Technical Examples

A feed pump 28 that is driven by the axial torque of an internal combustion engine 10 is installed. An electric scavenge pump 36 is installed. A base value for the ratio (S/F ratio) between the discharge volume of the scavenge pump 36 and feed pump 28 is 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 pump 36 is controlled in accordance with the S/F ratio that is corrected in the above manner.
