The utility model comprises following technological scheme, comprise the fuel economizer body, control circuit, the normal off electromagnetic gas valve, high pressure gas holder, described fuel economizer body comprises piston sleeve, piston, seal ring, piston rod, return spring, piston cap, described piston sleeve bottom is provided with pore, the pore outlet is provided with gas-tpe fitting, described piston and piston sleeve are complementary, be provided with the seal ring that matches between described piston and the piston sleeve, described piston tail end is connected with piston rod, be inserted in the guide hole of piston cap the outer end of described piston rod, be connected by return spring is movable between described piston and the piston cap, described piston rod outer end links to each other with connecting sheet with the push rod of the blanket of motor oil transfer pump; Described control circuit comprises power supply E, first K switch 1, second switch K2, described second switch K2 is located on the gas pedal, described second switch K2 is a normally closed switch, two power-line terminals of described normal off electromagnetic gas valve join with second switch K2 and ground wire respectively, second switch K2 disconnecting circuit when stepping on the gas, and electromagnetic coil quits work, the normal off electromagnetic gas valve is promptly closed gas circuit, otherwise unclamp throttle, second switch K2 promptly connects circuit, and the normal off electromagnetic gas valve is connected gas circuit; Described high pressure gas holder is provided with a tracheae, is serially connected with above-mentioned normal off electromagnetic gas valve on the described tracheae, and the far-end of described tracheae links to each other with above-mentioned gas-tpe fitting.
The utility model programmed sequence of operations and working principle are as follows: under the cruising state, and the conventional fuel feeding of motor.When needs adopt this fuel-economizing device, at first (first K switch 1 can be located on the bridge operation panel with first K switch 1, also can be located at the position of other easy-to-operat) closure, make control circuit enter working state, when automobile at descending, slow down or when utilizing inertia traveling, the gas pedal of unclamping not out of supply, second switch K2 promptly connects circuit, gas circuit is connected in the action of normal off electromagnetic gas valve, pressurized air feeds in the piston cavity of fuel economizer body immediately, piston is compressed air push, piston drives piston rod and overcomes the return spring resistance and stretch out guide hole on the piston cap, piston rod promotes the push rod of the blanket of motor oil transfer pump again by connecting sheet, thereby oil circuit is closed; When the needs cruising, the said procedure reverse operating, accelerator pedal, second switch K2 is a disconnecting circuit, gas circuit is closed in the action of normal off electromagnetic gas valve, and piston is return under the effect of return spring, again by the push rod pulling return of piston rod with the blanket of motor oil transfer pump, thereby the connection oil circuit recovers fuel feeding.
Employing the utlity model has following advantage:
1, the utility model oil-saving effect is remarkable, and test shows that the heavy truck fuel saving ratio is 20-25%, and the Light-duty Vehicle fuel saving ratio is 15-20%.
2, its Installation and Debugging are convenient, safeguard also simpler.
3, it is simple in structure, low cost of manufacture, and gain quick return in customer investment.About about 300 yuan of its retail price, the user uses about one month and can recoup the investment.
4, adopt this product, the motor running temperature can reduce, and oil inflame is effective, has reduced the black smoke phenomenon, has reduced environmental pollution.
5, the employing of this product is automatically controlled in conjunction with pneumatic principle, and it is easy to use, and performance is safe and reliable.Its idling fuel feeding can be completely severed when not needing fuel feeding, but connects oil circuit and recover fuel feeding when need moments in when oil, has both reached the purpose of fuel-economizing, does not influence the direction power-assisted again and the vacuum brake power assisting device normally uses.
