Actuating and generating device 250 in this internal-combustion engine 200 has above-mentioned structure, internal rotor 251 rotates with bent axle 201 with being integral, when rotating speed is that the desired speed of not enough idling speed is when following, speed governing inner ring 258 and brush carrier 262 are positioned at right-hand shown in solid line among Fig. 2, and brush 263 contacts with major diameter conducting wire 266, commutator segment 267, the minor diameter conducting wire 268 of rectification stroma 265.And when rotating speed had surpassed desired speed, shown in double dot dash line among Fig. 2, speed regulating mechanism made brush carrier 262 slide to left, and brush 263 leaves major diameter conduction road 266, commutator segment 267, minor diameter conduction road 268.

Therefore, when internal-combustion engine 200 startings, contacting of the major diameter conducting wire 266 of the electric power of battery by brush 263 and rectification stroma 265, commutator segment 267, minor diameter conducting wire 268, supply with actuating coil 273, electric current by the actuating coil 273 of flowing through makes internal rotor 251 produce running torque, directly make bent axle 201 rotations, thereby make engine starting.

And, when bent axle 201 surpasses desired speed, the supply of electric power is stopped by speed regulating mechanism.

Below, illustrate that with reference to Fig. 3 the start control system of internal-combustion engine 200, this internal-combustion engine are provided with the above-mentioned actuating and generating device 250 that directly makes bent axle 201 rotations.

The plus end of battery 50,1 fixed contact 62a with the throttle switch 62 of CDI (capacity discharge igniting) unit 52 and administration of power supply 60 is connected by integral switch 51, and the while, 1 contact 63a with the starting magnetic switch 63 of administration of power supply 60 was connected.

Throttle switch 62 is located on the above-mentioned accelerator device handle 61, is made of fixed contact 62a and circular arc contact 62b, and this circular arc contact 62b is with 61 rotations of accelerator handle.Two contact 62a, 62b are dissengaged positions when the closure full cut-off, are on-state in addition.

Circular arc contact 62b is connected with the electromagnetic coil 63c of starting magnetic switch 63, and the other end of electromagnetic coil 63c is by brake switch 64 ground connection.

Another contact 63b of starting magnetic switch 63 is connected with the minor diameter conducting wire 268 of actuating and generating device 250, and 1 input terminal of while with the NOR loop 71 of igniting shut-down mechanism 70 is connected.

Promptly, when connecting integral switch 51, implement braking and connecting brake switch 64, rotating operation accelerator handle 61, when removing the full-shut position of closure, administration of power supply 60 makes electric current flow through electromagnetic coil 63c, and conducting starting magnetic switch 63 is supplied with actuating and generating device 250 to electric power, drive and start as starter motor, simultaneously to 1 input terminal output H (height) energy level signal in the NOR loop 71 of igniting shut-down mechanism 70.

Therefore, do not have the such member of starter button, under braking state,, just can carry out the starting of internal-combustion engine at once as long as rotate accelerator handle 61, inoperative at state in addition.

On the other hand, another input terminal in NOR loop 71 to igniting shut-down mechanism 70, whether the input expression speed of a motor vehicle is the signal of zero (being whether vehicle speed sensor 53 detected front-wheels 13 rotate), if the speed of a motor vehicle is zero, input L (low) energy level signal, if the speed of a motor vehicle is non-vanishing, input H (height) energy level signal.

Output with NOR loop 71, be input to 1 input terminal in the NAND loop 72 of next stage, another input terminal in this NAND loop 72, the signal that whether finishes of input warming up (promptly being contained in the signal that switches on or off of two starters 55 on the Carburetor 24), if warming up does not finish, then import L (low) energy level signal,, then import H (height) energy level signal if be through with.

The Out let in this NAND loop 72 is connected with the base terminal of transistor 73.

The current-collecting terminals of the transistor 73 of igniting shut-down mechanism 70 is connected with the output of above-mentioned CDI unit 52, and emitter terminal is connected with the spark coil 54 that makes igniter plug 206 actions.

