Fuels Tested Measurement Instruments (Mobile Emissions Laboratory) Engine Operating Conditions Smoke & particulate emissions produced by Jet A-1 and FSJF are similar to each other. Due to the absence of aromatics, the SPK result is substantially lower. FSJF is observed to produce substantially higher particulate mass as compared to Jet A-1 and SPK at the 1 st condition. UHC speciation allows further differentiation of emissions between engine conditions and between fuels. • The APU was ran at three conditions • Test condition lasted for six minutes after the APU was stabilised.
