What the utility model adopted aspect fuel feeding is oil pump is directly given sealing by main fuel supply line (48) fuel feeding oil storage tank (46), in sealing oil storage tank (46), is furnished with a check valve (67), oil pump is when being oil storage tank (46) fuel feeding, oil pressure is greater than 1 barometric pressure in its jar, its pressure size is a Variable quantity, and when engine running speed increased, oil pressure can increase thereupon in jar, otherwise then reduce, provide precondition for engine operation active fuel feeding like this.When motor is starting, quickens, during at the uniform velocity with variable-speed operation, can guarantee in the extremely short time to provide for motor the fuel delivery under the various operating conditionss, thereby just changed the slowness of the passive fuel feeding of traditional vaporizer.

With the supporting control electromagnetic valve in addition of oil storage tank, its effect mainly is the fuel feeding and the oil-break of control oil storage tank.The power line of this solenoid valve (56) joins with the closed outlet of ignition switch.When opening ignition switch, solenoid valve picks up sucker, opens thereby beat the oil storage tank oil outlet, for ato unit has been carried out the fuel feeding preparation.Close ignition switch after stopping, solenoid valve cuts out the oil storage tank oil outlet, has just guaranteed that storage at any time is full of 1 atmospheric fuel oil in the oil storage tank, for ato unit is next time got ready.

Fig. 2 has described the working principle and the assembling situation of other system of the utility model except that " solenoid valve oil storage tank system ".Below subsystem is described in detail:

(1), " main oil gallery fuel feeding and force atomization system ", this system is made up of delivery valve (43), main spindle valve body (38), main spindle (35), end cover (36), idling spindle valve body (34), idling spindle (31), idle fuel tube joint (39), sebific duct, delivery valve adjustment disk (1), oil nozzle (41), impingement plate (40) and knob etc.

At first allocate fuel feeding adjustment disk (1) into delivery valve (43) during assembling, fastening with a M3 * 6 screws, require not make valve point and exterior edge face impaired, it is fastening then the delivery valve main shaft to be joined two M4 * 6 screws, oil nozzle (41) is coated 502 mucilage bindings fit on the impingement plate (40), join spring pad impingement plate (40) is assemblied on the delivery valve main shaft, require assembling fastening, it is horizontal that impingement plate (40) matching requirements keep, and do not have obviously.Then, main spindle (35) is assemblied in the valve body (38), in end cover, join an oil resistant seal rubber pad, end cover (36) is assemblied on the main spindle valve body (38), again knob is fastened on the rear end of main spindle (35) with a M3 * 6 screws, main spindle valve body (38) and solenoid valve oil storage tank system is 90 ° joins oil resisting rubber jointing and be assemblied in and connect on the main body (37).Idling spindle (31) is assemblied on the idling spindle valve body (34), other assembling is identical with main spindle, then with idling spindle valve body (34) with connect main body (37) and join oil resistant seal rubber pad assembling, at last two oil connections (39) are joined the oil resistant seal rubber pad respectively and be assemblied on connection main body (37) and the idling spindle valve body (34), again oil resistant heatproof sebific duct is assemblied on the oil connection (39).

After more than assembling finishes, require absolute sealing and soundness.

The size that the main function of native system is carried out the active fuel feeding and regulated fuel delivery with motor.After solenoid valve is opened, pressurization fuel oil in the oil storage tank is promptly located along with oil duct is passed to oil nozzle (41) through main shaft pin (35), the amount of outwarding winding of main spindle (35) can be carried out the adjusting of optimal selection according to the working condition of motor, after fuel oil is flowed through main spindle (35), at this moment, as long as delivery valve (43) is not opened, vaporizer still is in not fuel feeding state.When needing ato unit, as long as step on the throttle pedal, closure link rod (3) the delivery valve adjustment disk (1) that will link is done inverse time direction rotation, thereby is opened oil duct.What delivery valve (43) adopted is M8 screw mandrel linking type opening/shutting valve, its maximum amount of outwarding winding (angle) is 0 °～100 °, and the valve opening and closing gap is 0～0.35mm, and the oil duct metering-orifice is φ 2mm, the valve wedge angle is 60 °, can guarantee the supply of the required fuel oil of motor full-speed operation fully.When gas pedal is stepped on, link rod (3) on the adjustment disk on the closure (9) drives delivery valve adjustment disk (1), does inverse time direction rotation, and delivery valve (43) is opened, the fuel oil of main oil gallery can promptly spray, and throttle (closure) is stepped on to such an extent that the fuel oil of big more long more supply of time is just many more.

