ABSTRACTIndicated specific energy consumption and exhaust emissions were measured for three coal-derived liquids in a direct injection, stratified-charge (PROCO) engine. The three fuels were obtained from different coal refining processes. One of the fuels met current gasoline specifications while the other two had volatilities somewhat below the specification and were more typical of some current gasoline blending components.A comparison of test results from these fuels was made with Indolene Clear, a petroleum-derived reference fuel. Little difference in indicated specific energy consumption or NOX emissions was observed between the coal liquids and Indolene Clear. The two fuels which had low front end volatility showed higher hydrocarbon and CO emissions at low speeds and loads than the reference fuel but performed well overall.On the basis of the tests, all three fuels appear to be potentially satisfactory in a direct-injection, stratified-charge engine. No characteristics attributable to their coal origin caused any significant problems in operation in such an engine.
