Abstract:
1. A direct fuel injection/spark ignition engine control device comprising: fuel injection controlling means for controlling fuel injections of a fuel injection valve that directly injects fuel into a combustion chamber; and ignition timing controlling means for controlling ignition of a spark plug disposed in the combustion chamber such that an ignition timing is set to ignite fuel at or after a compression top dead center, the fuel injection controlling means being further configured to set a first fuel injection with a first injection start timing and a first injection end timing that both occur in a compression stroke, the fuel injection controlling means being further configured to set a second fuel injection with a second injection start timing and a second injection end timing that both occur in a second half of the compression stroke before the compression top dead center, the fuel injection control means being further configured to set the second injection start timing of the second fuel injection at or after 20° CA before the compression top dead center.
