Background technology
Petrol engine PCV (positive crankcase ventilation (PCV)) valve action：Gas blowby in crankcase is through gs-oil separator or cylinder
Housing carries out Oil-gas Separation, and the gas after separation enters in inlet manifold through Pcv valve, mixed with fresh air, then enters hair
It burns again the combustion chamber of motivation.Pcv valve plays adjusting gas flow, control by the movement of its internal spring and spool
Air-flow one-way flow processed while preventing gas from reversely scurrying into the effect of crankcase.
At present on petrol engine, typically Pcv valve is mounted on the outside of gs-oil separator or valve mechanism cover, then led to
It crosses external pipeline Pcv valve is connected with the nozzle in inlet manifold, the crank case gases after separation is thus introduced into air inlet
Manifold.The common mounting means of Pcv valve has rubber plug type, screw-type, buckle-type；Also have small part by the partial shell of Pcv valve with
Gs-oil separator or cylinder head cover body are made of one, i.e., gs-oil separator or cylinder head cover body serve as Pcv valve partial shell
Function, then spring, spool are assembled as the independent exploitation and composition of sub- part with gs-oil separator or cylinder head cover body.
The frame mode of external Pcv valve need to be in Pcv valve and gs-oil separator or gas such as rubber plug type, screw-type, buckle-type
Using the leakproofness that sealing ring, guarantee are between the two between cylinder head cover, additional external pipeline need to be used and be got over apart from inlet manifold
Far, required pipeline is longer, increases the cost of external pipeline, and can occupy the space layout of enging cabin.
And the partial shell of small part Pcv valve is made of one with gs-oil separator or cylinder head cover body, spring, spool are made
This frame mode that need to be individually developed for sub- part and then be assembled, welded with gs-oil separator or cylinder head cover body
Although sealing ring need not be used, to gs-oil separator or cylinder head cover body, spring, the dimensional accuracy of spool, assembly precision
It is required that high, and need it is fully-integrated after could detect the flow pressure value of Pcv valve and whether reach target, this mode needs again
The structure size factor of point control is more, can influence yield rate.
Utility model content
The utility model aims to solve the problem that the above problem, provides a kind of structure being internally integrated Pcv valve, its Pcv valve
It is internally integrated by Vibration welding and the realization of gs-oil separator ontology, on the one hand, sealing ring and external pipeline need not be used,
Integrated level is high, reduces number of parts, avoids exterior Pcv valve that from need to increasing sealing ring and additional external pipeline and occupies engine
The space layout problem in cabin, keeps the arrangement of enging cabin more compact, and Pcv valve is fabricated separately as individual sub-unit part
Easily detection, quality management and control, in another aspect, the axis direction of Pcv valve is set as consistent with the Z-direction of engine cylinder body, after making separation
Crank case gases can smoothly enter into inside engine cylinder body, at the same also ensure that shutdown after machine oil can smoothly flow back under the effect of gravity
To Oil-gas Separation intracavitary without accumulating in inner passage, the technical solution used is as follows：
A kind of structure being internally integrated Pcv valve, which is characterized in that including:Engine cylinder body, gs-oil separator ontology and
The air inlet of Pcv valve, the Pcv valve is located in the oil-gas separation chamber of gs-oil separator ontology, the gas outlet end face of the Pcv valve
Equipped with the second solderable contact surface, the gs-oil separator ontology has the first solderable contact surface, and the gas outlet of the Pcv valve passes through
Vibration friction welding (FW) between first solderable contact surface and the second solderable contact surface be connected together with gs-oil separator ontology and with
First inner passage of gs-oil separator ontology is connected, the first inner passage of the gs-oil separator ontology and engine cylinder
Second inner passage of body is connected, and the second inner passage of the engine cylinder body is connected with inlet manifold, the Pcv valve
In gs-oil separator ontology.
The beneficial effects of the utility model are：Pcv valve is realized internal by Vibration welding and gs-oil separator ontology
It is integrated, it is not necessary to use sealing ring and external pipeline, integrated level is high, reduces number of parts, avoids exterior Pcv valve that from need to increasing sealing
Circle and additional external pipeline and the space layout problem for occupying enging cabin, keep the arrangement of enging cabin more compact, Pcv valve
As individual sub-unit part, easily detection, quality management and control is fabricated separately, the axis direction of Pcv valve is set as and engine cylinder body
Z-direction it is consistent, so that the crank case gases after separation is can smoothly enter into inside engine cylinder body, at the same also ensure that shutdown after machine oil weight
Oil-gas Separation intracavitary can be smoothly flowed back under force effect without accumulating in inner passage.
