ABSTRACT:
A feed pump28that is driven by the axial torque of an internal combustion engine10is installed. An electric scavenge pump36is installed. A base value for the ratio (S/F ratio) between the discharge volume of the scavenge pump36and feed pump28is calculated. The base value is corrected so that the S/F ratio is lower in a region where the engine speed is high than in a region where the engine speed is low. The discharge volume of the scavenge pump36is controlled in accordance with the S/F ratio that is corrected in the above manner.
