Description
Technical field
The utility model is related to engine charge technical fields, more particularly, to a kind of hair that can effectively prevent oil and gas leakage
Motivation gas handling system.
Background technology
Gasoline is volatile gas, for most of Automobile Enterprises, the fuel consumption of automobile and is brought to bad border
Contamination control be very important, in vehicle traveling process or parking after a period of time, more or less have the vapour of part
Oily volatilization gas leakage is in air.
Control and the reasonable most main engine plants now that are utilized as gas leakage solve the problems, such as.At present as shown in figure 3,
It is most of to add canister on the engine, it, may be due to air inlet discrimination after automobile is in suddenly deceleration and parking for adsorbing oil gas
The oil gas of pressure senior general's inlet manifold of pipe 1 channels on canister control valve 5, also there is certain risk of leakage.
Utility model content
In view of the shortcomings of the prior art, the technical problem to be solved by the utility model is to provide one kind can effectively preventing oil gas
The engine aspirating system of leakage, to achieve the purpose that prevent the oil gas of inlet manifold from channeling on canister control valve.
In order to solve the above-mentioned technical problem, technical solution used by the utility model is：
This can effectively prevent the engine aspirating system of oil and gas leakage, including inlet manifold and canister control valve, it is described into
It is connected by pipeline between gas manifold and canister control valve, on the pipeline being connected between the inlet manifold and canister control valve
Equipped with check valve, the conducting direction of check valve is canister control valve to inlet manifold.
Further, the check valve is electromagnetism check valve.
The pipeline being connected between the inlet manifold and canister control valve is hose.
The check valve is located at connected pipeline middle position.
The hose includes connection rubber tube I and connection rubber tube II, and I one end of connection rubber tube is connected with inlet manifold, connects glue
I other end of pipe is connected with check valve one end, and II one end of connection rubber tube is connected with canister control valve, II other end of connection rubber tube and list
It is connected to the valve other end.
Two connecting pins of the check valve are stretching connector, stretch out connector and are equipped with one group of outer connected in star.
The utility model compared with prior art, has the following advantages：
The engine aspirating system is reasonable in design, pacifies on the connection rubber tube between inlet manifold and canister control valve
Check valve is filled, prevents the oil gas of inlet manifold from channeling on canister control valve, unidirectional prevention oil gas is played and enters, avoid leakage wind
Danger；And it is simple in structure, it is of low cost.
Description of the drawings
The content expressed by each width attached drawing of this specification and the label in figure are briefly described below：
Fig. 1 is the utility model inlet manifold and canister control valve connection diagram.
Fig. 2 is the utility model check valve oil gas direction schematic diagram.
Fig. 3 is existing inlet manifold and canister control valve connection diagram.
In figure：
1. inlet manifold, 2. connection rubber tubes I, 3. check valves, 4. connection rubber tubes II, 5. canister control valves.
Specific implementation mode
Below against attached drawing, by the description of the embodiment, making to specific embodiment of the present utility model further detailed
Thin explanation.
As depicted in figs. 1 and 2, this can effectively prevent the engine aspirating system of oil and gas leakage, including inlet manifold 1 and carbon
Tank control valve 5 is connected between inlet manifold 1 and canister control valve 5 by pipeline.Oil gas is adsorbed using canister, when automobile exists
, may be big due to the pressure of inlet manifold after anxious deceleration and parking, the oil gas of inlet manifold is channeled on canister control valve, is also had
Certain risk of leakage.
The pipeline being connected between inlet manifold 1 and canister control valve 5 is equipped with check valve 3, and the conducting direction of check valve 3 is
Canister control valve is to inlet manifold.It prevents the oil gas of inlet manifold from channeling on canister control valve, plays unidirectional prevention oil gas and enter,
Avoid disclosure risk.
Check valve 3, which is electromagnetism check valve, can open convenient for control in normally travel.Inlet manifold and canister control
The pipeline being connected between valve is hose, convenient for connection.Check valve is located at connected pipeline middle position, and connection and reasonable arrangement is convenient for
Installation.
Hose includes connection rubber tube I 2 and connection rubber tube II 4, and I 2 one end of connection rubber tube is connected with inlet manifold, connection rubber tube
I other end is connected with check valve one end, and II 4 one end of connection rubber tube is connected with canister control valve, II other end of connection rubber tube and list
It is connected to the valve other end.
Two connecting pins of check valve 3 are stretching connector, stretch out connector be equipped with one group of outer connected in star, connection rubber tube with stretch
It is easy to go out connector connection, and sealed reliable, is less prone to leakage problem.
The utility model is exemplarily described above in conjunction with attached drawing, it is clear that the utility model specific implementation not by
The limitation of aforesaid way, as long as using the improvement of the various unsubstantialities of the design and technical solution progress of the utility model,
Or it is not improved the design of the utility model and technical solution are directly applied into other occasions, in the guarantor of the utility model
Within the scope of shield.
