Abstract: PURPOSE:To suppress knocking without using any knock sensor and the like and to suppress worsening of fuel consumption. CONSTITUTION:An opening/closing timing of an intake valve is altered by driving a VVT 23 by an oil pressure. An ECU 70 computes a driving area of an engine 1 on the basis of signals of an air flow meter 62, a rotational speed sensor 66, and the like. When the computed result is in a low relation and load area or a low rotation and high load area, the opening/closing timing of the intake valve 8 drives the VVT 23 for spark-advance. On the other hand, when the computed result is in a low rotation and medium load area or in an area of more than medium rotation, the VVT 23 is driven so as to delay the opening/closing timing of the intake valve 8. Therefore, the opening/closing timing of the intake valve 8 is delayed in a low rotation and medium load driving area, in which knocking is likely to happen, so that an intake air, which tends to escape after being introduced into a combustion chamber 4 once, is increased, and consequently, the intake air amount is reduced and an effective compression ratio is reduced.

Abstract: PURPOSE:To enable change of a fuel injection time according to the torque fluctuation amount of an internal combustion engine, in a device for controlling the fuel injection time of a multiple cylinder internal combustion engine for lean limit control. CONSTITUTION:A torque fluctuation value is detected (step 101 to 108), and it is judged whether the detected torque fluctuation value is in a prescribed value range or not, (step 110). When the torque fluctuation value is a lower limit value or less, a fuel injection completed time is advanced (step 111). When the torque fluctuation value is an upper limit value or more, the fuel injection completed time is delayed (step 112).
