<p>An arrangement for exhaust gas feedback in a combustion engine (1) with an ordinary first exhaust manifold (4), while a transfer line (8) is arranged between the engine's exhaust side and its inlet side. The invention is distinguished by the fact that the transfer line (8) starts from a separate second exhaust manifold (3) for EGR gases which is arranged on the exhaust side of the engine and which is connected to at least certain cylinders, while from each of said cylinders an exhaust duct (2) runs to the second exhaust manifold, an EGR exhaust valve (7) is situated in the orifice of the exhaust duct (2) in each of said cylinders, and the EGR exhaust valves (7) are arranged to be controlled so that the pressure in the delivering cylinders during their expansion stroke is used for EGR feedback. The invention also relates to a diesel engine incorporating the arrangement.</p> |
