    摘要： There is provided a control system for an internal combustion engine, which is capable of matching an output torque of the engine with a demanded torque excellently when the combustion mode is switched, thereby enhancing drivability. A demanded fuel amount and a demanded torque of the engine are calculated according to detected operating conditions of the engine. A combustion mode is determined to be either the stratified combustion mode or the homogeneous combustion mode according to the demanded torque. A pre-switching demanded fuel injection time period and a pre-switching demanded torque are stored. When the combustion mode is switched, a switching-time demanded fuel amount (limit value) is calculated according to the stored pre-switching demanded fuel injection time period and pre-switching demanded torque, the current demanded torque, and an estimated combustion efficiency parameter.

    摘要： A control system for an internal combustion engine, which is capable of ensuring excellent fuel economy of the engine and enhancing the responsiveness of the output of the engine when acceleration is demanded. The control system calculates a lift control input for controlling a variable valve lift mechanism, based on a cam phase of a variable cam phase mechanism, and calculates a demanded acceleration indicative of the degree of acceleration demanded of the engine. Further, the control system calculates a value of phase control input for controlling the variable cam phase mechanism with priority to the engine output, and calculates a value of the same with priority to fuel economy of the engine, and selects between the values of phase control input, based on the demanded acceleration.
