Abstract

An arrangement for exhaust gas feedback (1) in a turbocharged combustion engine with an exhaust manifold (2), while a transfer line (5, 5', 15) for EGR gases is arranged between the exhaust manifold and the inlet side of the engine and has inserted in it check valve devices (8, 8') allowing flow from the exhaust manifold. Distinguishing features of the arrangement are: that the arrangement is arranged to be inserted in a divided exhaust manifold incorporating two separate turbine inlet ducts (2, 2') each forming part of its exhaust manifold section; that the transfer line incorporates an EGR draw-off duct (5, 5') running from each turbine inlet duct to an EGR chamber (7); that the check valve device comprises two check valves (8, 8') each inserted in its inlet of an EGR draw-off duct in the EGR chamber, while the pressure in the exhaust manifold (2, 2') during the occurrence of momentary exhaust pulses is arranged to be utilised for EGR feedback.
