PROBLEM TO BE SOLVED: To provide a device for extracting partial exhaust gas flow, an internal combustion engine including the device, in particular, a device for extracting the partial exhaust flow from an exhaust pipe of the internal combustion engine, and the internal combustion engine including an exhaust recirculation system.SOLUTION: A device for extracting partial exhaust flow from an exhaust pipe (105) of an internal combustion engine, includes a partial exhaust pipe (106) opened to the exhaust pipe (105), and an intake portion of the partial exhaust pipe is disposed in a state of substantially facing the exhaust gas flow, so that the partial exhaust flow can flow into the intake portion of the partial exhaust pipe (106) in utilizing a dynamic pressure of the exhaust flow. The device is disposed just near flow control members (101, 104) of the internal combustion engine. A valve is disposed in the partial exhaust pipe (106) to optimize the extraction of the partial exhaust flow. |
