Description
Technical field
The utility model is related to a kind of cylinder cap, belongs to automotive engine applications.
Background technology
The PCV main functions of petrol engine are that the gas in crankcase is imported into inlet manifold by Pcv valve, and PCV can
With the appearance of avoid burning insufficient, deterioration of emission, machine oil the problems such as rotten.At present, it is necessary in addition after gas is by Pcv valve
Realized in disposed outside steam hose and introduce gas into inlet manifold, limited space is occupied significantly, while adding into
This.
The content of the invention
The utility model purpose is to propose a kind of cylinder cap of integrated PCV passage, can be turned when installing EGR valve with EGR valve
Joint chair carries out transition connection, both meets the operability of assembling EGR valve, and does not increase external engine profile overall volume, and
And simple in construction, easy maintenance.
The utility model proposes a kind of cylinder cap of integrated PCV passage.
Above-mentioned purpose is realized, the technical scheme that the utility model is taken is as follows：
A kind of cylinder cap of integrated PCV passage, including：PCV pipelines, steel ball, exhaust piping, inlet channel, gas off-take and cylinder
Lid body；The entrance of described PCV pipelines is arranged on cylinder cap body top, the outlet of PCV pipelines and the entrance phase of exhaust piping
Logical, the outlet of described discarded pipe with inlet channel is communicated, and is pressed with steel ball at the import of described inlet channel, is discarded pipe
Inlet communication of the outlet in road through gas off-take and inlet manifold, the described outlet of inlet manifold and the entrance of inlet channel connects
Logical, PCV pipelines, exhaust piping, inlet channel and gas off-take are arranged at cylinder cap body interior.
The utility model is relative to the beneficial effect of prior art：
The utility model proposes a kind of cylinder cap of integrated PCV passage, by PCV pipelines, exhaust piping, inlet channel and go out
Air flue is arranged at cylinder cap body interior, and motor mechanisms can be made compacter, and being arranged on outside cylinder cap before saving
Steam hose, the workload of assembling with cost-effective, can be reduced, make engine structure compacter.

6 tops, the outlet of PCV pipelines 1 is communicated with the entrance of exhaust piping 3, the outlet phase of described discarded pipe 3 and inlet channel 4
It is logical, be pressed with steel ball 2 (guarantee air-tightness) at the import of described inlet channel 4, the outlet of discarded pipe 3 through gas off-take 5 with
The inlet communication of inlet manifold, the outlet of described inlet manifold is connected with the entrance of inlet channel 4, PCV pipelines 1, flue gas leading
Road 3, inlet channel 4 and gas off-take 5 are arranged inside cylinder cap body 6.
Embodiment two：Illustrate with reference to Fig. 1 ~ Fig. 3, a kind of integrated PCV passage described in embodiment one
Cylinder cap, described PCV pipelines 1, exhaust piping 3, inlet channel 4 and gas off-take 5 is integrated in cylinder cap body 6 using machine add mode
It is internal.
The course of work is：Add the entrance of PCV pipelines 1 in the top machine of cylinder cap body 6, the gas Jing Guo Pcv valve is introduced
Into the integrated PCV pipelines 1 of cylinder cap body 6, enter exhaust piping 3 by the waste gas of PCV pipelines 1, then through exhaust piping 3 and go out
Air flue 5 enters inlet manifold, finally comes back to inlet channel 4.Steel ball 2 is pressed with the import of inlet channel 4, it is ensured that gas
Close property.
