• Ignition delays of cool flame (τ1) and of hot flame (τt) are experimentally measured for single n-decane, n-dodecane, n-tetradecane and n-hexadecane droplets, which have corresponding volatility to prevailing commercial hydrocarbon fuels, in hot air. Droplet diameter is 0.7 mm. Ambient pressure is 0.3 and 1.0 MPa. Ambient temperature is 550–1000 K. Results show the similarity of the examined fuels in terms of reactivity of the low- and high-temperature reactions. τ1 and τt are longer for the fuels with less volatility. τ2(=τt-τ1) is similar for the examined fuels. Ignition limits for cool flame and for hot flame are also similar, while they are slightly lower for the fuels with less volatility.
