Abstract:
1. An internal combustion engine comprising: a first flow change part that is provided in a first passage that interconnects an inside of a crankcase and a part of an intake passage located at a downstream side of an intake air amount adjustment part adjusting an intake air amount and changes gas flow in the first passage; a second flow change part that is provided in a second passage that interconnects the inside of the crankcase and a part of the intake passage located at an upstream side of the intake air amount adjustment part and changes gas flow in the second passage; and an electronic control unit configured to: execute a feedback control that controls a fuel injection amount, and control the first flow change part to decrease a flow rate of gas passing through the first passage and control the second flow change part to restrict a gas flow direction in the second passage to a direction in which gas flows to the inside of the crankcase from the intake passage, when an engine temperature is higher than a given value and a degree of fuel decreasing correction by the feedback control exceeds a given degree.
