Description
Technical field
The utility model relates to technical field of engines, and in particular to a kind of New water jacket structure cylinder cap.
Background technology
Currently, the Temperature Distribution of cylinder cap each section is very uneven when engine combustion, very such as bottom surface combustor section temperature
Height, and the temperature of cooling jacket part is relatively low, inlet and outlet channel temp difference is also very big, therefore, mechanical stress that cylinder cap is born and
Thermal stress is all very big, and combustion chamber and the cooling jacket temperature difference are big, and cooling water circulation effect is poor, and dynamic property, economy, discharge do not reach
Mark, casting cost is high, to solve the above-mentioned problems, it is particularly necessary to design a kind of novel jacket structure for water cylinder cap.
Utility model content
In view of the shortcomings of the prior art, the utility model aims to provide a kind of New water jacket structure cylinders
Lid, simple in structure, reasonable design, compact in design can be organized effectively to cool down flow, avoid generating stress concentration, dynamic property, economy
Property it is good, the feature of environmental protection is high, and casting cost is low, use easy to spread.
To achieve the goals above, the utility model is to realize by the following technical solutions：A kind of new type water noose
Structure cylinder cap, including cylinder cap ontology, water jacket, machine oil cooling jacket, fuel oil cooling jacket, fuel injector and combustion chamber, cylinder cap ontology
It is internally provided with fuel injector and combustion chamber, cylinder cap ontology side is provided with water jacket, and it is cold that organic oil is arranged in the cylinder cap ontology other side
But water jacket, fuel oil cooling jacket, the water jacket are communicated with machine oil cooling jacket, fuel oil cooling jacket respectively.
The beneficial effects of the utility model：Cooling effect is improved, mechanical stress and thermal stress are reduced, it is economical, real
With property, dynamic property higher, the service life is longer, and mitigates weight, substantially reduces cost.
Description of the drawings
It is described in detail the utility model with reference to the accompanying drawings and detailed description；
Fig. 1 is the front view of the utility model cylinder cap；
Fig. 2 is the vertical view of the utility model cylinder cap.
Specific implementation mode
To make the technical means, creative features, achievement of purpose, and effectiveness of the utility model be easy to understand, below
In conjunction with specific implementation mode, the utility model is expanded on further.
Referring to Fig.1-2, present embodiment uses following technical scheme：A kind of New water jacket structure cylinder cap, including cylinder
Lid ontology 1, water jacket 2, machine oil cooling jacket 3, fuel oil cooling jacket 4, fuel injector 5 and combustion chamber 6 are set inside cylinder cap ontology 1
It is equipped with fuel injector 5 and combustion chamber 6,1 side of cylinder cap ontology is provided with water jacket 2, and 1 other side of cylinder cap ontology is arranged organic oil and cools down
Water jacket 3, fuel oil cooling jacket 4, the water jacket 2 are communicated with machine oil cooling jacket 3, fuel oil cooling jacket 4 respectively.
The working principle of this specific embodiment:：Cooling water is flowed by water jacket 2 in cylinder cap ontology 1, to 5 He of fuel injector
Combustion chamber 6 carries out cooling water circulation, makes the reduction of its temperature, and respectively will be cold by machine oil cooling jacket 3, fuel oil cooling jacket 4
But water is discharged.
Present embodiment compact and reasonable arrangement keeps cooling water circulation more abundant, and cylinder head cooling is good, temperature field point
Cloth is uniform, reduces thermal stress, avoids forming crackle between valve seating, can organize effectively to cool down flow and generate
Stress concentration optimizes the design of entering and exhaust channel, to improve dynamic property, the economy of complete machine indirectly by changing the structure of water jacket
And meet increasing emission request；Meanwhile the cylinder cap is by the adjustment of jacket structure for water, the weight saving of entire cylinder head,
The rejection rate and cost of cylinder head blank are reduced, hair has a vast market application prospect so that casting cost reduction.
The advantages of basic principles and main features and the utility model of the utility model have been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the present utility model is not limited to the above embodiments, described in above embodiments and description
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
