Claim 20:
21. A system, comprising:
a controller configured to:
set a target value, for an emissions average value of an exhaust emissions portion of an exhaust gas produced by one or more piston-cylinder assemblies of an internal combustion engine, to achieve in relation to a period of time at a discharge from an exhaust gas aftertreatment apparatus having at least one catalytic converter; and
calculate an emissions reference value at least based on an already emitted amount of the exhaust emissions portion and the target value, wherein the emissions reference value is selected to achieve the target value by an end of the period of time;
wherein the controller is configured to, during a starting time of the internal combustion engine, reduce the exhaust emissions portion by at least setting a power ramp for the internal combustion engine in a first time portion, after a power output reaches a minimum power output, until the power output reaches a limit value with a first lesser gradient and in a second time portion until the power output reaches a nominal power output of the internal combustion engine with a second greater gradient, wherein the second greater gradient is calculated in dependence on a remaining time to reach the starting time.
