For making your auditor can be easier to the effect of understanding structure of the present invention and reaching, conjunction with figs. explanation now as back:
At first see also shown in Figure 2; The motorcycle 2 of injection type engines is provided with one in the place ahead of a foot-operated pad 21 and controls handle 22, and this is controlled handle 22 downsides and is pivoted with front-wheel 23; At the rear of foot-operated pad 21 then is the high seat cushion 24 that rises; The below of seat cushion 24 is provided with the containing box 25 that supplies safety helmet or other article to put, and the below of this containing box 25 is an injection type engines 3, and this injection type engines 3 sends power to trailing wheel 26; And can be, and then drive front-wheel 23 and do synchronous rotation and reach the purpose of advancing in the rotation that starts injection type engines 3 rear driving trailing wheels 26.The start flow process of the ejecting system 3a that injection type engines 3 is set; Please cooperate Fig. 3 to consult; Its by a fuel pump 31 with the injection apparatus 34 (that is nozzle) on fuel delivery to the suction tude 33 in the fuel oil fuel tank 32; And by the aperture of the throttle valve 42 of the throttle valve body 41 of a throttle valve 42 aperture perceptrons 35 perception air-flow control devices 4, simultaneously, the temperature and pressure of air in the atmospheric temperature pressure perceptron 36 perception input suction tude 33 of throttle valve body 41 upstream sides; By an electronic control unit 5 control injection apparatus 34 mode of an amount of fuel oil with the mist of oil shape sprayed in the intake duct 38 of injection type engines 3 again, make the fuel oil of mist of oil shape in intake duct 38, mix back entering firing chamber 3b, and send Ignition signal by electronic control unit 5 and control a light a fire device 37 oil gas is lighted with air; Make the reciprocating generation power of piston 3c, make injection type engines 3 starts, again; Throttle valve 42 is linked to the oiling handle (not drawing) of controlling handle 22 places of motorcycle 2 here with traction component; When rotate to refuel after, can spur throttle valve 42 through traction component, make the angle of throttle valve 42 apertures become big; To let more air pass through; Simultaneously electronic control unit 5 is detecting engine speed, the temperature in throttle valve 42 apertures and the suction tude, pressure etc. become because of after, import firing chamber 2B after making an amount of fuel oil of injection apparatus 34 (that is nozzle) ejection and air mixing; Increasing power firing the back, and can do the action of acceleration.
As shown in Figure 4; At least can supply the control device 43 of the throttle valve 42 of traction component connection on the outer circumferential face of this throttle valve body 41; And the assembly department 44 of sub-control unit 5 installations of can supplying power; This assembly department 44 is provided with a plurality of holes 441 that fasten, and this assembly department 44 is provided with the left half 6a (being seen to tailstock direction by headstock) of engine air admittance bypass 6.This electronic control unit 5 have at least one connect port 51, engine air admittance bypass 6 right half 6b, and the screw fixed hole 52 of a plurality of jack holes 441 corresponding to throttle valve 41 assembly departments 44, this connection port 51 can be exported each into RCA and connect.By this, this electronic control unit 5 can be by the solid assembly S of spiral shell, and can be installed on the throttle valve body 41, between electronic control unit 5 and throttle valve body 41, is provided with a leak-proof gasket C, with increase electronic control unit 5 and the tightness after throttle valve body 41 combines.
This engine air admittance bypass 6 mainly is the upstream end 41a that is positioned at the engine air admittance path of throttle valve body 41 by; Offer one run through throttle valve body 41 inlet hole 61; The extraneous fresh air of part that gets in the throttle valve body 41 is imported in the engine air admittance bypass 6; This imports the extraneous fresh air of engine air admittance bypass 6; After its circulation of the control of being located at the control valve 62 of (being the right half 6b of engine air admittance bypass 6) on the electronic control unit 5, again through the downstream 41b place of honeycomb duct 63 by the engine air admittance path that is positioned at throttle valve body 41, offer one run through throttle valve body 41 air outlet hole 64 lead the downstream part of throttle valve body 41.Engine air admittance bypass 6 will get into the extraneous fresh air of the part on the engine air admittance path by this; The throttle valve 42 of walking around throttle valve body 41 comes supply engine when idling, to use; Because this control valve 62 is with the mode of snap switch; Make these engine air admittance bypass 6 conductings and close, avoided this control valve 62 to spread out of because of the noise that operates fast.
Please consult Fig. 4 simultaneously, shown in 5, the present invention avoids this control valve 62 because of the noise of fast running spreads out of, and mainly is at the upstream end 62a of this control valve 62 soundproof member 7 to be set; This soundproof member 7 is when implementing; Can sound absorbing material be set in the inboard of soundproof member 7, be provided with a vent 71 at least on this soundproof member 7, this vent 71 is just corresponding to inlet hole 61; Can let outside fresh air be able to circulation on engine air admittance bypass 6 by this, and can not be interfered or hinder.Setting by this soundproof member 7; Make control valve 62 upstream end 6a originally for than opened state; Become an approximate closed state; Therefore when the noise of control valve 62 was gone out by upstream end 6a tendency to develop, this noise major part will be stopped by this soundproof member 7, can effectively reduce the noise content of this electronic control unit 5 by this.In addition, around the honeycomb duct 63 of control valve 62 downstream part 62b interior, Sound-absorbing member 8 is set,, can reduces the noise content that the noise of control valve 62 is spread out of by control valve 62 downstream part 62b by this like the soft materials of acoustical cotton or other tool sound-absorbing effect etc.
In sum, the effect that the present invention really can promote use by the noise-proof structure of above-mentioned electronic control unit 5, and the important document of novelty, creativeness and practicability; File an application in the whence in accordance with the law; Request your auditor's detailed mirror, bestow authorization, to feeling moral just for granting a patent.
