[embodiment]

For making your auditor can be easier to effect of understanding structure of the present invention and can reaching, hereby coordinate brief description of the drawings as rear:

First refer to shown in Fig. 3, with regard to the motorcycle 2 of injection type engines, be provided with a manipulation handle 22 in the front of a pedal pad 21, these manipulation handle 22 downsides are pivoted with front-wheel 23, be raised seat cushion 24 at the rear of pedal pad 21, the below of seat cushion 24 is provided with the containing box 25 that supplies safety helmet or other article to put, the below of this containing box 25 is injection type engines 3, this injection type engines 3 sends power to trailing wheel 26, and can be in the rotation that starts injection type engines 3 rear driving trailing wheels 26, and then drive front-wheel 23 to do synchronous rotation to reach the object of advancing.On injection type engines 3, establish the start flow process with ejecting system 3a, please coordinate Fig. 4 to consult, its by a fuel pump 31 by the fuel delivery in a fuel oil box 32 to the injection apparatus 34 (that is nozzle) in suction tude 33, and by the aperture of the throttle valve 42 of the throttle valve body 41 of throttle valve opening perceptron 35 perception air-flow control devices 4, meanwhile, input the temperature and pressure of suction tude 33 interior air in atmospheric temperature pressure perceptron 37 perception of throttle valve body 41 upstream sides, controlling injection apparatus 34 by an electronic control unit 5 again sprays into appropriate fuel oil in the intake duct 38 of injection type engines 3 in the mode of mist of oil shape, after being mixed in intake duct 38 with air, the fuel oil of mist of oil shape enters firing chamber 3b, and send Ignition signal control one ignition mechanism 37 by electronic control unit 5 oil gas is lighted, make the reciprocating generation power of piston 3c, make injection type engines 3 starts, again, throttle valve 42 is linked to the Refueling handle (not drawing) at manipulation handle 22 places of motorcycle 2 herein with traction component, when rotating after Refueling handle, can pull throttle valve 42 through traction component, make the angle of throttle valve 42 sections of opening become large, to allow more air pass through, electronic control unit 5 is detecting engine speed simultaneously, temperature in throttle valve opening and suction tude, pressure etc. become because of after, make injection apparatus 34 (that is nozzle) spray appropriate fuel oil and mix rear input firing chamber 3b with air, to increase power after firing, and can do the action of accelerating.

Refer to shown in Fig. 5, the control device 43 of throttle valve 42 that at least can connect for traction component on the outer circumferential face of this throttle valve body 41, and the assembly department 44 of can supplied for electronic control unit 5 installing, this assembly department 44 is provided with multiple jack holes 441.This electronic control unit 5 at least has a connection port 51, engine air admittance bypass 52, and the screw fixed hole 53 of multiple jack hole 441 corresponding to throttle valve 41 assembly departments 44, and this connection port 51 can connect each import and export RCA.By this, this electronic control unit 5 can be consolidated assembly S by spiral shell, and can be installed on throttle valve body 41, is provided with a leak-proof gasket 6, to increase the tightness after electronic control unit 5 and throttle valve body 41 combinations between electronic control unit 5 and throttle valve body 41.

Separately as shown in Figure 6,7, when this electronic control unit 5 is installed on throttle valve body 41, become with the center line 5a of this electronic control unit 5 and the center line 41a of throttle valve body 41, and become one 15 degree to the angle modes of 25 degree to be installed on throttle valve body 41, this electronic control unit 5 is to become skewed mode to be installed on throttle valve body 41 by this, and as shown in Figure 7, dispose the throttle valve body 41 of electronic control unit 5, be just arranged within the scope of the outer periphery of lug boss 251 of containing box 25 bottoms.Because this electronic control unit 5 is to become skewed mode to be installed on throttle valve body 41, therefore can make the upper end portion 54 of this electronic control unit 5 tilt to assembly department 44 opposite sides of throttle valve body 41, and can slightly upwards kick up in the underpart 55 of this electronic control unit 5, can make by this height of end 54 on electronic control unit 5 be minimized, this Port 51 can become down mode and arrange, and makes the underpart 55 of electronic control unit 5 keep suitable spacing with the crankcase of injection type engines 3 30.By aforesaid way, electronic control unit 5 is configured on throttle valve body 41, and throttle valve body 41 and electronic control unit 5 are arranged within the scope of the outer periphery of lug boss 251 of containing box 25 bottoms, the protruding space that can make full use of this lug boss 251 is effectively accommodating, throttle valve body 41 and electronic control unit 5 assemblies, and be configured in throttle valve body 41 by 5 one-tenth skewed modes of this electronic control unit, the restrictive condition that can make containing box 25 affect accommodation space is by this down to minimum, to obtain larger accommodation space.Be configured in throttle valve body 41 by 5 one-tenth skewed modes of this electronic control unit simultaneously, make 51 of this Ports can become direction setting down, therefore this Port 51 is reduced accumulation and the erosion of dust and moisture, and then can make this electronic control unit 5 keep preferably operational function.Separately, be configured in throttle valve body 41 by 5 one-tenth skewed modes of this electronic control unit, can make the underpart 55 of electronic control unit 5 keep suitable spacing with the crankcase of injection type engines 3 30, with the high temperature of crankcase 30 that reduces injection type engines 3, electronic control unit 5 is impacted, the same electronic control unit 5 that makes can keep its preferably operational function.

In sum, the present invention really can promote effect of use by the arrangement of above-mentioned electronic control unit 5, and the important document of novelty, creativeness and practicability, file an application in whence in accordance with the law, request your auditor's mirror in detail, bestow the authorization for granting a patent, to feeling moral just.
