Empa and partners exploring DME as fuel with new heavy-duty test engine

Green Car Congress

Over the past few months, we have converted it to DME together with our partner FPT. In addition, the valves and valve seat inserts were converted to materials suitable for DME. An electrically driven compressor for precise exhaust gas recirculation is also used. This is done via exhaust gas recirculation (EGR).
