Usually gasoline car can improve power by suction tude or oil circuit supercharging, performances such as energy-conservation and environmental protection.But petrol engine is limited by detonation, and its supercharging amplitude is very limited, so can not satisfy the boost demand of other liquid such as Aalcohols fuel.The utility model is a combination property of improving the pluralities of fuel automobile by the supercharging amplitude of widening fuel system.
Summary of the invention
The purpose of this utility model is: provide a kind of easy to install and use, safety and environmental protection, range of regulation wide, adapted to the pressure governor of multiple liquid fuel.Increase the injection pressure of oil sprayer by the supercharging amplitude of widening fuel system, make it to be applicable to multiple liquid-fueled vehicle and obtain the better synthesis benefit.
Technical solution of the present utility model is: a kind of liquid fuel pressure governor is made up of pressure governor shell, hydraulic pressure relief piston; The pressure governor shell is made up of vacuum cylinder valve shell and oil pressure valve body case, the hydraulic pressure relief piston is positioned at the pressure governor shell, the vacuum cylinder valve shell is by pressure regulation spring top flat, pressure regulation spring, be connected with the hydraulic pressure relief piston, the oil pressure valve body case by vaccum seal ring, oil pressure seal ring, oil-feed filter oil sealing, the scavenger valve seal ring is connected with the hydraulic pressure relief piston.
Its top of the described vacuum cylinder valve shell of above-mentioned a kind of liquid fuel pressure governor is provided with regulates bolt and vacuum tube;
The described oil pressure valve body case of above-mentioned a kind of liquid fuel pressure governor, its underpart is provided with oil inlet pipe, oil outlet tube and return tube.
The described hydraulic pressure relief piston of above-mentioned a kind of liquid fuel pressure governor, its inside are provided with pressure regulation spring top flat, pressure regulation spring, hydraulic pressure relief piston, vaccum seal ring, oil pressure seal ring, oil-feed filtration oil sealing, scavenger valve seal ring.
Its working principle is: increase the top power of pressure regulation spring to relief piston by regulating bolt, reach the effect that promotes oil pressure and increased oil mass; The fuel pressure that enters oil sprayer is regulated in variation according to air inlet vacuum valve pipeline vacuum degree, and fuel pressure and suction press are remained unchanged, to guarantee that injection pressure keeps constant under motor different load and rotating speed.Regular price gasoline is 225kpa, and Aalcohols fuel is worth far above this; By the degree of vacuum Regulation spring dynamics of vacuum tube, open and close oil return switch valve control recirculating oil quantity; Vacuum seal encloses the effect of sealing degree of vacuum; The oil pressure seal ring keep-ups pressure the fuel sealing; It is diaphragm that the fine setting piston is arranged in the hydraulic pressure relief piston, and diaphragm is regulated oil pressure, oil mass by top spring and degree of vacuum; Oil sealing, filtering fuel impurity are filtered in oil-feed; The scavenger valve seal ring can not be revealed fuel.
Organic effect of the present utility model is: by promoting oil circuit pressure, can increase the compression ratio of motor, start motor-drivenly can reach 15～25% thereby promote, discharging can reach the above standard of European III, and energy-saving effect reaches 20～33%.
