PURPOSE:To prevent shock likely to occur, when the fuel is supplied, and to enhance the rate of fuel consumption, by changing the number of revolutions of the engine under deceleration at the starting and finishing time of fuel cut operation in accordance with the gearing position of speed change device. CONSTITUTION:If the gearing position of speed change device is on the high speed side during deceleration of an engine, all of the neutral SW2, clutch SW3, throttle valve SW4 and neg. pressure SW11 are turned off, while a high speed SW on. At this time, a rotation SW5 is turned on under a number of revolution of 1,900rpm, and operation of a slow system cut valve 1 is stopped to resume the fuel supply, but because No.2 rotation SW15 is turned on at 1,700rpm, the valve I is started again. No.2 rotation SW15 is turned off at 1,300rpm, but it is held by No.3 rotation SW12, and No.3 rotation SW12 is turned on at 1,100rpm, so that operation of a cut valve 1 is stopped. If the gearing position is on the low speed side, start and stop of the valve I operation is controlled only by the rotation SW5. |
