摘要： 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 turbo charger, 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 (S3O3), 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.

摘要： The ratio (R) 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 (1) and the correlation between the fuel consumption rate (SFC) of the internal combustion engine and the mixture ratio (R). 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.

摘要： An EGR system includes a high-pressure EGR unit and a low-pressure EGR unit. During the steady operation of an internal combustion engine, the high-pressure EGR gas and the low-pressure EGR gas are mixed with each other at a mixture ratio, in which the ratio of the high-pressure EGR gas amount to the entire EGR gas amount is higher than that in a known mixture ratio, and then recirculated back to the internal combustion engine. In the engine speed-up transitional operation period, the opening amount of a high-pressure EGR valve is adjusted to the opening amount Oht2 that is much smaller than the target opening amount Ohsfc2 corresponding to the target operation mode. Thus, it is possible to suppress occurrence of the situation where the entire EGR gas amount is excessive in the period Δt23 in which the low-pressure EGR gas amount does not decrease by a sufficient amount.
