A Phenomenological Mean Value Soot Model for Transient Engine Operation

A means of characterizing the raw soot emissions from modern common-rail diesel engines is required so that their control and the regeneration of an associated particulate filter can be optimized, though no suitable sensor currently exists. Thus, under the framework of a FVV research project, a fast soot model to calculate the raw soot emissions from a common-rail diesel engine operating under both steady state and transient operating conditions was developed and validated at the Aerothermochemistry and Combustion Systems Laboratory (LAV) at the ETH Zurich.
