique [0002] At present, the water inlet of the engine body of the diesel engine is generally a long hole structure, such as figure 2 , this structure has the following defects: 1. When the cylinder center distance remains unchanged, the cylinder diameter is limited; 2. The cylinder deformation is large, the fuel consumption increases, and the diesel engine emission level is difficult to improve; 3. The cylinder deformation is large, and the cylinder liner is early Increased aftermarket failure rates for wear and tear. Contents of the invention [0003] In order to solve the technical problems in the known technology, the present invention provides an improved structure of a water outlet of a diesel engine body with enlarged cylinder diameter, improved displacement, ...
