Embodiment Construction

[0015] Hereinafter, exemplary embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. Although the drawings show exemplary embodiments of the present disclosure, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0016] According to the embodiment of the present invention, an arrangement form of the water cavity of the body is proposed. The cooling system includes a main water inlet 10, first to fourth water inlet holes 11-14 and a connecting pipe 15 for water inlet. The water flows in from the main water inlet and enters the first to fourth water inlets through the circulation pipe respectively. Different from the prior art...

Abstract

The invention provides a machine body water cavity arrangement form. A main water inlet hole and a plurality of branched water inlet holes are included. The number of the water inlet holes is greater than that of air cylinders. The main water inlet hole communicates with the branched water inlet holes through fluid. The machine body water cavity arrangement form is characterized in that the cross sections of the water inlet holes are not completely identical. Through the arrangement, the uniformity of water flowing into all the air cylinders is guaranteed, all the air cylinders are also cooled uniformly correspondingly, existence of dead water zones is avoided, and suspension of cores is avoided, and the strength of sand cores can be enhanced.

Description

Technical field [0001] The invention relates to an engine cooling system, in particular to an engine water distribution cavity. Background technique [0002] In the structure of the diesel engine body, due to structural limitations and the requirements of the layout of the whole machine, the presence or absence of the water jacket and the arrangement of the water cavity are not the same. Generally, if space permits, a section of water distribution chamber is designed before the water inlet jacket, which can stabilize the pressure so that the cooling water enters each cylinder separately. In the prior art, the arrangement of the water distribution chamber is generally one water inlet per tank, such as figure 1 Shown. [0003] For this solution with one water inlet per cylinder, since most of the existing cylinder heads are integral cylinder heads, taking a four-cylinder machine as an example, each of the four cylinders has a water inlet hole, generally at the front end of the cylin...
