Abstract:
1. A method for operating auto ignition combustion engines, comprising: directly linking outputs to an injected fuel mass flow distribution and to an injection timing by taking into account engine out emissions and/or drivability constraints by using an optimization method, determining an optimized torque realization TQI_SP by minimizing an error of a multi-objective function for overall engine operating points, wherein the determined optimized torque realization is implemented by at least one engine actuator configured to control at least one of: a number of injection Nb quantities injected per elementary injection MF a start of injection SOI an air path control by the way of the global equivalence ratio Φ because in our case the measured air mass flow, MA, is linked to injected mass flow MF by Φ=(MF/MA)*α a global equivalence ratio Φ is set according to the engine load targets and the turbocharger air mass flow limitation for a given operating point; and an EGR rate, X
