摘要

PROBLEM TO BE SOLVED: To provide an oil dilution suppressing device for a cylinder direct injection type engine which can suppress oil dilution and fuel dilution, also in an engine having a supercharger.

SOLUTION: The oil dilution suppressing device is a device to suppress oil dilution in a cylinder direct injection type engine having a turbo supercharger (30) and comprises a temperature measuring means (52) to measure an engine temperature; and a supercharge control device to effect correction such that a supercharge pressure by the turbo supercharger set according to the operation state of the cylinder direct injection type engine is reduced in a case that a temperature measured by the temperature measuring means is lower than a prescribed temperature.
