Arrangement with a protected turbocharger in the exhaust gas recirculation line

摘要

The treatment system for exhaust gases from the internal combustion engine (2) of given cubic capacity (3), includes an exhaust gas recycle line (4) in which the return flow of exhaust gases is compressed by a turbocharger (5). In this line (4), ahead of the turbocharger, a sieve layer (6) is provided. This is greater in cross section than the mean cross section of the exhaust gas recycle line (4). The available area of the sieve layer (6), is at least 10 square centimeters per liter of cubic engine capacity.
