摘要： In order to securely prevent knocks from occurring upon starting and the like, while enhancing the compression ratio in a spark ignition type in-cylinder injection internal combustion engine which includes a fuel injection valve for directly injecting fuel into a combustion chamber, fuel is injected during a compression stroke in a specific operation region under an intermediate to high load to perform stratified combustion. Further provided is a control unit for driving and controlling the fuel injection valve such that, in the stratified combustion, prior to the fuel injection during the compression stroke, fuel is injected from the fuel injection valve during an intake stroke by such an amount that fuel fails to self-ignite.
