| Abstract(E) | Oxymethylene dimethyl ether (OME) exhibits distinct fuel characteristics compared to conventional diesel, including significantly reduced soot emissions and late combustion, but it also has a lower heating value and tends to increase heat losses. Consequently, it is necessary to investigate combustion systems specifically optimized for OME. This paper presents a novel OME combustion concept combining a large nozzle diameter, low injection pressure, and a high compression ratio. The performance of this concept was evaluated through experimental investigations on a single-cylinder engine, complemented by in-cylinder combustion visualization. |
