Abstract: The ratio between the amount of exhaust gas recirculated by a high-pressure EGR device and the amount of exhaust gas recirculated by a low-pressure EGR device (mixture ratio) is controlled based on the operating state of an internal combustion engine and the correlation between the fuel consumption rate of the internal combustion engine and the mixture ratio. Thus, high-pressure EGR and low-pressure EGR are performed at the mixture ratio (optimum mixture ratio) at which the fuel consumption rate is at or around the minimum value.

Abstract: A variable-geometry turbocharger and a low-pressure EGR passage are provided. The variable-geometry turbocharger includes a turbine provided in an exhaust passage, and a compressor provided in an intake passage. In the variable-geometry turbocharger, the cross sectional area of a path through which exhaust gas passes is adjusted by adjusting the opening degree of a nozzle vane. The low-pressure EGR passage connects the area of the exhaust passage downstream of the turbine to the area of the intake passage upstream of the compressor. The EGR gas is recirculated to the intake passage through the low-pressure EGR passage. The EGR gas is directed to flow through the low-pressure EGR passage when a vehicle is decelerating or when fuel supply to the internal combustion engine is cut off. The pressure in the intake passage is adjusted toward a target pressure by adjusting the opening degree of the nozzle vane when the EGR gas flows through the low-pressure EGR passage.

Abstract: An EGR system includes a high-pressure EGR passage that provides communication between an exhaust pipe, at a portion upstream of a turbine of a turbocharger, and an intake pipe, at a portion downstream of a compressor; a low-pressure EGR passage that provides communication between the exhaust pipe, at a portion downstream of the turbine, and the intake passage, at a portion upstream of the compressor; and an exhaust gas catalyst provided upstream of a position at which the low-pressure EGR passage is connected to the exhaust pipe. When an internal combustion engine is in the transitional state from the low-load operating state to the high-load operating state (S303), if incomplete combustion is detected in the internal combustion engine (S304) and the bed temperature of the exhaust gas catalyst is lower than the reference temperature (S305), the high-pressure EGR gas amount is made larger than the prescribed high-pressure EGR gas amount determined based on the operating state of the internal combustion engine (S306). Thus, an excessive decrease in the intake air temperature is suppressed, and therefore occurrence of incomplete combustion is suppressed.
