PURPOSE:To positively prevent hunting by interrupting the fuel supply during a period in which the fuel is in a valve more than the set value in accordance with the suction pipe absolute pressure and providing a hysteresis to the set value. CONSTITUTION:A fuel cut valve 4 is actuated only by a software at a control unit 15 by use of a signal MAP from a suction pipe to perform the fuel cut control corresponding to the driving conditions and hysteresis. Further, a hysteresis is provided between the set value of the absolute pressure of the suction pipe to be cut and the set value to be recovered, and the setting is performed by a software. For instance, the hysteresis is provided between the absolute pressure of cutting suction pipe 190mm.Hg abs and the recovering absolute pressure 220mm.Hg abs, whereby the hunting is prevented. |
