PURPOSE:To reduce the torque shock by providing a partial cylinder injection cut region between a normal injection region and an all cylinder injection cut region. CONSTITUTION:The output from a rotation sensor 13 detecting the rotations of an engine 1 and the output from a throttle sensor 12 detecting the aperture of the throttle valve 6 are inputted to a fuel injection cylinder decision unit 14, and the fuel injection of all cylinders is cut off when the load condition is equal to or lower than the first load line rising from an engine speed which is lower than the no-load line of the engine 1 and is higher than an idle engine speed. On the other hand, when the load condition is lower than the no-load line and higher than the first load line, a partial cylinder injection cut region cutting off the fuel injection of partial cylinders is provided between a normal injection region and an all cylinder injection cut region during deceleration to reduce the torque shock. |
