摘要： An exhaust gas recirculation device capable of restraining generation of condensate water in an EGR path after engine stoppage is provided. When ignition is switched from ON to OFF, fuel injection is prohibited. As a result, a gas (fresh air) that flows into a cylinder after the switching is discharged into an exhaust passage 14 without burning. In the present invention, a valve opening timing EVO of an exhaust valve is changed so that a high peak portion of a pulsation of the gas arises at an EGR branch point, and the EGR valve 32 is opened. Thereby, the fresh air flowing in the exhaust passage 14 can be introduced into an EGR passage 28, and therefore an EGR gas in the EGR passage 28 can be replaced with the fresh air.

摘要： A control system of a Miller cycle engine (10) includes an ECU (50). The ECU executes an early closing Miller cycle operating mode in which a variable valve mechanism (38) is controlled to close an intake valve (36) before an intake bottom dead center (BDC). The ECU executes a decompression mode in which the variable valve mechanism is controlled to close the intake valve at a point later than the intake BDC, when the engine is started. The ECU executes the early closing Miller cycle operating mode after completion of the decompression mode. A later closing amount of the intake valve relative to the intake BDC, for use in the decompression mode, is larger than an early closing amount of the intake valve relative to the intake BDC when the closing timing of the intake valve is most advanced.
