An air-fuel ratio of an air-fuel mixture produced by fuel injected from a first injector into an intake port (or into a combustion chamber) is set in a range of 28 to 38. Therefore, when the temperature and pressure rise with a first combustion started by spark-ignition around a spark plug to the fuel injected from a second injector into the combustion chamber, the timing of starting a second compressive hypergolic ignition is optimized to provide a stable combustion state free of knocking and misfire.
