Internal combustion engine, particularly for motor vehicle, comprises exhaust gas recirculation device with return line, by which exhaust gas from exhaust tract is returned through extraction point into inlet duct

摘要

The internal combustion engine (28) comprises an exhaust gas recirculation device (68) with a return line (70), by which the exhaust gas from an exhaust tract (71) is returned through an extraction point (72) into an inlet duct of the internal combustion engine through a discharge point (74). A pressure modulator (82) of the exhaust gas recirculation device is provided upstream the discharge point and downstream the extraction point in the return line.
