Measurements on the combustion characteristics or dimethyl ether(DME:CH₃OCH₃) as compared with LPG in constant volume combustion chamber have been conducted. The DME is a good alternative fuel having oxygen component in fuel. To elucidate the combustion characteristics of dimethyl ether as a fuel. the combustion pressures, combustion durations, and pollutants(NOx, CO₂, CO) are measured with equivalence ratios(ø), and initial pressures of fuel-air mixture, In the case or DME, the NOx concentration peaks in lean flame ø= O.85 ~0.9, and CO₂ concentration peaks at ø=1.1, while the CO concentration abruptly rises at the condition of fuel-rich mixtures. {{br}} |
