Description
Technical field
The present invention relates to engine component fields, and in particular to a kind of braided channel cylinder head of anti-carbonization of oil.
Background technique
Existing cylinder head ventilation oil back chamber and exhaust duct do not share wall surface mostly, cause air cylinder head structure complicated, occupy
Space is larger；But it is excessively high and lead to machine inside oil back chamber that design oil back chamber and exhaust duct can have exhaust path temperature when sharing wall surface
Therefore the problem of oily coking is lance generally acknowledged in the industry to optimize air cylinder head structure and reduce occupancy volume shared wall surface is arranged
Shield scheme and not use.
Such as the Chinese invention patent " cylinder head " of Publication No. CN104329180A, the air inlet side is equipped with independent lubrication
Oily oil return hole；Lubricating oil return hole one end passes to cylinder lid top panel, and the other end passes to cylinder head bottom surface；The cylinder caping
Plate formed stepwise, the top plate portion around the push-rod hole are higher than other parts.Such structure improves cylinder well
The intensity of lid avoids the phenomenon that cylinder head cracks under thermic load, and more lubricating oil is effectively organized to pass through air inlet
Side lubricating oil return hole returns to cylinder head, effectively reduces heating of the exhaust side high temperature to lubricating oil.
As can be seen that the prior art generally considers that evading oil back chamber and exhaust duct shares wall surface, to reduce exhaust side height
Heating of the temperature to lubricating oil；When thus the prior art can not obtain oil back chamber and exhaust duct and share wall surface, the knot of cylinder head is brought
Structure is simple, accounts for small in size and machine oil noncoking technical solution.
Summary of the invention
The purpose of the present invention is to provide a kind of braided channel cylinder head of anti-carbonization of oil, it is intended to solve in the prior art
Oil back chamber and exhaust duct can bring the contradictory problems of carbonization of oil when sharing wall surface.
To realize above-mentioned technical purpose and the technique effect, the invention is realized by the following technical scheme:
The present invention provides a kind of braided channel cylinder head of anti-carbonization of oil, comprising: is arranged in cylinder head and is used for
The exhaust duct and the oil back chamber for machine oil reflux that engine high-temperature exhaust gas is discharged, the exhaust duct and oil back chamber share wall surface,
It is additionally provided with the braided channel for being used to form netted cooling wall in the wall surface, one end of the braided channel and cylinder head
The connection of first water jacket, the other end of braided channel and the second water jacket of cylinder head connect.
Preferably, the braided channel is made of the first cylindricality water channel and the second cylindricality water channel, the first cylindricality water channel
And second pass through through-hole between cylindricality water channel and be connected to.
Preferably, at least three through-hole is provided between the first cylindricality water channel and the second cylindricality water channel.
Preferably, the braided channel passes through casting and forming.
Advantages of the present invention:
1. exhaust duct and oil back chamber share wall surface in the present invention, so that the compact occupancy of air cylinder head structure is small in size.
2. using braided channel in the present invention, film-cooled heat can be effectively increased, carbonization of oil is prevented.

Fig. 2 is the structural schematic diagram in the face A-A of Fig. 1；
Fig. 3 is the structural schematic diagram in the face B-B of Fig. 2.
In figure, 100 be cylinder head, and 101 be exhaust duct, and 102 be oil back chamber, and 103 be the first water jacket, and 104 be the second water jacket,
105 be wall surface, and 201 be the first cylindricality water channel, and 202 be the second cylindricality water channel, and 203 be through-hole.
Specific embodiment
In order to make the purpose of the present invention, technical solution and advantage are more clearly understood, and are passed through below in conjunction with attached drawing specific real
Applying example, the present invention is described in more detail.It should be appreciated that described herein, specific examples are only used to explain the present invention, and
It is not used in the restriction present invention.
A kind of braided channel cylinder head of anti-carbonization of oil is provided in the embodiment of the present invention, as shown in Figures 1 to 3, packet
It includes: the exhaust duct 101 for being used to be discharged engine high-temperature exhaust gas (800 DEG C to 900 DEG C) and the machine of being used in cylinder head 100 is set
The oil back chamber 102 of oil reflux, it is compact to obtain that the exhaust duct 101 with oil back chamber 102 shares wall surface 105 (as shown in Figure 3)
Structure design, reduce occupy volume and save cost, be additionally provided in the wall surface 105 and be used to form netted cooling wall
Braided channel 200, braided channel 200 can effectively increase film-cooled heat, promote cooling efficiency, the braided channel 200
One end is connect with the first water jacket 103 of cylinder head 100, the first water jacket 103 for accessing recirculated cooling water, braided channel it is another
End is connect with the second water jacket 104 of cylinder head, and the second water jacket 104 is for being discharged recirculated cooling water.
In one embodiment, as shown in Fig. 2, the braided channel 200 is by the first cylindricality water channel 201 and the second cylindricality water
Road 202 forms, and since 105 space of wall surface is limited, excessive water channel, which is arranged, will affect exhaust efficiency, and water channel can then reduce cold very little
