Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an internal combustion engine including an exhaust gas recirculation device.SOLUTION: An internal combustion engine 10 including an exhaust gas recirculation device 50, includes a return valve 55 for determining an amount of exhaust gas to be recirculated to fresh air lanes 40, 41, and a control device for controlling the return valve on the basis of a combustion cycle. The control device opens and closes the return valve on the basis of angles of a crank shaft and/or a cam shaft by an angle measurement device. Opening of the return valve is adjusted on the basis of a pressure in an exhaust gas lane by a pressure sensor 24. The return valve can be driven through an electromagnetic actuator or a piezo-electric driving device, or by air pressure.SELECTED DRAWING: Figure 1 【課題】排気ガス再循環装置を備えた内燃機関を提供する。【解決手段】排気ガス再循環装置５０を備えた内燃機関１０は、新鮮空気レーン４０、４１に再循環すべき排気ガスの量を決定するための戻し弁５５と、この戻し弁を燃焼サイクルに依存して制御する制御装置とを備える。制御装置は、角度測定装置によるクランク軸および／またはカム軸の角度に依存して、戻し弁を開閉する。圧力センサ２４による排気ガスレーン内の圧力に依存して、戻し弁の開放が調節される。戻し弁は、電磁アクチュエータまたは圧電式駆動装置を介して、あるいは空気圧で駆動可能である。【選択図】図１
