Description
Technical field
The utility model belongs to a kind of motor liquified gas Twin channel mixer and is mainly used in the use liquid gas, and LNG Liquefied natural gas etc. are the automobile of fuel, in the fuel yarn system of motorcycle and motor-helping car.
Background technique
Be the equal under steam discharge of noxious gases of Motor Vehicle of fuel with gasoline, diesel oil at present, cause environmental pollution, be detrimental to health.For this reason, pollute few with liquid gas, LNG Liquefied natural gas etc. are the automobile of fuel, motorcycle and motor-helping car development are comparatively rapid, compare with gasoline car, and it is not leaded that this kind fuel vehicle has tail gas, substantially sulfur compound not, carbon monoxide emission reduces more than 90%, and hydrocarbon can reduce 70%, advantages such as oxynitrides minimizing 40%.The Main Ingredients and Appearance of liquid gas is that the butane of about 60%～70% propane and about 30%～40% is formed, because two kinds material physical and chemical performance there are differences, both vapourizing temperatures are different with proportion, lean against and vaporize voluntarily in steel cylinder or the air cylinder that then propane proportion butane is light, its vapourizing temperature is low, causes its vaporization earlier, and this moment, vehicle power was good, speed is fast, but the engine charge shakiness.And when lpg consumption in steel cylinder or the air cylinder was approximately a greater part of, what residue was more in it be butane, because butane is than the difficult vaporization of propane, motor also is faced with the deficiency of air inlet shakiness at this moment.The engine charge shakiness causes fuel availability low, and the run stability deficiency need often to stablize for this reason and regulate combustion gas and the Air mixing amount that enters in the motor easily, and the conventional hybrid device can not satisfy this requirement.
Summary of the invention
The purpose of this utility model is a kind of motor liquified gas Twin channel mixer of design, makes it have often the stable combustion gas and the effect of Air mixing amount that enters in the motor of regulating easily, with the stability of raising fuel availability and engine running.For this reason, the utility model adopts the housing at mixer to be cross, advancing air scoop is the straight line duct with total air outlet, on the straight line duct, be provided with blocking-up, or open the needle type air throttle in this duct, the suction port that communicates with combustion gas communicates with the straight line duct by metering-orifice, needle type air throttle is by the valve body chamber vertical with the straight line duct and be positioned at the pull clamp of valve body indoor and the movable valve that can move and movable valve upper end within it, backguy, the adjusting shank of valve body Returnning spring and movable valve lower end constitutes, regulate shank and be arranged in metering-orifice, backguy one end is positioned at outside the housing, the backguy the other end is connected to the movable valve upper end, and the idling air outlet communicates with total air outlet, is provided with the air inlet adjustment valve rod of this air outlet open amount of control in the idling air outlet.The said structure design has realized the purpose of this utility model.The utility model has the advantages that and have often stable regulate the easily combustion gas that enters in the motor and the effect of Air mixing amount, to improve the stability of fuel availability and engine running, effect with the required gas quantity air feed of accurate each operating mode of control motor, improve fuel availability about 11%, and the stability of engine running is greatly improved, and also have simple in structure, easy operating, the advantage that user cost is low.

Embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model are by housing 1, and air conditioning road 5 and movable valve 16 are formed, and the housing of mixer is cross, advance air scoop 4 and are straight line duct 20 with total air outlet 9.On the straight line duct, be provided with blocking-up, or open the needle type air throttle in this duct.The suction port 18 that communicates with combustion gas communicates with the straight line duct by metering-orifice 19.Needle type air throttle is made of valve body chamber vertical with the straight line duct 21 and the adjusting shank 17 that is positioned at pull clamp 15, backguy 3, valve body Returnning spring 14 and the movable valve lower end of valve body indoor and the movable valve 16 that can move and movable valve upper end within it.End cap 2 roof pressure Returnning springs and upper end, closed valve chamber.Regulate shank and be arranged in metering-orifice, backguy one end is positioned at outside the housing and with the throttle lacing wire and is connected, and the backguy the other end is connected in the pull clamp of movable valve upper end, and pull clamp then is spirally connected with the movable valve upper end.Idling suction port 8 communicates with idling air outlet 13, and the idling air outlet communicates with total air outlet 9, is provided with the air inlet adjustment valve rod 11 of this air outlet open amount of control in the idling air outlet, is provided with seal ring 12 and spring 10 between this regulating valve stem and the housing.Described adjusting shank is a garden vertebra shape shank.
Described air conditioning road connects into air scoop and total air outlet, is provided with air conditioning valve rod 7 in it, is provided with retaining spring 6 between air conditioning valve rod and the housing, and its effect is to make air conditioning valve rod location.
During use, total air outlet 9 communicates with motor and the negative pressure of utilizing engine pump gas to produce will be positioned at straight line duct 20 combustion gas and air Mixture suction are used for motor, this moment, throttle was closed if motor is not loaded, movable valve sealing straight line duct, the adjusting shank 17 of its lower end all inserts the combustion gas of sealing in suction port enters the straight line duct in the metering-orifice, the idling air outlet 13 that a small amount of combustion gas then communicates with it along idling suction port 8 enter in total air outlet and with the air mixing that directly enters along air conditioning road 5 be motor confession mixed gas, the control of air and combustion gas inlet is with manually turning air inlet adjustment valve rod 11 respectively and air conditioning valve rod 7 is finished.If this moment is engine load or acceleration, then with hand turn throttle drive backguy 3 make lift on the movable valve 16 open the straight line duct and simultaneously on lift the adjusting shank that inserts in the metering-orifice and open suction port 18, to total air outlet simultaneously dosage inject combustion gas and air.Otherwise, unclamp throttle then movable valve lose the power of lifting and under valve body Returnning spring 14 effect, reset.
In a word, the utlity model has often stable regulate the easily combustion gas that enters in the motor and the effect of Air mixing amount, can promote the use of.
