Quantifying the contribution of lubrication oil carbon to particulate emissions from a diesel engine 2003-01-1987
The contribution of lubrication oil to particulate matter (PM) emissions from a Cummins B5.9 Diesel engine was measured using accelerator mass spectrometry to trace carbon isotope concentrations. The engine operated at fixed medium load (285 N-m (210 ft.lbs.) at 1600 rpm) used 100% biodiesel fuel (B100) with a contemporary carbon-14 (14C) concentration of 103 amol 14C/mg C. The 14C concentration of the exhaust CO2 and PM were 102 and 99 amol 14C/mg C, respectively. The decrease in 14C content in the CO2 and PM are due to the consumption of lubrication oil which is 14C-free. Approximately 4% of the carbon in PM came from lubrication oil under these operating conditions.
