Performance and Emissions of a DME Diesel Engine - a Simulation Study
Paper i proceeding, 2006

In order to investigate DME combustion in a heavy duty diesel engine, a three dimensional CFD study was performed. Following parameters were investigated; injection timing, injected fuel mass, umbrella angle and EGR amount with respect to combustion attributes and emissions formation. It can be concluded that a large amount of EGR effectively suppresses NO formation and that the low heating value of DME can be balanced by a larger amount of injected fuel without any penalties in combustion efficiency and CO emissions.
