Abstract
The utility model relates to a throttle body of horizontal engine which is suitable to be used in electric fuel injection type motorcycle. The utility model is characterized in that the shell consists of an oil injection segment shell 2 and a throttle segment shell 5; the two segments of shells are connected with each other through a flange; the external end of the throttle segment shell 5 is connected with an air filter 6; the external end of the oil injection segment shell 2 is connected with an engine cylinder head 1; the oil injection segment shell 2 is communicated with an oil rail 13 through an oil nozzle 18; the throttle 4 is arranged inside the throttle segment shell 5 through a rotating shaft 3; and the external wall of the throttle segment shell 5 is provided with an accelerator pulling wire bracket 16. The utility model is used in accompany with an engine injection system to automatically and temporarily control the oil-gas mixing thickness. Besides, the utility model has the advantages of reliable performance and easy operation.
Description
(1) technical field:
The utility model relates to the closure on a kind of motorcycle, especially is applicable to the throttle body of the horizontal engine of Electronic Fuel Injection (EFI) motorcycle.
(2) background technique:
As everyone knows, what traditional motorcycle engine fuel feeding gas, mixed steam generally adopted is Carburetor, because Carburetor 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, can not make its air fuel ratio accurately be controlled near the theoretical value, make 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.But traditional Carburetor can not adapt to the work of Electronic Fuel Injection (EFI) motorcycle, promptly it can not with the supporting use of motorcycle engine electronic fuel injection system.Chinese patent 012079855 " single cylinder motorcycle throttle body " has solved this problem effectively at present.It can carry out Instantaneous Control to gas concentration according to throttle opening and engine operating condition automatically by electric control device, 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.This throttle body is a straight-through tube owing to housing, thereby can not be applicable to horizontal motorcycle engine, and closure is without runner and acceleration cable and driver's accelerator pedal (throttle) interlock, so it is desirable not enough to quicken the interlock effect.
(3) summary of the invention:
The purpose of this utility model provides a kind of throttle body that is applicable to the horizontal engine of Electronic Fuel Injection (EFI) motorcycle.
Concrete scheme of the present utility model is: comprise rotating shaft, closure, position transducer, spring, idle adjusting screw, torsion spring, runner, oil inlet pipe connect chew, oily rail, return tube connect and chew, oil injecting nozzle and housing, it is characterized in that: housing is made up of the gentle gate segment housing of oil spout piece housing, two-piece housing connects through flange plate, valve piece housing external end head is connected with air-strainer, and the external end head of oil spout piece housing is connected with engine cylinder head; The oil spout piece housing communicates with oily rail through oil injecting nozzle, and closure is installed in the valve piece housing by rotating shaft, and the acceleration cable support is installed on the outer wall of valve piece housing.
Adopt such scheme, can be applicable to horizontal engine, it is convenient simple and direct to quicken control, and 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.
(4) description of drawings:
Fig. 1 is a plan view of the present utility model;
Fig. 2 is the left view of Fig. 1.
(5) embodiment:
Please see Figure 1, Fig. 2, the utility model mainly by oil spout piece housing 2, rotating shaft 3, closure 4, valve piece housing 5, position transducer 7, spring 8, idle adjusting screw 9, torsion spring 10, runner 11, suction tude connect chew 12, oily rail 13, return tube connect chew 14, acceleration cable support 17, oil injecting nozzle 18 form.The part that is connected on the utility model and the former car has engine cylinder head 1, air-strainer 6, fuel supply line 17 and EFI controller 15.The structure outline of model utility is: housing is made up of oil spout piece housing 2 gentle gate segment housings 5, and two-piece housing connects through flange plate, and valve piece housing 5 external end heads are connected with air-strainer 6, and the external end head of oil spout piece housing 2 is connected with engine cylinder head 1; Oil spout piece housing 2 communicates with oily rail 13 through oil injecting nozzle 18, and closure 4 is installed in the valve piece housing 5 by rotating shaft 3, and acceleration cable support 16 is installed on the outer wall of valve piece housing 5.Closure 4 through being installed in rotating shaft 3 one ends runner 11 and pass the acceleration cable of acceleration cable support 16 and be connected with driver's accelerator pedal (throttle).As shown in Figure 2: 3 one of rotating shafts are equipped with runner 11, idle adjusting screw 9 and torsion spring 10, and the two ends of torsion spring 10 are hooked in respectively on 5 of housings and the runner 11, and runner is resetted.Idle adjusting screw 9, spring 8 are contained on the housing 5, the closure of regulator idling operation.The throttle opening size is that the inlet air pathway sectional area changes with engine operating condition.The other end of rotating shaft 3 is equipped with throttle position sensor 7, detects the aperture size of closure 4, in view of the above engine operating condition (idling, full load, acceleration or decelerate) is measured back input EFI controller (ECU) 15.15 1 of EFI controllers (ECU) are connected with throttle position sensor 7, and the other end is connected with oil injecting nozzle 18.As shown in Figure 1: oil spout piece housing 2 is a bend pipe, has the fitting seat hole of dress oil sprayer on oil spout piece housing 2.In conjunction with shown in Figure 2, the oil inlet pipe that the conveying fuel oil is housed on the oily rail 13 connects chews 12, and return tube connects chews 14; And by screw on its bearing.Oil sprayer 18 is promptly installed therebetween, the injected fuel that provides according to EFI controller (ECU) 15.Accurately the oil gas mixed steam of control promptly sprays into engine cylinder head 1 by the throttle body front port.
