Analytical information supplemental to data is presented in this paper. Solid-sample injection gas chromatrography and X-ray fluorescence were employed to characterize the particulates collected on Pallflex and Fluoropore filters. The complete preweighed filter was thermally desorbed and separated by capillary GC with simultaneous flame ionization (FID), thermal conductivity (TCD), nitrogen/phosphorus (NPD), and flame photometric (FPD) detection. Results are reviewed in terms of: % non-volatiles, % volatiles (fuel and lube oil contributions correlated to various engine speeds and loads), as well as detectable nitrogen, phosphorus, or sulfur compounds. XRF data were obtained from the Fluoropore filters to determine the concentrations of typical additive metals Mg, Ca, P, and Zn present in the particulate that would be indicative of oil consumption mechanisms and any tendencies for additive-sourced materials to selectively be captured as particulate matter.
