Detailed description of the invention
The technical characterstic of the present invention is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The present invention is a kind of self-cleaning automobile OCV valve, including valve shell, is provided with front end valve cavity in valve shell
With rear end valve cavity, it is provided with guiding valve in the valve cavity of front end, is provided with coil in the valve cavity of rear end, is socketed with in coil
Plunger；Described guiding valve slides setting in the valve cavity of front end, and the front end of guiding valve is provided with spring, and one end of spring connects guiding valve
Front end, the other end of spring connects front end valve cavity inwall；Described coil connects electronic control unit；Before valve shell
End is provided with some fuel feed holes, and fuel feed hole connects lubricating oil pump.It is provided with thread groove, thread groove on the valve cavity inwall of described front end
Arranging in cylindrical screw-type, the pitch of thread groove is the 1/8 of the length of front end valve cavity, and the helical angle of thread groove is 24.7
Degree.
The setting of thread groove improves the lubricity of front end valve cavity.When guiding valve slides in the valve cavity of front end,
Engine oil flow in the valve cavity of front end is poor, have impact on cleaning performance, in the setting of thread groove makes front end valve cavity
Machine oil in guiding valve sliding process can threadingly groove guide direction flowing, add the lubricity of front end valve cavity.
Simulate through digital modeling, draw according to the fluidity testing data of machine oil, the pitch of thread groove is set to front end valve body empty
The 1/8 of the length in chamber, when the helical angle of thread groove is set to 24.7 degree, flow effect is preferable.
The using method of a kind of self-cleaning automobile OCV valve, is made up of following steps: started by electronic control unit identification
Machine operating condition, electromotor, in operation process, does not perform OCV valve self-cleaning program, when electromotor is in non-operating state, holds
Row OCV valve self-cleaning program；When electromotor is in non-operating state, electronic control unit sends n electric pulse letter to OCV valve
Number；When an electric impulse signal received by OCV valve, the coil generating electromagnetic power of OCV valve, attract plunger band movable pulley to move to the left,
Back-moving spring is compressed；Electric impulse signal disappears, and coil electromagnetism power disappears, and back-moving spring is by guiding valve fight back home position, guiding valve
Complete once to move back and forth；OCV valve is received next electric impulse signal and is moved back and forth the most as above；Work as pulse
Counter values is more than or equal to n, or engine start machine rotating speed is more than or equal to setting speed, terminates this program.
Described setting speed is 40 revs/min.
Described electronic control unit, when OCV valve sends electric impulse signal, sends electric impulse signal to oil pump, and oil pump is connecing
During to electric impulse signal, to OCV valve pump oil.
Described non-operating state includes the non-fired state of electromotor and engine misses state.
It is an advantage of the current invention that it can overcome the drawback of prior art, reasonable in design is novel.By adding from clear
Washing function, can effectively prevent sliding valve movement to be obstructed or clamping stagnation problem occurs, this scheme does not increase cost, but eliminates fault,
There is broader application market.
Certainly, described above is not limitation of the present invention, and the present invention is also not limited to the example above, the art
Those of ordinary skill, in the essential scope of the present invention, the change made, retrofit, add or replace, all should belong to the present invention
