Optimized heavy-duty CI engine fueled with DME delivers diesel performance, significantly reduces engine-out emissions

Green Car Congress

The experimental results showed that DME operation retains the performance on the base diesel engine (338 kW peak power) while significantly reducing the engine-out emissions. Transient operation is unproblematic and very low emissions can be achieved using the same exhaust gas treatment system as for diesel. Soltic et al.
