Abstract (en)
[origin: WO2017167561A1] The invention relates to a method for operating an internal combustion engine (1) through specification of an injection profile which is defined by adapted injection parameters (u* e,k ), having the following steps: – determining steady-state injection parameters (u e,k ) on the basis of a predefined steady-state injection profile characteristic map; – determining corrective injection parameters (Δu e,k ) on the basis of a predefined corrective injection parameter model, which provides corrective injection parameters (Δu e,k ) as a function of one or more state variables of an air supply system (3) and/or exhaust-gas discharge system (4) of the internal combustion engine (1); – applying the corrective injection parameters (Δu e,k ) to the steady-state injection parameters (u e,k ) in order to obtain the adapted injection parameters (u* e,k ).
