GL Measurements Ultra-Large Bore Engine • Exhaust gas and fuel samples have been analysed in the laboratory of GL prior to onboard measurements to find out the particulate matter composition and the influence of fuel quality on emissions. • Emissions measurements at required operating points specified by IMO for Test Cycle E3 have been conducted. Test Cycle E3 power 100 % 75 % 50 % 25 % speed 100 % 91 % 80 % 63 % Athens, October 8, 2003 Final Presentation
