A 1978 Oldsmobile 5.7 l V-8 Diesel engine was operated on DF-2 and DF-M (shale oil), and a single-cylinder 0.3 l Avco-Bernard engine was operated of DF-2 and various vegetable oils. The objective of the V-8 study was to screen the DF-M fuel prior to beginning a more detailed single-cylinder engine study. The objective of the vegetable oil tests was to provide a detailed comparison of these oils and DF-2. In both cases, performance and emission data were obtained and biological activity of the soluble organic fraction of particulate samples was determined using the Ames Test. Results of the V-8 study show about equal performance and Ames Test activity for both fuels. With the vegetable oil tests, a slight increase in thermal efficienc was noted, but this was accompanied by slight increases in gas phase emissions and large increases in total aldehyde and particulate mass emissions. The Ames activity of the vegetable oils appears to be lower than that of the DF-2.
