PURPOSE:To prevent idling, engine-braking, and other waste works by closing a throttle-closer according to the output of a clutch-stroke sensor even if an accelerator pedal is stepped in by different strokes. CONSTITUTION:When a primary valve 1 of a carburetter is operated through a rod 19, an arm 16, a shaft 14, and others in the linkage of an accelerator pedal, the degree of its opening is detected by a sensor 29, and input into a comparator 35 in a control circuit 33 together with the signal from a clutch-stroke sensor 34. The deviation signal in the comparator 35 is added to an NOR circuit 39, and compared with a clutch cutting signal 38. That is, when the cutting signal 38 and the output of the cutting signal 38 are in low levels at the time of speed changing, the NOR circuit 39 gives a high level output, and excites a solenoid 25a through a transistor 42. Consequently, a closing electromagnetic valve 25 is opened, and the valve 1 is closed through an actuator 5. |