It is the impingement plate of garden shape (40) that a horizontally disposed figure is arranged in the below of oil nozzle (41).When motor in the running, in vaporizer, can form the pressurization fuel oil that certain negative pressure and oil pump are imported oil supply system, spray with oil nozzle (41), the a spot of air that enters with the air jet (42) of its top tentatively mixes, ejection at a high speed, and beat on impingement plate (40), flow velocity is big more, the energy that collision produces is big more, and the particle of petrol molecule is just more little thus.Petrol molecule is beaten after impingement plate (40) is gone up, promptly being circumference disperses, again the petrol molecule particle after the collision is for the first time beaten on the internal chamber wall (8) at vaporizer, make petrol molecule particle after colliding once more littler, created good condition for entering cylinder acting burning, can fuel oil has been fully burned.

(2), " closure and delivery valve linked system ": this system mainly is made up of closure (12), axle (11), throttle adjustment dish (9), link rod bolt (2 and 7), link rod overcoat (5), adjusting link rod (3) and gas pedal stay-bolt (10) etc.

Forcing atomizing impingement plate (40) below to be fitted with the closure (12) of regulating air inflow.Throttle adjustment dish (9), link rod bolt (7) are arranged on throttle plate pin (11).Throttle adjustment dish (9) is connected with former car accessory gas pedal pull bar.Regulating link rod (3) is connected with link rod bolt (2) with delivery valve adjustment disk (1) and is synchronized with the movement.

On two adjustment disks (1,9) different φ 4.2 apertures to bore dia of three rows are being arranged up and down, each aperture is between left and right every about each 1mm.The adjustment hole that these are countless is mainly used in the value ratio between the fuel delivery of the air inflow of regulating closure and delivery valve.Such as, in different area in different seasons, different vehicle conditions and different carrying capacities are adjusted the ratio of inflammable mixture selectively.Aperture in the throttle adjustment dish (9) (51 among Fig. 3), more little to the aperture, mixture strength is more little, otherwise then big.On delivery valve adjustment disk (1), big more to hole (57 among Fig. 3) footpath, fuel delivery is more little, and mixture strength is just little, otherwise then big.When regulating link rod (3), assembling to guarantee that up-down adjustment dish (1,9) can reach 100 ° the amount of outwarding winding.

In " closure linked system " that Fig. 3 describes, what connect up-down adjustment dish (1,9) is can regulate link rod (3), when delivery valve is the contract fully shape, link rod (3) fixing bolt (2) is loaded on the amount of the outwarding winding position that can guarantee (43) 100 ° of delivery valves, how to select different adjustment holes, can select arbitrarily according to engine condition.After assembling delivery valve adjustment disk link rod, with closure (12) Close All, the fixing bolt (7) that will regulate link rod (3) again is assemblied in the best adjustment hole of throttle adjustment dish (9).After assembling finished, the air demand of idling operation was determined by the length of regulating link rod (3).

