Patent ID: 7043914

Claim:
An EGR system for an internal combustion engine with a turbo-charger, comprising a first EGR passage for recirculating a part of exhaust gas from the upstream side of a turbine of the turbo-charger to the downstream side of a compressor of the turbo-charger, a second EGR passage for recirculating a part of the exhaust gas from the downstream side of said turbine to the upstream side of said compressor, an exhaust gas purifying apparatus with a first diesel particulate filter, a flow control means for controlling the exhaust gas flow in said first EGR passage and said second EGR passage and an EGR control means for controlling the flow control means based on data detected by an exhaust gas state monitoring means, wherein a second diesel particulate filter is arranged in said second EGR passage, and the second EGR passage has an inlet disposed on the upstream side of the first diesel particulate filter.
