Abstract

Combustion, performance and emissions were studied for a DI diesel engine fuelled with DMM/diesel blends with DMM content from 0 to 50%. Results showed that, without changing the fuel supply system and the combustion system of a diesel engine, when using blended fuel with increased DMM percentage, BSFC is increased because the heating value of DMM is lower than that of diesel, while thermal efficiency increases a little. Smoke and CO emissions decrease while NO_x emission remains almost unchanged but HC emission increases. Peak pressure and pressure rise are slightly increased, and ignition delay is increased which results in more and faster premixed combustion. Fast diffusion combustion is due to the oxygenated fuel. The diesel engine fuelled with blend with 30% DMM fraction can get the satisfactory fuel economy and emission level.
