This is the final report of a program to investigate the autoignition behavior and chemistry of JP-8 components and blends in a singlecylinder, variable compression ratio research engine. The program objectives were to determine the branching pathways of JP-8 components at autoignition conditions establish the impact of recycle fraction on chemistry, and aid in the development of chemical models. The program has made progress toward making the measurements that will resolve these issues. The study has mapped the reactivity of components in present and future JP-8 type fuels as a basis for beginning the studies of gas sampling from the exhaust and in-cylinder which will aid in identifying reaction pathways. The work has also proposed a new way to compare the reactivity of hydrocarbons. However, the initial updating of the facility and the required relocation, occurring during the third year, took more time than expected and consequently, we were unable to fully achieve the program objectives. The PI s are committed to continuing the work with in-house funding promised as compensation for the lost time during the relocation. Results of this ongoing work will acknowledge the support of ARO and resulting dissertations and manuscripts will be submitted to the ARO archives.
