Zusammenfassung The prediction of pollutant emissions generated by IC engines has been a challenge since the introduction of the emission regulation legislation. This paper describes the approach followed by the authors to strictly couple two different 1D modeling tools in a co-simulation environment, to achieve a reliable calculation of engine-out and tailpipe emissions. The main idea is to allow an accurate 1D simulation of the unsteady flows and wave action inside the intake and exhaust systems, without resorting to over-simplified geometrical discretization, and to rely on advanced combustion models and kinetic sub-models for the calculation of cylinder-out emissions.
