Internal combustion engine having an exhaust gas turbocharger and an exhaust gas recirculation system

摘要

In a supercharged internal combustion engine having an intake duct and an exhaust gas recirculation system and comprising an exhaust gas turbine with two separate flow passages of different flow cross-sections arranged upstream of a turbine rotor of the exhaust gas turbine, each flow passage being in communication with a respective engine exhaust line for supplying it with exhaust gas and an exhaust gas recirculation line extending from one of the engine exhaust lines to the engine intake duct, a bypass line bypassing the exhaust gas turbine is provided and a common control element is arranged in the recirculation line of the exhaust gas recirculation system and in the bypass line for controlling the exhaust gas flow from the recirculation line selectively to none or any of the intake duct and the turbine bypass line.
