As part of a DOE study to determine the effective utilization of alternate fuels in medium-speed diesel engines, a residual shale oil (RSO) was fired in an APE-Allen, 1000-rpm, 9.5-in. bore diesel engine. Various fuel injection modes were considered. Based on a fuel characterization study and go/no-go tests, it was determined that the direct firing of 100 percent RSO gave performance comparable with that using No. 2 diesel fuel; consequently, performance/endurance tests were performed using 100 percent RSO. Conclusions of this test program are: Laboratory tests showed low levels of corrosion and deposit-causing elements. Therefore, corrosion and wear of engine components, when using RSO, should be no worse than for standard diesel fuel. The high wax content of RSO requires heating for supply, handling, and injection systems. Laboratory tests showed that the cetane number of RSO was equivalent to No. 2 diesel; hence, no engine modifications should be needed to burn RSO. The engine performance on RSO was essentially similar to standard diesel fuel. The thermal efficiency was slightly lower and Bosch smoke and particulates were slightly higher, especially at low load. Soft carbon deposits, formed on injectors when using RSO, did not affect performance. The 115-hour endurance test showed no significant performance deterioration. The deposit accumulation in combustion chambers and ports was not severe but was greater than standard diesel fuel would produce. Longer endurance tests are required to fully establish this conclusion. 41 figures, 21 tables.
