Spark ignition type in-cylinder injection internal combustion engine

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 comprises a fuel injection valve (21) for directly injecting fuel into a combustion chamber (18), and injects fuel during a compression stroke in a specific operation region under an intermediate to high load so as to perform stratified combustion, further provided is control means (16) for driving and controlling the fuel injection valve (21) such that, in the stratified combustion, prior to the fuel injection during the compression stroke, fuel is injected from the fuel injection valve (21) during an intake stroke by such an amount that fuel fails to self-ignite. <IMAGE>
