Abstract
An EGR system for an internal combustion engine provided with a first EGR passage for recirculating EGR gas to the downstream side of a compressor from the upstream side of a turbine of a turbo-charger is provided with a second EGR passage for recirculating EGR gas from the downstream side of the turbine to the upstream side of the EGR gas, and provided also with a DPF in the second EGR passage, while the exhaust gas flow in the first EGR passage and the second EGR passage is controlled based on the exhaust gas temperature detected by an exhaust gas temperature sensor arranged in the exhaust gas passage.
