A two-stroke internal combustion engine with a SCR reactor located downstream of the exhaust gas receiver

摘要

A two-stroke internal combustion engine (1) has a SCR reactor (11) located downstream of an exhaust gas receiver (6). A regeneration flow path (17) is connectable to the SCR reactor for regenerating catalyst material in the SCR reactor. At least one cylinder out of the plurality of engine cylinders is adapted to deliver to the regeneration flow path (17) a first flow of exhaust gas at a higher temperature than the temperature of the exhaust gas in the exhaust gas receiver (6).
