摘要:
Provided is an exhaust gas recirculation apparatus of an internal combustion engine which can effectively suppress condensed water from being generated in an EGR passage, compared with the conventional apparatus. The exhaust gas recirculation apparatus includes an EGR pipe formed therein with an EGR passage held in communication with the exhaust passage and the intake passage, an EGR cooler in the EGR passage to cool the EGR gas, a first valve provided in the EGR passage between the EGR cooler and the exhaust passage to selectively take an opened state or a closed state, the first valve being operative to shut off the EGR gas from flowing into the EGR passage when the first valve takes the closed state, a second valve provided in the EGR passage between the EGR cooler and the intake passage to adjust an amount of the EGR gas flowing into the intake passage.
