摘要： An object is to prevent deterioration in both exhaust emission and fuel efficiency by suitably combining OTP boosting with power boosting. An electronic control unit (ECU) 30 of the present invention is arranged to control a fuel injection amount of an injector 7 to an engine 1 according to an operating condition of the engine 1, and perform OTP boosting of the fuel injection amount to prevent overheating of a discharge passage 3 and a catalyst converter 11 when the engine 1 comes into a high load and high rotation operating condition and perform power boosting that increases the fuel injection amount to enrich an air-fuel ratio to an output air-fuel ratio when the engine 1 comes into a high load operating condition. The ECU 30 executes the power boosting when the engine 1 comes into the high load and high rotation operating condition and executes the OTP boosting later from the start of the power boosting, delayed by a period attributable to at least an increased amount of fuel by the power boosting.

摘要： A blow-by gas refluxing device is provided for an engine system including an engine and an intake air passage communicating with the engine for supplying intake air into the engine. The blow-by gas refluxing device includes a plurality of blow-by gas refluxing passages each having an inlet communicating with the engine and an outlet communicating with the intake air passage. The outlets of the blow-by gas passages communicate with the intake air passage at different positions along the length of the intake air passage and each of the blow-by gas passages has a backflow preventing device disposed therein, so that blow-by gas produced in the engine can flow into the intake air passage via at least one of the blow-by gas refluxing passages throughout the entire operational range of the engine.
