PURPOSE:To perform the same control without reference to engine performance by comparing the set value of negative suction pressure, which varies with the extent of opening of a throttle value, with measured negative suction pressure, and then performing control by half the measured negative suction pressure at every time in such a way that both the values become coincident with each other. CONSTITUTION:In a control system for the extent of opening of a throttle valve, a processor 8 is connected to a parameter setter 1 and a throttle controller 5 is connected to the processor 8 through a servo amplifier 4. A carburetion throttle valve 6 is fitted to the throttle controller 5, whose opening extent value is detected by a parameter detector 7 and inputted to the processor 8. The processor 8 compares the set value from the parameter 1 with the detected value from the detector 7 and increases or decreases the extent of opening of the throttle value by a half at every time in such a way that the set negative suction pressure becomes equal to the measured negative suction pressure. |
