摘要： The invention relates to an internal combustion engine (1). The internal combustion engine comprises at least two cylinders (2). Each of the two cylinders comprises a combustion chamber (3) and has an inlet for a fuel and an outlet (5) for an exhaust gas with an outlet valve (6). The engine comprises at least one separation device (7) downstream of the combustion chambers (3) for separating the exhaust gas of all combustion chambers (3) into a first and a second exhaust gas stream. A first (8) and a second exhaust line (9) are connected to the at least one separation device (7). The at least one separation device (7) is configured to separate the exhaust gas from the combustion chambers (3) into a first gas stream for the first component exhaust line (8) and a second gas stream for the second component exhaust line (9). A first selective catalytic reduction (SCR) reactor (10) is arranged in the first component exhaust line (8) downstream of the separation device (7). The second component exhaust line (9) and the first component exhaust line (9) are separate from each other at least until the first SCR reactor (10). The first SCR reactor (10) has a maximum capacity of 80% or less of a full load outflow rate of the at least two cylinders (2).
