Abstract
In a method for determining an optimized fuel injection profile in an internal combustion engine, a setpoint combustion profile is firstly defined. Furthermore, at least one influential parameter which influences the setpoint combustion profile is determined. With the influential parameter, a corrected fuel injection profile is determined in a closed-loop control process. This method is preferably repeated iteratively.
Claims10
A method for determining an optimized fuel injection profile (EMK) of fuel in an internal combustion engine, comprising the steps of:
- determining firstly a setpoint combustion profile determining at least one influential parameter (a, pMax, pmi, SOC) which influences the setpoint combustion profile with the influential parameter (a, pMax, pmi, SOC), determining a corrected fuel injection profile (EMKkor-α, EMKkor-pMax, EMKtotal, Zvkor) in a closed-loop control process, repeating iteratively the preceding steps.
