Experiment A range of experiments have been performed including gaseous and particulate emissions analysis on a Auxiliary
Power Unit (APU) engine which has been installed at the Low Carbon Combustion Centre at The University of Sheffield.
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 1st 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.
