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： An evaporated fuel treatment apparatus collects vapor, generated in a fuel tank, in a canister. A bypass passage is provided for an intake passage. An ejector is placed in the bypass passage to generate a negative pressure by air flowing in the bypass passage. When the negative pressure occurs in the ejector, the vapor collected in the canister is drawn from the canister to the ejector through the purge passage and then purged from the bypass passage to the intake passage. An open/close valve placed in the ejector is configured to allow or block the flow of air from the intake passage to the bypass passage according to a pressure difference between the pressure in an upstream portion and the pressure in a downstream portion of the bypass passage during engine operation.

摘要： A blowby gas returning device is arranged to allow blowby gas leaking from a combustion chamber of an engine to flow in an intake passage through a returning passage and return to the combustion chamber, and arranged to regulate a flow rate of the blowby gas by a PCV valve provided in the returning passage. This blowby gas returning device comprises an outside-air passage for mixing outside air into the blowby gas before being introduced into the PCV valve; and an open-close valve for opening and closing the outside-air passage. An electronic control unit controls the open-close valve to open when the operating state detected by sensors is an idle state.
