摘要： A control system for an internal combustion engine, which is capable of enhancing the accuracy of fuel control and ignition timing control even when there is a possibility that the reliability of a calculated intake air amount lowers, and enables reduction of manufacturing costs. An ECU of the control system calculates a first estimated intake air amount according to a valve lift, a cam phase, and a compression ratio, calculates a second estimated intake air amount according to the flow rate of air detected by an air flow sensor. The ECU determines a fuel injection amount according to the first estimated intake air amount when an estimated flow rate Gin_vt calculated based on an engine speed, the valve lift, the cam phase, and the compression ratio is within the range of Gin_vt≦Gin1, and according to the second estimated intake air amount when Gin2≦Gin_vt.

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.
