Abstract

An engine control system (28) causes combustion chambers (20) to be fueled during an engine cycle by a main injection (38) ending no later than substantially at the TDC between compression and expansion strokes of the cycle without any further injection of fuel during the expansion stroke, and then during the exhaust stroke of the cycle, by a post-injection (40) for elevating the temperature of the gases into a regeneration temperature range for regenerating a diesel particulate filter (36).
