An internal combustion engine with an open-loop or closed-loop control device (2), wherein at least one combustion chamber (3) of the internal combustion engine (1) is designed to burn a fuel-air mixture using at least one combustion parameters that can be influenced by the open-loop or closed-loop control device (2), wherein the open-loop or closed-loop control device (2) has an emission control loop that is configured to actuate the at least one actuator that influences the at least one combustion parameter as a substitute parameter for NOx emissions by means of a functional relationship in such way that at last one combustion parameter can be set for each target or actual power rating of the internal combustion engine (1), wherein the functional relationship takes account of an influence of a change of the exhaust backpressure (p3′) affecting at least one combustion chamber (3).
An internal combustion engine with an open-loop or closed-loop control device, wherein at least one combustion chamber of the internal combustion engine is designed to burn a fuel-air mixture using at least one combustion parameter that can be influenced by the open-loop or closed-loop control device, wherein the open-loop or closed-loop control device has an emission control loop that is configured to actuate the at least one actuator that influences the at least one combustion parameter as a substitute parameter for NOx emissions by a functional relationship in such way that the at last one combustion parameter can be set for each target or actual power rating of the internal combustion engine, wherein the functional relationship defines a charge pressure (p2′) based on a desired value for a power (Pmech), the NOx emissions and a given level of an exhaust backpressure (p3′) and is saved in the open-loop or closed-loop control device, wherein the functional relationship takes account of an influence of a change of the exhaust backpressure (p3′) affecting at least one combustion chamber.
A process for regulating or controlling an internal combustion engine, wherein in at least one combustion chamber of the internal combustion engine a fuel-air mixture with at least one combustion parameter that can be influenced is combusted, and wherein the at least one combustion parameter is open loop or closed loop controlled through at least one actuator that influences the at least one combustion parameter as a substitute parameter for NOx emissions as part of an emission control loop by a functional relationship in such way that at least one combustion parameter is set for each target or actual power rating of the internal combustion engine, wherein the functional relationship defines a charge pressure (p2′) based on a desired value for a power (Pmech), the NOx emissions and a given level of an exhaust backpressure (p3′), wherein by the functional relationship it is taken account of an influence of a change of the exhaust backpressure (p3′) acting on at least one combustion chamber.
