This work investigated the combustion characteristics of decanoic acid derived alkyl esters in an ASTM standard Fuel Ignition Tester (FIT), with special emphasis on the influence of carbon number variation for the alkyl moiety within the alkoxy group on the autoignition delay times. The compounds of interest include Me, Et, Pr, and Bu decanoate. Higher carbon numbers lead to an increase in reactivity in terms of the decreased ignition delay times for Me through Pr decanoate. However, there was a small reduction in relative reactivity for Bu decanoate. With increasing air temperature, while the ignition delay times showed a monotonic reduction for all the four fuels, the maximum rate of pressure rise exhibited a non-linear variation. Specifically, the maximum rate of pressure rise was found to increase at of 700-758 K and then decrease within 758-825 K. The post-combustion peak pressures also exhibited a similar trend. This reduction in reactivity with increasing temperature correlates to the neg. temperature coefficient behavior. In addition, all the test fuels show a two-stage ignition response at the lowest oxidizer temperatures investigated. Therefore, the current experiments demonstrate the suitability of the FIT as a research tool that can be used to extract information on fuel reactivity other than the widely studied metric of the derived cetane number
