Vehicle Tests for Lsado

Event: International Seminar on Application of Powertrain and Fuel Technologies to Meet Emissions Standards
During 1995/1996 vehicle tests were conducted at the Esso Research Center, Abingdon (ERCA), to assess the effect of Low Sulphur Automotive Diesel Oil (LSADO = 0.05% mass sulphur) on some types of fuel injection pumps. Performance criteria included regulated emissions, black smoke emissions, fuel delivery (assessed on a test rig), pump component weight loss, and rating of the pump components to a procedure defined by the fuel injection pump manufacturer.
Low sulphur base fuels were run with and without lubricity additives, and performance criteria were checked periodically throughout the test duration of 100,000 km. The test concluded successfully with a better understanding of how bench lubricity tests correlate with field tests, and confidence that additive strategies can be employed to restore fuel lubricity performance back to the levels of 0.2% sulphur fuels.
