Models for engine-map-wide prediction of diesel engine combustion and emissions

At the Aerothermochemistry and Combustion Systems Laboratory (LAV) at ETH Zurich, a new approach within the well-known trade-off in combustion process simulations between computational costs (and thus the capability for engine operating map calculations) on the one hand, and accuracy of predictions on the other, has been developed and applied successfully to diesel combustion, in particular to energy release and pollutant formation. Bio-inspired algorithms have been thereby used to identify values of critical model parameters.
