Abstract:
A control apparatus for an in-cylinder injection spark-ignition internal combustion engine, which has a fuel injection valve for injecting fuel directly into a combustion chamber, and in which the fuel is injected mainly in a compression stroke, thereby undergoing stratified-charge combustion, when the internal combustion engine is operated in a specified operation region, comprising:target load setting means for setting a target load value corresponding to accelerator opening information based at least on a driver's operation;environmental parameter value detecting means for detecting environmental parameter values correlated with an intake air density;discriminating means for discriminating that the internal combustion engine is being operated in a compression-stroke injection mode based on said set target load value;target load correcting means for correcting the set target load value based on the detected environmental parameter values when said discriminating means discriminates that the internal combustion engine is being operated in the compression-stroke injection mode;first control parameter value setting means for setting at least one engine control parameter value including at least one of a fuel injection timing and an ignition timing in accordance with the corrected target load value; andcontrol means for executing said stratified-charge combustion in accordance with the set at least one engine control parameter value.
