Background technique
The cylinder body water jacket of engine water intake is arranged in front end, and when cooling water, from the cylinder body water jacket front end flows to the cylinder body water jacket rear end, the cooling water pressure of cylinder body water jacket and flow descend, and cause the cooling deficiency in cylinder body water jacket rear end; Cylinder cap exhaust side valve seat ridge area is because near engine chamber, thus be the highest zone of temperature in cylinder cap, and on traditional Designing of Body Water-Jacket, the cooling effect of cylinder cap exhaust side valve seat ridge area is poor, easily causes the appearance of cylinder cap problems of crack.How to improve the whole cooling effect of cylinder body water jacket and, to the cooling effect of cylinder cap exhaust side valve seat ridge area, be the problem that those skilled in the art are making great efforts always.
The model utility content
The purpose of this utility model aims to provide a kind of cylinder body water jacket of engine, and these cylinder body water jacket intake and exhaust side current are even, and cylinder body water jacket front end and back end current pressure reduction is less, and cylinder body water jacket is cooling evenly, good cooling results.
The utility model is achieved through the following technical solutions:
A kind of cylinder body water jacket of engine, be provided with water intake at cylinder body exhaust side front end, at the exhaust side of cylinder body, is provided with water hole on four cylinder caps, and the exhaust side of cylinder body is furnished with the EGR coolant outlet; On described cylinder cap, water hole is communicated with cylinder cover water jacket delivery valve seat ridge area.
In the cylinder body water jacket arranged around, 6 sand cleaning hole lugs are arranged, wherein in the front-end and back-end of cylinder body, respectively be furnished with 1 sand cleaning hole lug, at exhaust side and air inlet side, respectively be furnished with 2 sand cleaning hole lugs.
Respectively be furnished with one for the cooling cylinder body water jacket coolant outlet of engine EGR on the sand cleaning hole lug of air inlet side and exhaust side and be the cooling cylinder body water jacket coolant outlet of oil filter.
The beneficial effects of the utility model are:
This water jacket adopts exhaust side near the front end water inlet, at the water jacket exhaust side, increases water hole on 4 cylinder caps, and cylinder body water jacket can provide cooling water for engine EGR and oil filter simultaneously.These cylinder body water jacket intake and exhaust side current are even, and cylinder body water jacket front end and back end current pressure reduction is less, and cylinder body water jacket is cooling evenly, good cooling results.

Embodiment
Below describe the technical solution of the utility model in detail by specific embodiment, should be understood that, following embodiment is only exemplary, only can be used for explaining and the explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
In the technological scheme of the present embodiment, the common four cylinder engine of take describes as example.
A kind of cylinder body water jacket of engine, be provided with water intake at cylinder body exhaust side front end, the cylinder body water jacket water intake is arranged in the cylinder body exhaust side, being arranged in the cylinder body front end with the cylinder body water jacket water intake compares, being conducive to increase front end utilizes space on the one hand, avoids the cylinder bolt hole of cylinder body front end not take root fully; Make on the other hand current flow to the cylinder body water jacket rear end along intake and exhaust side both direction, increase the water flow of cylinder body water jacket rear end, increase the exchange capability of heat of cylinder body water jacket simultaneously.
Exhaust side at cylinder body is provided with water hole on four cylinder caps, and on cylinder cap, water hole is communicated with cylinder cover water jacket delivery valve seat ridge area.This water jacket increases water hole on 4 cylinder caps at exhaust side, be that cooling liquid water hole from 4 cylinder caps in cylinder body water jacket enters cylinder cover water jacket delivery valve seat ridge area, increase the water flow of cylinder cap delivery valve seat ridge area, solve the cooling overheated problem of cylinder cap delivery valve seat ridge area existed in prior art, it is simple in structure, and function is easy to realize.
In the cylinder body water jacket arranged around, 6 sand cleaning hole lugs are arranged, wherein in the front-end and back-end of cylinder body, respectively be furnished with 1 sand cleaning hole lug, at exhaust side and air inlet side, respectively be furnished with 2 sand cleaning hole lugs.Respectively be furnished with one for the cooling cylinder body water jacket coolant outlet of engine EGR on the sand cleaning hole lug of air inlet side and exhaust side and be the cooling cylinder body water jacket coolant outlet of oil filter.
Shown in figure 1 and Fig. 2, Fig. 1 and Fig. 2 are that the axle of the utility model cylinder body water jacket measures intention, arrange water hole 2 on 4 cylinder caps on cylinder body water jacket 1, cylinder body water jacket exhaust side arranging EGR coolant outlet 3 and cylinder body water jacket water intake 4, cylinder body water jacket air inlet side is arranged sand cleaning hole 5 and 6, and wherein sand cleaning hole 6 is the engine oil filter coolant outlet.
Shown in figure 3, Fig. 3 is cylinder body water jacket flow schematic diagram of the present utility model, cooling water is divided into two-part from cylinder body water jacket water intake 4 enters cylinder body water jacket, part cooling water flows to cylinder body water jacket rear end 10 from cylinder body water jacket front end 8 along air inlet side 9, another part directly flows to cylinder body water jacket rear end 10 along cylinder body water jacket exhaust side 7, two-part cooling water finally converges in cylinder body water jacket rear end 10, increase like this water flow of cylinder body water jacket rear end 10, strengthened the cooling effect of cylinder body water jacket rear end 10.
Shown in figure 4, Fig. 4 is the water flow schematic diagram of installing after cylinder cover water jacket, cooling water from the cylinder body water jacket exhaust side along 4 cylinder cover water jackets water hole enter the cylinder cap delivery valve seat ridge area in cylinder cover water jacket 11, strengthen the cooling effect of ridge area.
Shown in figure 5, the water intake of cylinder body water jacket is arranged in the cylinder body front end, causes the front terminal bolt 12 of cylinder body not taken root.
Although illustrated and described embodiment of the present utility model, for the ordinary skill in the art, be appreciated that in the situation that do not break away from principle of the present utility model and spirit can be carried out multiple variation, modification, replacement and modification to these embodiments, scope of the present utility model is by claims and be equal to and limit.
