Wherein, also be provided with discharging valve bottom the described gas holder.
The present invention has following advantage compared with prior art: 1, simple in structure, easy to operate; 2, overcome the difficult problem that pure hydrogen vehicle is difficult to start winter; 3, overcome intake duct and advanced the uncontrollable difficult problem of amounts of hydrogen; 3, air inlet and pressure control adopt microcomputerized control, automation, intelligent degree height; 4, light-emitting diode display shows, working procedure is all shown on it, and the people is come into plain view; 5, intelligent cold start-up adjuster adopts soft switch control technique, controls more stable, more accurate.
Four, description of drawings
Accompanying drawing is the structural representation of an embodiment of the present invention.
Five, embodiment
With reference to accompanying drawing, a kind of cold start device of alcohol-hydrogen mixed fuel engine, comprise sky filter 9, mixer 19, heat radiation volute 12, pyrolysis apparatus 13, ignition switch 14, storage battery 15, outlet pipe 18 and motor 20, empty filter 9 is installed in mixer 19 tops, the bottom of mixer 19 is connected with the suction tude of motor 20, on the outlet pipe 18 of motor 20 pyrolysis apparatus 13 is installed.Pyrolysis apparatus 13 tops pipeline in turn connect heat radiation volute 12, gas holder 2, air filter cup 3, first threeway, 4 two ends and second threeway, 6 two ends, and be connected with mixer 19 sides one end pipeline by gas storage solenoid valve 8, the other end of first threeway 4 is connected with pressure transducer 5 pipelines, and the other end of second threeway 6 is connected with mixer 19 side the other end pipelines by cold start-up solenoid valve 7; The positive pole of storage battery 15 by ignition switch 14 respectively with an end of gas storage switch 10, one end of cold starting switch 16 and second end of pressure controller 11 are connected, the negative pole of storage battery 14 respectively with the 3rd end of pressure controller 11, first end of cold start-up adjuster 17 and an end cable of gas storage solenoid valve 8 connect, the other end one tunnel of gas storage switch 10 is connected with first end cable of pressure controller 11, another road is connected with the other end cable of gas storage solenoid valve 8, the other end of cold starting switch 16 is connected with second end cable of cold start-up adjuster 17, the 3rd end of cold start-up adjuster 17 is connected with two end cables of cold start-up solenoid valve 7 with the 4th end, and the 4th end of pressure controller 11 is connected with two end cables of pressure transducer 5 with five terminal.Gas holder 2 bottoms also are provided with discharging valve 1.
During operation, behind vehicle driving one segment distance, just having hydrogen in the pyrolysis apparatus 13 produces, when the colder needs of weather stop, shift to an earlier date 2～5 minutes gas storage switch 10 cuts out, at this moment the hydrogen that produces in the pyrolysis apparatus 13 just can be stored in the gas holder 2, and pressure controller 11 this moment (XMT602 is intelligent in employing) just can detect by the pressure in 5 pairs of gas holder of pressure transducer 2.It is 4 kilograms of pressure that pressure controller 11 is provided with upper limit parameter, and the lower limit parameter is 3 kilograms of pressure.When the pressure in the gas holder 2 reaches 4 kilograms of pressure of the upper limit, pressure controller 11 just can be sent unnecessary hydrogen into motor 20 by gas storage solenoid valve 8 and burn, when the pressure in the gas holder 2 is discharged into 3 kilograms of pressure of lower limit, just gas storage solenoid valve 8 cuts out, so circulation remains pressure in the gas holder 2 between 3～4 kilograms, the hydrogen supply when guaranteeing cold start-up.
When the needs cold start-up, cold starting switch 16 is opened, cold start-up adjuster 17 just can be sent hydrogen into motor 20 with hydrogen by mixer 19 by cold start-up solenoid valve 7, burn jointly with fuel-air mixture, because the burning-point of hydrogen is very low, so be easy to just fuel-air mixture be lighted, finish the process of cold start-up.Cold start-up after finishing is closed cold starting switch 16, and gas storage switch 10 is opened, and motor enters normal working.
