Working principle of the present utility model:

Automobile liquid gas transducer is that post-decompression liquid fuel is sent into inlet union 1, enters low pressure chamber a by filter screen 2, check valve 3, pressure regulation cap 6, evaporates expansion rapidly through preliminarily heated liquid fuel.Heating is to be finished at heating chamber b by the heat recirculated water of two water outlet connectors 10 turnover, and being finished by electric heating tube 34 in the employing heating chamber when north of china in winter start treats that engine operation just often can cut off this power supply.Liquid fuel enters hyperbaric chamber c through valve 7 and channel seat 9 and heats once more, forms liquid gas mixing shape, makes increased pressure.If this moment, motor was under idle state, the high pressure diaphragm 13 pulling valve rod assemblies 12 in the c of hyperbaric chamber drive valve 7 and move, and closing passage seat 9 stops the air inlet of low pressure chamber a, has controlled the force value of hyperbaric chamber c.When engine start, make vacuum chamber d produce negative pressure by vacuum tube 35, vacuum diaphragm 20 drives top assembly 21 displacements, and negative pressure diaphragm 25 pusher arm plate 24 under negative pressure is opened valve block 26, make hyperbaric chamber c gas enter the e of negative pressure chamber, enter motor through exporting 27 again through bend pipe 31.During engine idling condition, fuel is to enter solenoid valve seat 37 by the gas in the c of hyperbaric chamber through idling bend pipe 14, idling flexible pipe 40, idling adjustment seat 38, needle-valve 39, enters the e of negative pressure chamber, enters motor through outlet connection 27.When motor broke down tempering, the negative pressure diaphragm 25 in the e of negative pressure chamber was thrown off arm plate 24 rapidly under the effect of back pressure, close valve block 26 under spring assembly T6 effect.The hyperbaric chamber c pressure of closing increases drive high pressure diaphragm 13 and valve rod assembly 12 makes valve 7 closing passage seats 9, the fuel that the cutoff low chamber is come, be stopped in the rapid supercharging of low pressure chamber liquid check valve 3 is closed, thorough fuel shutoff source, thus play backfireproof, explosion-proof effect.

The utility model has following advantage compared with prior art: this installs, and it is simple in structure, multiple functional; Draw materials easily, replace a large amount of non-ferrous metals; Manufacturability is good, easily forms large-scale production; Add and use the standard equipment manufacturing man-hour, need not to increase special device; Easily assembling is easy to maintenance; Cost is low, and comparing with the import like product is 1/5, has reduced whole entrucking cost, is easily accepted by manufacturer and user.Easy for installation, can change arbitrarily to adjust and import and export the position that adapts according to the mounting point of different automobile types; Electric heating appliance is arranged, easily starting winter; Being provided with heating chamber b between hyperbaric chamber c, the low pressure chamber a, is to use heat recirculated water in the heating chamber b, has explosion-proof, anti-backfire Safety function.This device is that the formation inflammable mixture entered motor and fully burning after liquid transition was become gas and air mixing simultaneously, and a large amount of harmful matters in the engine exhaust emission are obviously descended, and has controlled the pollution to atmosphere, fuel saving.What this device formed is the dry type gas with temperature, supplies engine combustion with air mixing, has improved the burning situation in vapour lacks, and reduces the destruction to lubricant oil, thereby has prolonged the working life of motor, reduces maintenance expenses.
