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

Green Car Congress

With the most recent design, an increase of the efficiency level of around 1–2 percent-points can be expected. 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. Soltic et al.
