Abstract
The utility model discloses a cylinder of a diesel engine, which comprises a cylinder body; a cooling channel is arranged in the cylinder body; an inlet of the cooling channel is arranged on a pump installation plane of the cylinder body; an outlet of the cooling channel is arranged on the top surface of the cylinder body and is communicated with the waterway of a cylinder cover of the diesel engine. A baffle is arranged in the cooling channel. The cylinder has a simple structure and can improve the thermal efficiency of the diesel engine.
Description
Technical field
The utility model relates to a kind of cylinder of diesel engine, relates in particular to a kind of band cooling water channel cylinder of diesel engine.
Background technique
At present, the cooling water channel of domestic conventional diesel engine all is to enter cylinder block through water pump; Enter cylinder head by cylinder block; Flow out from cylinder head again,, enter water pump again and form the circulatory system of cooling liquid through cooling water tank.This tradition cooling tape loop has been walked the sizable heat of cylinder block.Reduced the thermal efficiency of diesel engine; And the cooling liquid of whole system is all passed through cylinder block, has formed pressure and has fallen, and needs water pump to overcome, so water pump needs enough big lift, has also reduced the thermal efficiency of diesel engine.
Summary of the invention
Technical problem to be solved in the utility model is the defective that overcomes prior art, provides a kind of simple in structure, can improve the cylinder of diesel engine of the thermal efficiency of diesel engine.
For solving the problems of the technologies described above, the utility model provides a kind of cylinder of diesel engine, comprise the cylinder block body, in described cylinder block body, offer cooling passage, the import of described cooling passage is opened in the water pump attachment face of described cylinder block body, and the outlet of described cooling passage is opened in the end face of described cylinder block body and is connected with the cylinder head water route of diesel engine.
In described cooling passage, be provided with dividing plate.Dividing plate pro-rata part cooling liquid is by this special cooling passage.
Owing to adopt above-mentioned technological scheme, the utlity model has following beneficial effect:
1, can reduce the cylinder barrel heat on every side that cooling liquid is taken away, thereby the thermal efficiency of diesel engine is provided;
2, can reduce the lift of water pump, thereby improve the thermal efficiency of motor.
Description of drawings
Fig. 1 is the sectional view of the utility model cylinder of diesel engine.
The end face view of Fig. 2 the utility model cylinder of diesel engine.
The lateral plan of Fig. 3 the utility model cylinder of diesel engine.
Mark the following drawings mark thereon in conjunction with the accompanying drawings:
1-cylinder barrel outer wall; 2-cylinder block body; The 3-cooling passage; The 4-dividing plate; The 5-end face;
The outlet of 6-cooling passage; The import of 7-cooling passage; 8-water pump attachment face.
Embodiment
Below in conjunction with accompanying drawing embodiment is illustrated:
As Fig. 1, Fig. 2, shown in Figure 3, the utility model cylinder of diesel engine, comprise cylinder barrel outer wall 1, cylinder block body 2, in cylinder block body 2, offer cooling passage 3, this cooling passage import 7 is opened in the water pump attachment face 8 of cylinder block body 2, and cooling passage outlet 6 is opened in the end face 5 of cylinder block body 2 and is connected with the cylinder head water route of diesel engine.
In use, from the next cooling liquid of water pump, pass through cooling passage 3 by dividing plate 4 pro-rata part cooling liquids, and other a part of cooling liquid is by transmission cooling line cycle, because this part cooling liquid does not directly enter the cylinder head cooling water road through cylinder block, so the heat that cooling liquid is taken away reduces; This part cooling liquid does not directly enter the cylinder head cooling water road through cylinder block, so cylinder block reduces to the total pressure reduction of cylinder cap water outlet is just corresponding, the needed lift of water pump decreases, thereby has also improved the thermal efficiency of motor
It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of spirit and scope of the present utility model, and it all should be encompassed in the claim scope of the present utility model.
Claims (2)
1, a kind of cylinder of diesel engine, comprise the cylinder block body, it is characterized in that: in described cylinder block body, offer cooling passage, the import of described cooling passage is opened in the water pump attachment face of described cylinder block body, and the outlet of described cooling passage is opened in the end face of described cylinder block body and is connected with the cylinder head water route of diesel engine.
2, cylinder of diesel engine according to claim 1 is characterized in that: be provided with dividing plate in described cooling passage.
