Abstract

The invention relates to a large turbocharged two stroke diesel engine (1) of the crosshead type that is provided with an exhaust gas recirculation system (30,32) that can be activated or deactivated or can be operated with variable exhaust gas recirculation rates. In order to ensure proper matching of the turbocharger (16) , and in particular the compressor (18) of the turbocharger (16) in all operating conditions, a cylinder bypass flow path (40) that includes a controllable valve (42) enables matching the turbocharger 16 to the engine (1) in operation modes with or without exhaust gas recirculation.
