Abstract
The invention discloses a kind of multi-cylinder air cylinder body water jacket, it is located in cylinder block and each block jacket is communicating together, each block jacket is communicated with by cylinder cap filling pipe end with corresponding cylinder head jacket, it is characterized in that, described cylinder block is provided with body water intake, described body water intake and this multi-cylinder air cylinder body water jacket are connected, and are provided with water-stop sheet in described body water inlet.This multi-cylinder air cylinder body water jacket structure makes the cooling liquid flowing through every block jacket and cylinder head jacket corresponding with it even, and cooling effect is obvious, and meanwhile, cooling liquid can not be impacted the first cylinder liner, avoids the cavitation problems of the first cylinder liner.
Description
Technical field
The present invention relates to cylinder field, particularly a kind of multi-cylinder air cylinder body water jacket.
Background technique
Block jacket to be engine interior be engine hot parts the lowers the temperature cooling water circulation passage designed, cooling liquid reaches the effect of heat radiation at water jacket Inner eycle, the circulation tool of structure to cooling liquid of water jacket has a great impact, general engine coolant endless form is: first, pump handle cooling liquid is pressed into from the water intake of cylinder block front end, direct ingress engine oil cooler, is cooled machine oil by the radiating fin of machine oil cooler.Then, cooling liquid cools cylinder block and head, and when cooling cylinder block, cooling liquid enters multi-cylinder air cylinder body water jacket by the water intake on body, and the water intake on body is generally one; When cooling cylinder head, the cooling liquid in cylinder block enters cylinder head jacket by the cylinder cap filling pipe end of cylinder block and cylinder head, and every cylinder has cylinder cap filling pipe end.
In technique scheme, after cooling liquid enters multi-cylinder air cylinder body water jacket by the water intake on body, first cooling is near the cylinder of water intake, cool other cylinder more in order, in the process of this liquid circulation, when not having to cool cylinder below, part cooling liquid directly enters cylinder head jacket, the cooling liquid of the cylinder flowed through rearward can be caused so fewer than forward cylinder, and coolant rate is uneven, and cooling effect is bad.Meanwhile, water intake is just to the cylinder sleeve of first cylinder, and cooling liquid is impacted the cylinder sleeve of this cylinder always, is easy to the cavitation pitting causing this cylinder cylinder sleeve.
Summary of the invention
The present invention is to overcome defect in above-mentioned prior art, provides a kind of multi-cylinder air cylinder body water jacket, and make the cooling liquid flowing through every cylinder water jacket even, good cooling results, meanwhile, the cylinder sleeve of first cylinder cavitation erosion can not occur.
For achieving the above object, the invention provides a kind of multi-cylinder air cylinder body water jacket, it is located in cylinder block and each block jacket is communicating together, each block jacket is communicated with by cylinder cap filling pipe end with corresponding cylinder head jacket, cylinder block is provided with body water intake, body water intake and this multi-cylinder air cylinder body water jacket are connected, and are provided with water-stop sheet in body water inlet.
In technique scheme, water-stop sheet and cylinder liner integrally casting shaping.
Compared with prior art, the beneficial effect that the present invention has is: shunt and leading role cooling liquid by arranging water-stop sheet, make the cooling liquid flowing through every block jacket and cylinder head jacket corresponding with it even, cooling effect is obvious, simultaneously, cooling liquid can not be impacted the first cylinder liner, avoids the cavitation problems of the first cylinder liner.
Accompanying drawing explanation
Fig. 1 is multi-cylinder air cylinder body water jacket structural representation of the present invention;
Fig. 2 is block jacket and cylinder head jacket connection diagram in the present invention.
Mark the following drawings mark thereon by reference to the accompanying drawings:
1-water intake, 2-water-stop sheet, 3-first block jacket, 4-head gasket, 5-cylinder cap filling pipe end, 6-cylinder cover water jacket.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention not by the restriction of embodiment.
As shown in Figure 1, multi-cylinder air cylinder body water jacket of the present invention mainly arranges water-stop sheet 2 at body water intake 1 place, water-stop sheet 2 is one-body molded by casting and cylinder sleeve, water-stop sheet 2 is shunted the cooling liquid entering cylinder block, distribute the flow of cooling liquid in multi-cylinder water jacket according to this, reach cooling liquid being uniformly distributed in multi-cylinder water jacket, improve simple, but cooling effect significantly improves.
As shown in Figure 2, multi-cylinder cylinder block in the present embodiment, comprise the first block jacket 3, block jacket and cylinder cover water jacket 6 are by cylinder cap filling pipe end 5 UNICOM, and every cylinder block jacket and cylinder cover water jacket one_to_one corresponding UNICOM, be provided with head gasket 4 between cylinder block and cylinder head, cooling liquid is circulation time in water jacket, first through block jacket, then enter cylinder head from cylinder cap filling pipe end 5, cylinder head is cooled.
When there is not radical change in existing block structure, the size of body water intake 1 is changeless, after water pump applies certain pressure to cooling liquid, the distribution of cooling liquid is regulated to be necessary by arranging water-stop sheet 2, otherwise, a large amount of cooling liquids enters the first block jacket 3, the cooling liquid flowing through other block jacket (unmarked in figure) is caused to tail off like this, and every cylinder block jacket only circulates up and down with corresponding cylinder head jacket, nature, the cooling liquid flowing through the cylinder head jacket (in figure unmarked) corresponding with other block jacket also reduces, so, at whole cylinder cooling segment, the cooling effect of other cylinder block part and the cylinder head portion corresponding with other cylinder block part is just weakened.
Water-stop sheet in the present embodiment 2 pairs of cooling liquids can also play the effect of water conservancy diversion while shunting, like this, avoid the impact of cooling liquid to the first cylinder cylinder sleeve, cavitation erosion can not occur.
Be only specific embodiments of the invention above, but the present invention is not limited thereto, the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
Claims (2)
