The utility model relates to a decompressing and air-evaporating device for a gasoline motor vehicle, which comprises a shell, a liquid inlet port, a gas outlet nozzle, a safety valve, etc. The utility model is characterized in that an evaporation chamber is arranged in the shell, and a preheating water passage is arranged on the periphery of the evaporation chamber; an adjustable valve is assembled in the position of a gas outlet hole of the evaporation chamber, and the adjustable valve is provided with a valve hole and a valve core matched with the valve hole; one side of the valve core is provided with a spring, the other side of the valve core is fixedly connected with a diaphragm by a valve rod, and a regulating spring and a regulating handle is assembled on one side of the diaphragm. The utility model has the advantages of fuel saving, high sensitivity of gas supply, good acceleration performance, no possibility of the reduction of engine power, structural simplification, convenient operation and maintenance, and low manufacture cost, and is suitable for being used for various large-size, medium-size and small-size gasoline engine vehicles.
Description
The utility model belongs to a kind of gasoline fueled motor vehicle parts, particularly a kind of reduction vaporization device of air that is applicable to gasoline fueled motor vehicle with LP gas fuel.
In order to reduce the pollution of Motor Vehicle burns gasoline discharging tail gas to atmosphere environment, world many countries all promoting automotive fuel employing liquefied petroleum gas (LPG) technology, changes " gas " by " oil ", and liquefied petroleum gas (LPG) reduction vaporization device of air must be installed in motor car engine.At present, the liquefied petroleum gas (LPG) reduction vaporization gas equipment domestic and import that China uses is installed on the petrol engine, can be on the basis that does not change primary car structure, realization uses the function of liquefied petroleum gas (LPG), two kinds of fuel of gasoline, automobile uses liquefied petroleum gas (LPG), but fuel saving takes 30-40%, and the COHC in the exhaust emissions all descends more than 90%, reaches national specified discharge standard.Economic benefit, social benefit, environmental benefit all are very significant.But also have the following disadvantages:
1, when using liquefied petroleum gas (LPG), must earlier start driving with gasoline, treat that engine water temperature reaches more than 40 ℃ just can use.
2, use earlier gasoline,, in this transfer process, have a certain amount of gasoline in the engine and carburetor float chamber and in the oil pipe, supply with simultaneously, form and repeat, cause waste with liquefied petroleum gas (LPG) after liquefied petroleum gas (LPG) is used in conversion again.
3, existing liquefied petroleum gas (LPG) equipment is confined to dilly, and reduces engine power, and device sensitivity is low, and accelerated reaction is slow, not anxious the acceleration.Structure is loaded down with trivial details, working service inconvenience, cost cost height.
The purpose of this utility model provides a kind of Motor Vehicle reduction vaporization device of air, and without the preheating of gasoline elder generation, cost saving is remarkable, and acceleration performance is good, designs simplification, and the cost cost is low, and working service is convenient.
The purpose of this utility model is achieved in that it comprises housing, liquid entering hole, outlet nozzle, safety valve etc., and it is characterized in that: vaporization chamber is set in housing, and the periphery of vaporization chamber is provided with the preheating water channel; Vaporization chamber air outlet hole place assembling adjustable valve, the spool that adjustable valve has valve opening and cooperates with it, spool one side is provided with spring, and opposite side is by the affixed diaphragm of valve rod; Spring and regulating handle are adjusted in side assembling at diaphragm.
Assembling slagging-off bolt on the above-mentioned vaporization chamber.
The utility model has the advantages that:
1, can possess the function of independent burns gasoline and two kinds of fuel of liquefied petroleum gas (LPG) simultaneously directly with liquefied petroleum gas (LPG) starting and driving; And can be in subzero across-the-line starting driving under the cryogenic conditions more than 25 ℃.
2, the fuel saving expense is remarkable, and air feed is highly sensitive, and acceleration performance is good, can not reduce the power of motor.Be applicable to large, medium and small various petrol engine vehicle.
3, designs simplification, working service is convenient, low cost of manufacture.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the utility model structural representation.
See Fig. 1, the utility model concrete structure is as follows: vaporization chamber 18 is set in the housing 19, and vaporization chamber 18 is provided with the liquid entering hole 13 of liquefied petroleum gas (LPG), assembling safety valve 22 (adopting the pressure relief valve of market sale) on the liquid entering hole 13; The periphery of vaporization chamber 18 is provided with annular preheating water channel 11.Annular preheating water channel 11 is provided with water intake 12 and water outlet 20.Central position at vaporization chamber 18 is provided with pressure regulating valve, has vaporization chamber air outlet hole 17 on the outer wall of pressure regulating valve, and pressure regulating valve is provided with valve opening 9, the spool 14 of assembling band valve rod on the valve opening 9, assembling spring 15 in valve; The bottom of valve is screwed slagging-off bolt 16.In the arranged outside underpressure chamber 21 of valve valve opening, underpressure chamber 21 is communicated with outlet nozzle 1.The top of underpressure chamber 21 connects firmly flexible sheet 2 by gland 6 and screw; The end of piston rod 10 connects firmly flexible sheet 2 by metal intermediate plate 3 and nut.Debug whole spring 5 in metal intermediate plate 3 upper group, spinning is adjusted handle 7 on the gland 6.At the outside of gland 6 assembling protecting cover 8.
Working principle: during installation with liquid entering hole 13 external liquefied petroleum gas tank of the present utility model, water intake 12 and water outlet 20 external automobile cooling water recirculation systems, outlet nozzle 1 connects the motor car engine firing unit, during work, liquid liquefied petroleum gas (LPG) enters in the vaporization chamber 18, because the water temperature of cooling water is when also passing through preheating water channel 11 more than 40, liquefied petroleum gas (LPG) is heated, the liquefied petroleum gas carburation by evaporation also improves air pressure, liquefied petroleum gas (LPG) enters pressure regulating valve by steam chamber air outlet hole 17, pass through valve opening 9 then through underpressure chamber 21, enter the engine combustion device from outlet nozzle 1 at last.When needs are adjusted the valve opening flow of valve, rotate and adjust handle 7, by spring 5, diaphragm 2 makes spool 14 displacement up or down, thereby adjusts the circulation gap between spool 14 and the valve opening 9.Diaphragm 2 plays the effect of suitable conciliation gaseous-pressure, and diaphragm raises up when pressure is a little greatly, and diaphragm was recessed down when pressure was littler.On gland 6, have air ventilation aperture 4, the inside and outside differential pressure that produces owing to the diaphragm knee-action with balance.Slagging-off bolt 16 is mainly used in regularly to back out removes the inner fuel sediment, simultaneously reinforcement effect is played in the bottom of vaporization chamber 18, causes damage to prevent that vaporization chamber air pressure is excessive.
