Abstract
The utility model relates to an electric spraying throttle gate, belonging to electric throttle gate used in vehicle electric control fuel spraying system. The utility model comprises a main body, a throttle gate sheet, a helix rack, a torsion spring, a position sensor and a step motor which controls the opening degree of the by-pass channel of the main body. The main body is provided with an absorbing pipe which is communicated with an oil tank. The absorbing pipe is communicated with the gas inlet of the main body through an inner channel of the main body. the utility model has the advantages of automatically leading the volatilized fuel inside the oil tank into the engine for burning, eliminating the safety hidden dangers of oil gas burning and exploding of the oil tank, and effectively recycling and reusing the oil gas.
Description
Technical field
The utility model relates to the electronic air throttle body in the automobile electrically-controlled fuel injection system.
Background technique
The dynamo-electric controlled fuel injection of motor benzine system mainly comprises fuel tank, petrol pump, electric-controlled fuel injector, electronic air throttle body, central unit (ECU) etc.Wherein, the structure and the principle of electronic air throttle body are: its body interior has an air-flow path, one throttle blade that is installed on the throttle plate pin is arranged in the air flue, the rotation of throttle plate pin drives throttle blade and rotates in air flue, the aperture of corresponding change throttle blade, thereby the purpose of realization control air input of engine by air.A torsion spring is installed on the throttle plate pin, throttle plate pin is produced a reseting torque of closing gas-entered passageway.Position transducer is fixed on the throttle plate pin, to the rotational position of central unit (ECU) feedback throttle plate pin, promptly feeds back the opening information of throttle blade, realizes closed loop control.In addition, also be provided with idling air inlet by-pass on the body, by the aperture of step motor control body by-pass, the air inlet requirement during with the solution idling operation.Finally, (nominal situation and idling operation) reaches desirable air fuel ratio (ratio of air and fuel oil) under various operating modes, and fuel oil is fully burnt, and saves fuel oil, reduces the discharging of tail gas.
In the existing petrol engine electric control fuel oil jet system, the gasoline in the fuel tank is volatile, has certain density gasoline partial pressure in the fuel tank at any time, and during as if the chance hot weather, the increase of gasoline gas bulk concentration reaches explosion limit, then can cause the danger of exploding.Its handling just has only fuel tank is taked cooling measure, as adopting water for cooling to reduce the gasification of gasoline.In addition, also there is not better way.And do not solve the respective design of gasoline vapour emission in the fuel tank on the existing electronic air throttle body yet.
The model utility content
The purpose of this utility model is to provide a kind of novel electrospray throttle valve body to the problem of prior art existence, the gasoline vapour in the fuel tank (also claiming gasification gasoline) is introduced by the road the suction port of throttle body, finally introduces motor and burns.
This novel purpose is realized by following design: a kind of novel electrospray throttle valve body, comprise body, throttle plate pin, throttle blade, swing frame, torsion spring, position transducer, the stepper motor of control body by-pass aperture, body are provided with as the adsorption tube that is communicated with fuel tank, and adsorption tube is communicated with suction port on the body through the body internal channel.
Above-mentioned body is provided with the water-circulating pipe as cooling water circulation.
Because an end face of throttle body directly is connected with the flange surface of motor, basis is novel to be provided with adsorption tube at the throttle body body, the adsorption tube outer end is communicated with fuel tank by the road, adsorption tube suction port inner and on the body is communicated with, like this, can utilize pressure difference, automatically the fuel oil-gas that volatilizees in the fuel tank be introduced engine combustion.On the one hand, can get rid of the fuel oil-gas of volatilization in the fuel tank at any time, eliminate explosion safety hidden danger; On the other hand, simultaneously this part fuel oil-gas is recycled, reduced environmental pollution, saved and utilized fuel.
For solving the cooling problem of throttle body, this novel water-circulating pipe that is provided with on body is lowered the temperature the cooling water introducing, has solved throttle body temperature height rationally and effectively, influences the problem of proper functioning.

Fig. 3 Fig. 4 is respectively B-B and the A-A sectional drawing of Fig. 2;
Fig. 5 is the rear view of Fig. 2.
Embodiment
Fig. 2 Fig. 3 Fig. 4 illustrates, and throttle blade 10 is fixed on the throttle plate pin 7, and throttle plate pin 7 is erected on the body 8 through bearing 5,6.Axial clearance regulation mechanism is: the throttle plate pin 7 in the outside of bearing 5 is provided with a draw-in groove, and a collar 4 is arranged on the draw-in groove, and the thickness of collar is less than the width of draw-in groove.Axial clearance regulation mechanism can control the axial float of throttle plate pin, with the accurate return of assurance throttle blade, and unlikely clamping stagnation.Swing frame 9 is arranged on the throttle plate pin 7, and torsion spring 3 adopts torsion spring (thickness is identical), is enclosed within on the throttle plate pin, so that throttle plate pin is produced a reseting torque.When a torsion spring lost efficacy, another root can replace last torsion spring.Also be provided with the stepper motor 1 of position transducer 2 and control body by-pass aperture on the body.Referring to Fig. 4, body 8 is provided with as the adsorption tube 12 that is communicated with fuel tank, and adsorption tube 12 is communicated with suction port on the body 8 through body 8 internal channel 12a.Adsorption tube 11 is arranged on the body, automobile when idling, throttle blade passage adsorption tube 11 air inlets in off position the time, adsorption tube 11 is seldom opened when flat.Referring to Fig. 1 Fig. 2, body 8 is provided with the water-circulating pipe 13 as cooling water circulation.Referring to Fig. 5, the end face that is connected with motor on the body 8 is provided with two mounting holes 14,14a (existing is 4 mounting holes).
This novel genus the applicant's D46M type throttle body.Its body structure optimization, attractive in appearance.Be carved with client's coding on the body, be carved with the D46M printed words on the throttle blade.
