The utility model relates to an air throttle valve for a single-cylinder motorcycle. The structural characteristic of the utility model is that an air throttle valve 3 is installed in a housing body 2 and is fixed on a rotating shaft 7 via screws, and the rotating shaft 7 penetrates through the housing body 2 in a radial direction; one end of the rotating shaft 7 is provided with an opening adjusting wheel 6, and the other end is connected with a position sensor 4; a return spring 8 is sheathed on the rotating shaft 7, and the return spring 8 is positioned between the housing body 2 and the opening adjusting wheel 6; an adjusting screw 9 is installed on the housing body 2, an oil supply supporting base 15 for an oil sprayer is arranged above the housing body 2; the oil supply supporting base 15 for the oil sprayer is communicated with housing body via the oil sprayer 11, and an oil pipe joint 12 on the oil supply supporting base 15 for the oil sprayer is connected with an oil pipe 14 of a fuel oil pump on original vehicle. The utility model which is matched with an electronic fuel injection system of a motorcycle engine can automatically carry out the transient control to the concentration of an oil and gas mixture; the utility model can replace a traditional carburetor, and the air-fuel ratio can be accurately controlled. The utility model has the advantages of compact structure, reasonable structure, and reliable operation.
Description
The utility model relates to the closure on a kind of motorcycle, especially single cylinder motorcycle throttle body.
At present, what motorcycle engine fuel feeding gas mixed steam generally adopted is traditional Carburetor, because it is by the control of the adjustment metering-orifice on Carburetor fuel delivery, therefore, it can not carry out Instantaneous Control to oil gas mixed steam concentration automatically with the variation of engine operating condition and environment, its air fuel ratio accurately is controlled near the theoretical value, makes mixed steam or overrich or rare excessively, thereby can not satisfy of the requirement of current various rules motor Economy and the control of exhaust contaminant content.In order to overcome the fuel feeding shortcoming that Carburetor brings, there is the motorcycle engine electronic fuel injection system to come out recently, it can satisfy the requirement of accurate control.
The purpose of this utility model provides a kind of and the matching used single cylinder motorcycle of motorcycle engine electronic fuel injection system throttle body, replaces traditional Carburetor with it, makes it satisfy the accurately requirement of control.
Concrete scheme of the present utility model is: closure is installed in the housing, and is screwed in rotating shaft, and housing is radially passed in rotating shaft; One end of rotating shaft is installed the aperture regulating wheel, and the other end is connected with position transducer; Be set with return spring in rotating shaft, this return spring is between housing and aperture regulating wheel; Initial adjustment screw is installed on housing, and the inserting end of this screw contacts with rotating shaft; Be provided with oil sprayer fuel feeding bearing above housing, this oil sprayer fuel feeding bearing communicates with housing through oil sprayer, and the oil pipe on the oil sprayer fuel feeding bearing connects the fuel pump oil pipe of chewing with on the former car and links to each other.
Adopt such scheme, the available electron control gear carries out Instantaneous Control to gas concentration automatically according to throttle opening and engine operating condition, replace Carburetor, its air fuel ratio is controlled near the theoretical value accurately, satisfies of the requirement of current various rules motor Economy and the control of exhaust contaminant content.It is rational in infrastructure, compact, reliable operation, dismounting, easy to maintenance.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the left view of Fig. 1.
Please see Figure 1, Fig. 2, the utility model mainly by housing 2, closure 3, position transducer 4, air-strainer 5, aperture regulating wheel 6, rotating shaft 7, return spring 8, initially adjust screw 9, tightening spring 10, oil sprayer 11, oil pipe connect chew 12, oil sprayer fuel feeding bearing 15 forms.This model utility and the supporting use of motorcycle engine electronic fuel injection system, wherein position transducer 4 and oil sprayer 11 are connected with electric control device 13 in the motorcycle engine electronic fuel injection system, one end of closure housing 2 is connected with engine cylinder head 1 on the former car, and the air-strainer 5 of the motor on the other end and the former car is connected.Structure characteristic of the present utility model is: closure 3 is installed in the housing 2, and is screwed in rotating shaft 7, and housing 2 is radially passed in rotating shaft 7; One end of rotating shaft 7 is installed aperture regulating wheel 6, and the other end is connected with position transducer 4; Be set with return spring 8 in rotating shaft 7, this return spring 8 is between housing 2 and aperture regulating wheel 6; Initial adjustment screw 9 is installed on housing 2, and the inserting end of this screw 9 contacts with rotating shaft 7; Be provided with oil sprayer fuel feeding bearing 15 above housing 2, this oil sprayer fuel feeding bearing 15 communicates with housing 2 through oil sprayer 11, and the oil pipe on the oil sprayer fuel feeding bearing 15 connects to be chewed 12 and link to each other with fuel pump oil pipe 14 on the former car.
As can be seen from Figure 1: oil sprayer 11 1 ends are connected with oil sprayer fuel feeding bearing 15, and the other end is connected with housing 2.
Also can see from Fig. 2: be sleeved on the boss that return spring 8 one ends in the rotating shaft 7 block the housing 2 of closure, the other end blocks the convex edge of the aperture regulating wheel 6 of closure.Be set with tightening spring 10 initial the adjustment on the screw 9.
The utility model is performed such work: the position transducer 4 of closure links with closure 3, detects the size of closure 3 apertures.The initial position of throttle position sensor 4 (closure 3 contract fullys) is adjusted by initial adjustment screw 9, by 10 tightenings of tightening spring; Each working position of closure 3 is stable by return spring 8.Position transducer is measured input electric control device 13 in back to engine operating condition (idling, full load, acceleration or decelerate) in view of the above.13 pairs of input signals of this electric control device carry out calculation process, determine best fuel injection quantity that satisfies engine operating condition etc. according to ideal air-fuel ratio, and injection signal as a result are sent to the outlet end of oil sprayer 11.Fuel oil connects through fuel pump oil pipe 14, oil pipe and chews 12, oil sprayer fuel feeding bearing 15, supplies with oil sprayer 11.The injection signal injected fuel that oil sprayer 11 provides according to electric control device 13; Accurately the oil gas mixed steam of control is promptly sprayed into the suction port of engine cylinder head 1 by closure housing 2.
