Abstract

A rapid compression machine (RCM) is used to study the autoignition characteristics of JP-8 and JP-5 blended in 50-50 mixtures by volume with their respective camelina-derived hydroprocessed renewable jet (HRJ) fuel at low temperature conditions. The tests employ the direct test chamber (DTC) charge preparation method which allows for high reproducibility of measurements. Ignition delay measurements are compared between the conventional military jet fuels, HRJ fuels, and the 50-50 blends. Measurements are made at compressed pressures of 5, 10, and 20 bar at an equivalence ratio of 1.0 and compressed temperatures between 625 K and 710 K. Additional ignition delay measurements are reported at reduced equivalence ratios of 0.5 and 0.25 at a compressed pressure of 20 bar and temperatures between 635 K and 720 K.
