For the fuel oil supply system of the prior art when using kerosene burning to run engine, engine is in idling point
Difficulty in starting when fiery.The idling fuel oil device for supplying 2 of the utility model realizes the startup of engine by burns gasoline, works as hair
After motivation starts, the gasoline that idling fuel oil device for supplying 2 provides is closed, maintains to send out using the kerosene in fuel supply device 1
The normal operation of motivation.During work, gasoline is entered the idling float chamber of idling fuel oil device for supplying 2 by petrol pump or top petrol tank
23, when liquid level rises to certain altitude, float pin 26 just will be closed into the oil duct of needle seating 25.Stop gasoline entering.Work as liquid level
When fuel consumption declines, the oil duct of needle seating 25 is just opened because declining float pin 26, until the gasoline combustion that the unit interval enters
When material is suitable with engine consumption, float liquid level is just stablized in another new height again, because petrol engine is starting
When, engine speed is relatively low at this time, negative pressure it is small, it is necessary to available fuel reach that certain limit of inflame ability and self-ignition point etc. be adapted to can
Mixed steam is fired, the startup of engine is just can guarantee that and maintains stable idling speed, so idling fuel oil device for supplying 2 ensures
The Fuel Petroleum of gasoline engine characteristic necessarily is provided to start and maintain engine idling operation.Meanwhile engine is in low temperature
During situation, because of the normal idling combustion mixture of engine, rotating speed is too low on the engine, the reasons such as compression process is not adiabatic, with
And outside air temperature influences and combustion mixture that enleanment engine idling runs well, so fuel oil starting switch 4 can be passed through
A part of additional fuel is supplemented to ensure the cold start-up of engine.When engine throttle gradually opens big extremely a certain aperture, because of hair
The change of motivation vacuum, the offer gasoline combustion mixture fuel of idling fuel oil device for supplying 2, which is just reduced to rapidly, to be stopped,
And then the high speed circuit of fuel supply device 1 is started to work, main jet pipe starts kerosene gaseous mixture, passes through main jet and air jet
Cooperatively form flammable kerosene gaseous mixture, ensure engine load run well.
For the fuel oil supply system of the prior art when using kerosene to run, engine start is difficult, and bar transfer is steady
Determine poor performance.The fuel oil supply system of the utility model, maintains to send out after starting engine by burns gasoline using kerosene
The high speed operation of motivation, not only reduces directly using the high expense of gasoline operation engine, and solve direct combustion
Burn the problem of kerosene is difficult to start engine.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art work as can make various corresponding changes and deformation according to the utility model, but these
It is corresponding to change and deform the scope of the claims that all belong to appended by the utility model.
