Abstract

[Problem] Provided is an exhaust gas recirculation device and an engine with which outside air and recirculated exhaust gas can be effectively mixed. [Solution] An exhaust gas recirculation device 3 includes a mixing portion 31 that is connected to the front of an intake manifold 22 of an engine 2 and sends a mixture of outside air and the recirculated exhaust gas from a mixture outlet 311 to an intake manifold 22 side, an exhaust gas recirculation pipe 27 that guides the recirculated exhaust gas to the mixing portion 31, and an intake pipe 21 that guides the outside air to the mixing portion 31, the intake pipe 21 includes a first intake pipe 215 that is disposed inside the mixing portion 31 and has a discharge port 217 for discharging the outside air into the mixing portion 31, and a second intake pipe 216 that is disposed outside the mixing portion 31 and connected to the intake side of the first intake pipe 215, the first intake pipe 215 is formed so as to project toward the inside of the mixing portion 31, and the discharge port 217 is formed such that the opening thereof faces a different direction inside the mixing portion 31 from a direction extending from the first intake pipe 215 toward the mixture outlet 311.
