Abstract

The autoignition characteristics of conventional jet fuels (category A) and alternative fuels with targeted properties (category C) were studied using a rapid compression machine and the direct test chamber charge preparation technique. Ignition delay measurements were performed to examine the effects of these unique fuels at low compressed temperatures (625 K ≤ Tc ≤ 735 K) a 20 bar compressed pressure and equivalence ratios of φ = 0.25 0.5 and 1.0 in synthetic dry air. Chemical makeup of the fuel shows insight into the effect of the amount of branching in isoalkanes and aromatic influences on autoignition. The results showed considerable variability in the ignition properties at these low temperature and lean conditions. This variability may affect combustion performance when the engine is running outside the normal operational map or for new engine architectures in the future.
