PURPOSE:To suppress uncomfortable vibration of a car body at its acceleration, by providing a detector detecting acceleration of an engine to an electronically controlled fuel injection device and stopping supply of fuel partially to a cylinder group for a prescribed time at a start of acceleration to increase torque of the engine in stage. CONSTITUTION:Acceleration is started, if a throttle valve sensor 9 is turned ON, an output of a monostable multivibrator 10 becomes a LOW level for a prescribed time (t), during this time, a driving pulse signal to a fuel injection valve 4 of the second cylinder group 2 is cut off. While a driving pulse signal increasing the pulse width in accordance with a start of acceleration is given in that state to a fuel injection valve 3 of the first cylinder group 1. Accordingly, an engine firstly generates an initial increase of torque in accordance with a fuel quantity increase of the first cylinder group 1, from this on with a delay time about t, an increase of torque by the second cylinder group 2 is generated to perform an increase in two stages. Vibration of a car body caused with this change of torque as a vibrating input can be suppressed by mutual interference between the initial vibration and the vibration caused with delay by the time t. |