The concentration ratio that closure control can be regulated inflammable mixture selectively in engine operation.The opening angle of closure (12) is 0 °～100 °, and the air inflow maximum angular is about 60 °～75 ° of rotation, is the about 2/3 of gas pedal effective travel, and at this moment the mixed gas ratio be the best and most economical.When vehicle at shift speed change, under the lower situation of starting cold and temperature, motor needs denseer mixed gas, as long as at this moment continue the pedal of stepping on the throttle, the open angle of closure (12) will surpass the center line of vaporizer, and reduce the air inlet area, at this moment delivery valve is also opened increase constantly, form inverse ratio principle, be after throttle is trespassed about 2/3 stroke, air inflow can reduce thereupon, and the fuel delivery of delivery valve is on the increase, and then forms the state that proportions of ingredients concentration increases gradually, and engine speed steadily after, select best accelerator open degree by the driver again.This has also remedied traditional vaporizer and can only lean on simple accelerating pump and chock plate to regulate the mixture strength ratio, from operating more easy and having stronger randomness.

(3), " idle fuel way control system ": this system mainly is made up of negative control needle-valve (16) and negative air control valve (22).Wherein negative control needle-valve is made up of end cap, valve body (19), diaphragm (15), needle-valve (16), nut, spring, adjusting screw mandrel (17) and knob etc.; Negative air control valve is made up of valve body (29), end cap (24), air valve (22), negative pressure diaphragm (23,27), nut, sealed pressure pad, spring (26), adjusting screw mandrel (25), oil connection (28), negative pressure joint (20), negative pressure control conduit (18) etc.

The control principle of this system mainly is that the negative pressure that produces during with engine running is controlled.After solenoid valve is opened, be subjected to two negative control valves (16,22) control from the pressurization fuel oil of oil storage tank through regulating spindle (31), from control valve (16), fuel oil is drawn, an idling is arranged for nozzle (50) in closure (12) below, this idle fuel tube nozzle (50) is connected by idle fuel tube (30) with idle fuel tube joint (28), for engine idling operation provides fuel oil.Simultaneously, in closure (12) below a vacuum tube joint (52) is arranged in addition, this joint is identical with the vacuum tube joint of former vaporizer.

The idle speed control principle: the first, when vehicle when normal duty moves, closure (12) is opened, the main oil gallery fuel feeding.After closure is opened, the vacuum degree of closure (12) below can reduce, motor suction function negative pressure of (15,23,27) on two control valve diaphragms reduces thereupon, all less than the pressure of two diaphragm springs (pressure of diaphragm spring is for debugging), at this moment needle-valve (16) and air valve (22) are under the effect of spring, and needle-valve (16) is closed idle fuel way, and air valve (22) is out shape, whole idling oil circuit is the oil-break state, does not influence the proper functioning of motor.Second, when vehicle in gear shift operation, slow down and when sliding, at this moment closure (12) is closed, because the running speed height of motor, still keeping the high speed coasting at short notice, the vacuum degree of closure (12) below suddenly increases, air valve (22) is subjected to the negative pressure influence of powerful suction function on diaphragm (23,27), rapidly air valve (22) is closed, in-engine like this high negative pressure just no longer is transferred to the diaphragm (15) of needle-valve (16) and locates, needle-valve (16) is still closed, and idle fuel way is fuel feeding not, is the oil-break state.And traditional vaporizer is to want fuel feeding under such state, and this fuel feeding is the fuel feeding that do not do work, obviously, and owing to the structural unreasonable moving oil consumption of nothing that has caused motor.When recovering load operation again, whole system repeats the state of a control of first state again.The 3rd, when motor under idling operation running, at this moment closure (12) also is and closes, main oil gallery is fuel feeding no longer, when motor from high rotating speed under action of inertia, slow down gradually, when rotating speed was very low, in-engine negative pressure also reduced thereupon, to pressure less than the air valve diaphragm spring, air valve (22) is opened, and in-engine negative pressure is delivered to needle-valve diaphragm (15) and locates, and negative pressure at this moment is still out and away greater than the pressure of needle-valve diaphragm spring, and needle-valve (16) opened, whole idle fuel way is unimpeded, for the idling operation of motor provides required fuel oil, and then has guaranteed the running of normal idling operation.(annotate: the pressure of needle-valve diaphragm spring is less than the negative pressure of idling operation, and greater than the negative pressure of load running, the pressure of air valve diaphragm spring is only greater than approaching the negative pressure that the idling operation rotating speed is produced).

