Abstract
The utility model discloses an engine cylinder block, including the body be equipped with a set of combustion chamber on the body bilateral symmetry position respectively, arbitrary adjacent two all be equipped with an inlet opening between the combustion chamber the outside of the combustion chamber of body both sides also all is equipped with an inlet opening, every the inlet opening all runs through the body. The utility model discloses an advantage: because consequently this each internal cooling water course mutual isolation and mutual independence makes the whole volume of the cooling water course of the mutual intercommunication of whole volume ratio of the cooling water course of body less than normal, when the preparation body, because the whole volume of cooling water course is less than normal, just under the circumstances that satisfies engine cylinder block rigidity, can make the wall thickness setting value of body also less than normal to can alleviate the volume weight of body betterly.
Description
Technical field
This utility model relates to technical field of automobile engine, particularly relates to a kind of engine cylinder-body.
Background technology
Electromotor is in the course of the work, have substantial amounts of heat to produce, it is thus desirable to engine cylinder-body is cooled down, the type of cooling now used is that cooling water pressure is entered the cooling water system of cylinder body and cylinder cap by water pump, cooling water pump is placed in the outside of cylinder body, and therefore, the outlet of cooling water pump to connect with the water inlet of cylinder body, cooling water can enter in the cooling water cavity of cylinder body or cylinder cap by water inlet, to realize the purpose of cooling cylinder body and cylinder cap.
At present, cooling water channel in engine cylinder body adopts combination core casting, wherein this combination core is by being connected the overall structure formed between each core monomer by cantilever, therefore, each cooling water channel in engine cylinder body is interconnected, but the cooling water channel overall volume of this connection is relatively larger, and engine cylinder-body and cooling water channel are integrated casting, therefore when making engine cylinder-body, owing to the volume ratio of cooling water channel is looser, and in order to ensure the rigidity of engine cylinder-body, the wall thickness setting value making engine cylinder-body is bigger, so that the volume weight of engine cylinder-body is laid particular stress on.
Utility model content
The purpose of this utility model is to solve the shortcoming existed in prior art, and a kind of engine cylinder-body proposed.
To achieve these goals, this utility model adopts the technical scheme that
A kind of engine cylinder-body, including body, described body lateral symmetry position is respectively equipped with one group of combustor, it is characterized in that: between two described combustor of arbitrary neighborhood, be equipped with an inlet opening, also be equipped with an inlet opening in the outside of the combustor of described body both sides, described body is all run through in each described inlet opening.
Preferably, a division board it is equipped with between two described combustor of arbitrary neighborhood, also being equipped with a division board in the outside of the combustor of described body both sides, two described division boards of arbitrary neighborhood become independent closing space corresponding described combustion chamber isolated.
Preferably, each described inlet opening is arranged at the downside of corresponding described division board.
Preferably, the upper end of each described inlet opening is equipped with a boss, and described boss is provided with the through hole connected with described inlet opening.
The utility model has the advantage of: owing to each cooling water channel intrinsic is mutually isolated and separate, therefore the overall volume making the cooling water channel of body is less than normal than the overall volume of the cooling water channel being interconnected, when making body, owing to the overall volume of cooling water channel is less than normal, and when meeting engine cylinder-body rigidity, the wall thickness setting value that can make body is also less than normal, such that it is able to alleviate the volume weight of body preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of engine cylinder-body provided by the utility model.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain this utility model, be not used to limit this utility model.
As shown in Figure 1, a kind of engine cylinder-body that this utility model provides, including body 1, described body 1 is V-structure, the lateral symmetry position of body 1 is respectively equipped with one group of combustor 2, being equipped with a division board 4 between two described combustor 2 of arbitrary neighborhood, be also equipped with a division board 4 in the outside of the combustor 2 of described body 1 both sides, the corresponding described combustor 2 of two described division boards 4 of arbitrary neighborhood is isolated into independent closing space.
Between the described combustor 2 being arranged symmetrically with, it is respectively provided with a transitional slope 7, described transitional slope 7 is technique slope, it is easy to the demoulding when casting, on the slope of each transitional slope 7, it is equipped with one group of inlet opening 3 straight up, described body 1 is all run through in each described inlet opening 3, and each described inlet opening 3 is arranged at the downside of corresponding described division board 4, it brings and provides the benefit that, owing to each inlet opening 3 in body 1 is mutually isolated and separate, therefore make body 1 overall volume less than normal than the overall volume of cooling water channel being interconnected, when making body 1, owing to the overall volume of inlet opening 3 is less than normal, and when meeting engine cylinder-body rigidity, the wall thickness setting value that can make body 1 is also less than normal, such that it is able to alleviate the volume weight of body 1 preferably.
It is equipped with a boss 5 in the upper end of each described inlet opening 3, described boss 5 is cylindrical structural, owing to cylindrical structural has arc-shaped transitional surface, which improves the intensity of foundry goods, not easy fracture, be additionally provided with a through hole 6 on the surface of described boss 5, described through hole 6 connects with inlet opening 3, for connecting external water inlet pipe.
