The device has a bypass duct (2) connecting an exhaust duct (3) to an intake duct (4) of an engine (1) to partly recycle exhaust gas towards engine`s inlet. The duct (2) has a valve (5) to control the recycled exhaust gas flow. The duct (2) has a dampening chamber (6) in upstream of the valve in the exhaust gas circulation direction, where volume of the chamber is determined to dampen pressure amplitude of gas created in the duct (2). |