Igniting shut-down mechanism 70 is as constitute above-mentionedly, at throttle opening is that full cut-off, the speed of a motor vehicle are when being zero, any one all imports L (low) energy level signal in 2 input terminals in NOR loop 71, H (height) energy level signal is input to NAND loop 72, and, when warming up finishes, on another input terminal in NAND loop 72, input H energy level signal, therefore, the 72 output L energy level signals from the NAND loop, the base terminal of transistor 73 becomes the L energy level, form non-conduction, from the CDI unit 52 output initial firing currents do not flow to spark coil 54, igniting is stopped.

Even at throttle opening is that full cut-off, the speed of a motor vehicle are zero, warming up finishes a state is arranged not simultaneously in these three kinds of states, NAND loop 72 is output as the H energy level, transistor 73 conductings, and becoming can fired state.

This start control system is owing to have above-mentioned formation, so, when motor bike 1 stops after travelling, operation accelerator handle 61, with the throttle opening full cut-off, brake, car is stopped, the speed of a motor vehicle is zero, owing to be in warming up done state, so igniting shut-down mechanism 70 stops igniting, the running of internal-combustion engine is stopped.

Even during because of temporary transient parkings such as traffic light signals, the running of internal-combustion engine also is stopped, and can avoid the waste of fuel.

Under braking state (brake switch 64 on-states), operation accelerator handle 61, during the opening throttle aperture, make 63 conductings of starting magnetic switch, electric power is supplied with the actuating coil 273 of actuating and generating device 250, begin starting as the driving of starter motor, simultaneously, 1 input terminal output H energy level signal to the NOR loop 71 of igniting shut-down mechanism 70 makes transistor 73 conductings, thereby make igniter plug 206 igniting, make internal-combustion engine 200 startings.

Because this actuating and generating device 250 directly makes bent axle 201 rotations start, so, can make the rotation of 201 moments of bent axle and noise free ground, can successfully carry out the starting of internal-combustion engine 200.

After internal-combustion engine 200 starting, when bent axle 201 surpasses desired speed, stopped to actuating and generating device 250 supply capabilities by speed regulating mechanism, internal-combustion engine rotational speed moment ground rises to the throttle opening of operating according to quickening.

As mentioned above, because after temporary transient the parking, as long as operation accelerator handle 61, just starting of internal-combustion engine 200 is risen internal-combustion engine rotational speed, so, as long as the centrifugal clutch of trailing wheel 21 sides also connects, brake off just can start immediately.

That is, when each temporary transient the parking, the running of internal-combustion engine 200 also stops, and can avoid the waste of fuel, simultaneously can with shirtsleeve operation can be immediately, starting successfully.

Igniting shut-down mechanism 70, as when temporary transient the parking throttle opening be full cut-off, the speed of a motor vehicle be zero and warming up stop igniting when finishing, when engine starting, need under the situation of warming up, before warming up finishes, constant ignition does not stop the running of internal-combustion engine always.

In this start control system, brake switch 64 in series is contained on the electromagnetic coil 63c of starting magnetic switch 63, make and to start in braking state, though can not promptly travel for thirty years of age by the starting of internal-combustion engine, but, in this motor bike, also can this brake switch 64 be contained on the electromagnetic coil 63c of starting magnetic switch 63, and make electromagnetic coil 63 direct ground connection, so can not occur hindering yet.

That is, the wobble component 17 of this motor bike 1 is owing to make the rotation of bent axle 201 be delivered to trailing wheel 21 by belt type continuously variable transmission 35 and centrifugal clutch.So, even actuating and generating device 250 directly makes bent axle 201 rotations as starter motor, before reaching the rotating speed that makes the centrifugal clutch connection, trailing wheel 21 rotations are travelled, so, brake switch 64 is not installed is had no relations yet.

In the present embodiment, the end of internal-combustion engine warming up is to detect by the having or not of action that is located at the two starters 55 on the Carburetor 24.But, also can detect warming up and whether finish by to the rising of internal-combustion engine water temperature, to the supervision of the involution of the choker operation of Carburetor etc.
