PURPOSE:To operate more cylinders and prevent occurrence of output shortage, by temporarily opening a control valve through a signal of performing disengagement operation of a clutch. CONSTITUTION:To perform shifting operation from the neutral position to the first speed shift position, if a clutch pedal 24 is depressed, a solenoid selector valve 12 is turned off through a switch 23, and a pressure chamber 10 in a negative pressure actuator 9 is communicated to the downstream side of a contorl valve 7, then the control valve 7 is opened kand kept opening till the depression of the pdedal 24 is released, during this time an accelerator pedal is depressed to increase a feed of fuel to each cylinder 1. If a throttle valve 6 is further opened by depression of the accelerator pedal, a cam 14 is also turned counter clockwise, if a roller 16 rides on a crest part 14b, a push feed element 18 turns off a switch 15, accordingly the selector valve 12 is demagnetized, and the pressure chamber of the negative pressure actuator 9 is communicated to the downstream side of the control valve 7, then the control valve 7 is opened to feed fuel also to a cylinder 1. |