(4), " pressurization system ": topmost function of the utility model is exactly the pressure that increases in the engine cylinder, and the oxygen (air density) of abundance is provided for the adequacy of burning.Native system is the main body cover (8) of vaporizer, and the inner chamber of this shell has adopted bigbore project organization (greater than former vaporizer).Owing to adopted bigbore project organization, during the engine piston operation, enter cylinder with regard to having the fresh air of Duoing, and required fuel oil does not increase than traditional vaporizer, work as piston like this and move to the cylinder top dead center, will form the mixed gas compression ratio bigger than former compression ratio.Because the density of air has increased, the content of molecule and other composition that helps to burn have increased, in case igniting will make fuel oil be fully burned, improve the firing property of fuel oil effectively, and the power character of motor is significantly improved.In this case, motor does not influence power because of fuel mixture concentration reduces, and this mainly is to have adopted active fuel feeding in fuel feeding, and the influence that fuel feeding is changed by vacuum magnitude is very little.

Fig. 1, Fig. 2, Fig. 3 also are embodiments of the present utility model, and it is a kind of situation that the utility model is used for homemade truck " east wind " and " liberation " vehicle.In use, it is such installing and debug:

Earlier former vaporizer is taken off before installing, according to the installation direction of this vaporizer of choice of location of accelerator rod, to consider the effective travel of accelerator rod during installation, should remain on 20～30mm, the accelerator rod spring at a high speed at more loose state, but will be guaranteed maximum return degree.After vaporizer installs, at first main spindle (35) is closed the back and open 1/2 circle, idling spindle (31) is opened 1/8 circle, to bear air control valve (22) knob and all screw (dextrorotation), with the complete Hui Song (left-handed) of needle-valve knob (17), regulate link rod with closure (12) Close All after, link rod overcoat (5) screws 2 circles (dextrorotation or left-handed), and closure (12) is opened slightly.Several times earlier, partly fuel oil will be added in the oil storage tank before the ato unit with the hand arm pulling of oil pump.

Ato unit according to engine working conditions, is regulated main spindle selectively, is adjusted to best aperture, if occur the mixed gas overrich after the engine operation or cross when rare, adopts the pitch-row position of regulating on closure (12) and the delivery valve adjustment disk (1,9).If the mixed gas overrich is regulated the link rod bolt position to delivery valve adjustment disk (1) external diameter aperture, still overrich then can be regulated the link rod bolt on throttle adjustment dish (9) to the internal diameter aperture.If mixed gas is rare excessively, then the link rod bolt on the delivery valve adjustment disk (1) is regulated to the internal diameter aperture, throttle adjustment dish (9) is gone up the link rod bolt regulate to the external diameter aperture.Outside the adjusted method, regulate the effective travel of accelerator rod bolt, also can reach the ratio of regulating mixed gas.

After finishing with adjusted, regulate idling operation again.At first left-handed or dextrorotation 2 circles with the link rod overcoat make motor keep the overrich idling operation, progressively regulate link rod and idling spindle again, up to keeping best idling operation.

Optiumum control idling operation: at first with air valve knob Hui Song progressively, every time pine 1/2 circle, step on and loosen behind the throttle, after loosening up to stepping on the throttle, at this moment engine misses screw air valve knob 1/2 circle again, after loosening up to stepping on the throttle, motor is not flame-out to get final product, and uses the screw lock knob.Progressively screw the needle-valve knob at last, whenever revolve 1/2 circle, step on and loosen behind the throttle, up to idling flameout, at this moment, knob is returned pine 1/2 circle again, loosen after keeping stepping on the throttle, idling operation works well and gets final product, locking knob.Whole debugging work finishes.When treating vehicle starting, this vaporizer enters work.

The utility model has following advantage compared to existing technology:
