Abstract
The purpose of this study is to investigate combustion and exhaust characteristics including nano-particles in compression ignition engines fueled with DME. Considered additives of the present study are bio-diesel, butanol, and MTBE. DME fuel was directly injected into the cylinder at 50㎫ injected pressure. 10% mass fractions of additives were blended with DME. Experiments were performed at 1200rpm engine speed and nano-particle was measured by SMPS (Scanning Mobility Particle Sizer) devices. Results of combustion characteristics is showed that considered additives have little effect on combustion pressure. However, patterns of heat release rate were dependent on properties of additives. Nano-particles of MTBE were the lowest among considered additives
