Abstract: PURPOSE:To optimize an interval between fuel injection timing of fuel injection and ignition timing in compression stroke and obtain excellent ignition and combustion by delaying the ignition timing when knocking is occurred, and also delaying the injection timing of the fuel injection in the compression stroke. CONSTITUTION:In the case of operating an engine, in the first place, the total fuel injection volume Q is calculated by means of an ECU 30 according to engine rotation speed and accel opening, and next, compression stroke fuel injection volume Qc is calculated according to the total fuel injection volume Q. Furthermore, according to a map, map ignition timing thetaigM is calculated. Next, a judgment is made on whether or not knocking is occurred, and when the knocking has been occurred, actual ignition timing thetaig is decreased by theta. Next, a judgment is made on whether or not Qc>0 is realized, and when Qc>0 is realized, that is, when compression stroke injection is carried out, compression stroke fuel injection timing thetac is calculated so that the compression stroke fuel injection timing can be delayed. Furthermore, a judgment is made on whether or not the compression stroke fuel injection volume Qc exceeds the maximum value QcMAX, and in the case of Qc>QcMAX, Qc is set as QcMAX.
