ABSTRACT:
An upper level sensor or the like is used to detect an amount of lubricant in an oil pan of an engine. When the amount of lubricant exceeds a prescribed value (step ST1), that is, when lubrication of a sliding portion such as a bearing is insufficient due to dilution of the lubricant with fuel, control for lowering engine output such as control for lowering a maximum combustion pressure (step ST3) is carried out, so that combustion load applied to the sliding portion such as a bearing is suppressed when the maximum combustion pressure is attained and seizure of a connecting rod bearing or the like is prevented.
