About half the oil consumed in the United State must be imported. From an economic and national security viewpoint, it is desirable to replace petroleum usage with domestically available energy sources such as coal. Slow and medium speed compression ignition engines are devices with the potential for conversion to coal fueling. Severe injection, safety, and handling problems arise with coal dust. Consequently, recent work focusses on coal slurried in a liquid carrier. Engine studies on coal slurry to date have investigated the slurries' wear, thermal efficiency, and injection performance. Previously lacking information on the compression ignition characteristics of coal slurries, specifically, the ignition delay times and conditions for ignition of 45 mass % coal in methanol, oil, and water are compared to methanol and diesel No. 2. 51 refs., 63 figs., 9 tabs.
