This work explores the role of the ignition quality of a fumigated fuel (DME andpropane) on combustion phasing and brake thermal efficiency (BTE), which wasinvestigated in a 2.5L turbocharged common rail light-duty diesel engine.Different combinations of DME and propane were fumigated into the intake airand displaced some of the directly injected ultra-low sulfur diesel fuel (ULSD)needed to maintain the engine at a constant speed and load.
