摘要:
An exhaust gas recirculation device of an engine (10) of the invention comprises a first exhaust gas recirculation passage (50) for connecting an exhaust passage (40) and an intake passage (30) to each other and introducing into the intake passage an exhaust gas discharged from a combustion chamber (21) to the exhaust passage, and a second exhaust gas recirculation passage (55) for connecting the exhaust passage upstream of a part of the exhaust passage connected to the first exhaust gas recirculation passage and the intake passage downstream of a part of the intake passage connected to the first exhaust gas recirculation passage to each other and introducing into the intake passage the exhaust gas discharged from the combustion chamber to the exhaust passage. The amount of the exhaust gas introduced into the intake passage via the first exhaust gas recirculation passage is controlled to a first target exhaust gas recirculation amount and the amount of the exhaust gas introduced into the intake passage via the second exhaust gas recirculation passage is controlled to a second target exhaust gas recirculation amount. The amount of exhaust gas introduced into the first and second exhaust gas passages is controlled in accordance with an allowable upper flame temperature.
