文摘

Ignition delay times of ethane/dimethyl ether (DME) blends (DME blending ratios of 0, 20, 50, and 100%) were studied behind reflected shock waves at pressures of 2.0 and 20.0 atm, temperatures of 1100鈥?500 K, and equivalence ratios of 0.5, 1.0, and 2.0. Fuel mixtures were prepared with a constant argon dilution ratio for reasonable comparison. Two previous models including both ethane and DME chemistry were used to validate against the measured data. Subsequently, the chemical analysis was performed to obtain insight into the effect of the equivalence ratio and blending ratio on the ignition delay time.
