Abstract

The application relates to a water jacket structure of an engine, which includes a cylinder block and a cylinder liner; the cylinder liner is arranged in the cylinder block and forms a water jacket with the cylinder block, and the cylinder liner is provided with a sealing ring on the wall surface close to the cylinder block The cylinder liner seal ring groove; and, the cylinder liner is also provided with an arc-shaped diversion port, which is located below the cylinder liner seal ring groove, and is formed by the wall surface of the cylinder liner close to the cylinder block toward the direction away from the cylinder block. . In this application, a diversion port is set under the groove of the cylinder liner seal ring to increase the width of the upper part of the water jacket. The occurrence of erosion phenomenon can ultimately reduce the high maintenance cost of the engine and prolong the service life of the engine; cooling effect.

Description

technical field [0001] The present application relates to the technical field of engines, in particular to a water jacket structure of an engine. Background technique [0002] At present, the diesel engine water jacket structure of the wet cylinder liner provided in the related art comprises a cylinder liner 2 and a cylinder block 1, and a water jacket 3 is formed between the cylinder liner 2 and the cylinder block 1 (as figure 1 As shown), in some related technical solutions, when relevant personnel design the water jacket 3, the cylinder liner 2 directly transitions down from the lower part of the cylinder liner sealing ring groove 4, so that the water jacket 3 is narrow in the upper part and wider in the lower part After long-term use of this water jacket structure, cavitation is likely to occur on the wall surface of the cylinder liner 2 corresponding to the upper part of the water jacket 3, resulting in high engine maintenance costs and shortened engine life. [0003] ...
