ABSTRACT:
If it is determined that the present engine startup is a high-temperature startup, immediately fuel injection in concert with start of cranking is prohibited. After a delay time elapses following the start of cranking, or when THC<THCh is satisfied, fuel injection is started. Therefore, the cranking during the delay time cools interior of the combustion chambers. Since fuel injection starts after the cooling, pre-ignition can be prevented.
