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 (8100) with a contemporary carbon-14 ({sup 14}C) concentration of 103 amol {sup 14}C mg C. The {sup 14}C concentration of the exhaust CO{sub 2} and PM were 102 and 99 amol {sup 14}C/mg C, respectively. The decrease in {sup 14}C content in the CO, and PM are due to the consumption of lubrication oil which is {sup 14}C-free. Approximately 4% of the carbon in PM came from lubrication oil under these operating conditions.
