An internal combustion engine provided with an exhaust gas recirculation device is configured so that the exhaust gas from a specific cylinder is recirculated to the air intake path, and the configuration enables the amount of recirculated exhaust gas to be adjusted with high reliability. An internal combustion engine provided with an exhaust gas recirculation device comprises a first exhaust gas discharge port (30a) which is provided to a cylinder (D) (specific cylinder) of the internal combustion engine (10), the cylinder (D) being dedicated to EGR discharge, and which is connected to the exhaust gas discharge passage (34) communicating with the atmosphere; a second exhaust gas discharge port (30b) provided to the cylinder (D); an EGR passage (36) for connecting the second exhaust gas discharge port (30b) and the air intake passage(16); a first exhaust gas discharge valve EX1 (32a) and a second exhaust gas discharge valve EX2 (32b) which open and close the first exhaust gas discharge port (30a) and the second exhaust gas discharge port (30b); and a variable valve device (34) for exhaust gas, having valve stop mechanisms respectively provided for the first exhaust gas discharge valve EX1 (32a) and the second exhaust gas discharge valve EX2 (32b). |
