Summary:

For better understanding of the in-cylinder combustion characteristics of DME, combustion radicals of a direct injection DME-Fueled compression ignition engine were observed using a spectroscopic method. In this initial report, the emission intensity of OH, CH, CHO, C2 and NO radicals was measured using a photomultiplier. These radicals could be measured with wavelength resolution (half-width) of about 3.3 nm. OH and CHO radicals appeared first, and then CH radical emission was detected. After that, the combustion radicals were observed using a high-speed image intensified video camera. C2 and CH radicals were able to observe roughly as images. However, the emission intensity of DME combustion was not strong enough to take OH, CHO and NO radical images. CH radical combustion occurred near the chamber wall and burned like a ring, as combustion progress, indicating active heat release occurred near the chamber wall
