Description
Affiliated technical field
The utility model relates to a kind of gasoline-saving device that is used for motor, is specifically related to a kind of fuel energy-saving emission reduction controller of engine.
Background technique
According to principle of dynamics, the motion speed of vehicle is fast more, and inertia is big more, and the torsion that vehicle needs is more little, and the fuel of consumption is corresponding few more.Vehicle is at a high speed or when driving at moderate speed, engine power increases and should reduce with inertia, fuel delivery also should reduce thereupon, the design of vehicle is by acrotorque at present, maximum climbing, the maximum loading design, its fuel delivery can not be with the speed of a motor vehicle, useful load, the variation of running environment and changing, can not under dynamic condition, adjust fuel delivery, when the speed of a motor vehicle improves the inertia increase, its fuel system is still with a kind of pattern, when not needing fuel feeding, the mountain area descending still do not continuing fuel feeding, therefore the present situation of vehicle operating is: the fast more excessive fuel consumption more of the speed of operation, this is contrary with the inertia working principle, can not accomplish rationally to adjust at random fuel delivery, make motor when work done, produce a large amount of harmful gases simultaneously.Waste fuel oil on the one hand, increased toxic emission on the other hand, caused environmental pollution.
Summary of the invention
Providing a kind of can manually or automatically and reasonably adjust fuel delivery at random according to working conditions of different engines and change the purpose that reaches reasonable fuel feeding, the fuel energy-saving emission reduction controller of engine that reduces toxic emission thereby goal of the invention of the present utility model is to overcome the above-mentioned deficiency of prior art.
The technical solution of the utility model is: comprise oil inlet pipe, jet, the spool of can regulate oil pump capacity is arranged in the controller, the working connection import of spool is connected with oil inlet pipe, and the working connection outlet of spool is corresponding with jet; Overflow mechanism is arranged in the controller.
The jet of described controller is one or more, and corresponding with it respectively working connection outlet is arranged on the spool, and the import of spool working connection is connected with oil inlet pipe respectively, and each working connection outlet of spool is corresponding with its jet respectively.
When described jet is one, be used for single-cylinder engine, jet is used for multicylinder engine when being a plurality of.
Its working connection outlet end of the spool of described can regulate oil pump capacity has involute circular arc oil groove, the flow channel aperture of its involute circular arc oil groove and spool working connection corresponding part maximum, diminishes to flow channel and closes gradually.
Described overflow mechanism inner chamber is connected with oil inlet pipe and oil spill pipe respectively, and overflow mechanism comprises and can change the one-way valve of opening or cutting out with system oil pressure: one-way valve is loaded on overflow mechanism and oil inlet pipe connecting port, and one-way valve one end has regulator.
Described regulator is a pressure adjusting spring, and pressure adjusting spring one end is complementary through latch bracket and one-way valve, and the other end is equipped with the adjustment screw.
The utility model is loaded between the high pressure oil pump and oil nozzle of vehicle motor, need not change the basic structure of vehicle.
The utility model is applicable to various vehicles, and boats and ships, generator set, internal combustion locomotive are specially adapted to diesel vehicle, also is applicable to EFI gasoline vehicle simultaneously.According to the speed of a motor vehicle, can manually order about or order about automatically the spool rotation, the utility model is transferred to required fuel delivery, when the speed of a motor vehicle surpasses 120km/h, spool rotates to minimum fuel feeding state, make engine chamber reach lean combustion, make oil inflame complete, reach the purpose of energy saving, control discharging; When the speed of a motor vehicle reduces, can manually order about or order about automatically the spool rotation to the fuel delivery adjustment, when the speed of a motor vehicle is lower than 40km/h, spool can be rotated to maximum, return to original design fuel feeding state.When the descending of mountain area, spool rotates to closed condition, and fuel delivery is almost nil, makes not oil firing of automobile downhill engage a gear, guarantees each parts proper functioning, meets the regulation of traffic law again.
The utility model compared with prior art has following advantage and good effect: do not change the basic structure of vehicle, implement easily; Can rationally adjust the variation of trace control fuel delivery at random according to working conditions of different engines, thereby reach the purpose of reasonable fuel feeding, reduce toxic emission; Promptly realize high speed fuel-economizing, lean combustion, reached the purpose of energy-saving and emission-reduction substantially.The stand test of carrying out through the detection data and the research institute of Dong Feng Auto Corporation of automobile carrier using energy source inspection center of Ministry of Communications shows: fuel saving ratio is more than 6%; Smoke intensity conversion ratio 94-98%.
