A Study of Alternative Approaches to Produce Obscuring Smoke with JP-8 in Vehicle Engine Exhaust Smoke Systems (VEESS)
Abstract
Studies were conducted to evaluate several approaches to form obscuring smoke from diesel-powered armored equipment using JP-8 fuel in the VEESS system. One approach investigated the idea of removing the more volatile fractions from the fuel using a vehicular-installed fractional distillation unit, thus providing a less volatile portion to be used as the smoke agent. Results of this study did indicate the possibility of using the less volatile 20 percent bottoms portion of the base fuel. A second approach was investigated that used blends of JP-8 fuel and 5 percent crankcase lubricant in either the combustion chamber and/or the air induction system. It was thought that this combination of fuel/lubricant would produce a soot-laden exhaust that would provide nucleation sites for fuel vapor condensation. These results were not successful for the fuel/engine system that was evaluated. Keywords: Smoke generators; Persistency; Obscuration; VEESS; Fractional distillation.
