Successful operation of the Cooper-Bessemer JS-1 engine on coal–water slurry (CWS) fuel has been achieved at full power output, part load, and part speed conditions with varying degrees of diesel pilot fuel including zero pilot (auto-ignition of CWS). Selected results of the effect of pilot fuel quantity, pilot fuel timing, and manifold air temperature on engine performance are presented. Also, the influence of injector nozzle hole size and CWS mean particle size on engine performance is studied. High injection pressures resulted in good atomization of CWS and in combination with heated combustion air resulted in short ignition delays and very acceptable fuel consumption. Low CO/CO2 ratios in exhaust gas analysis confirmed good combustion efficiency. NOx emissions are compared for CWS and diesel fuel operation of the engine. Effect of injector nozzle hole size and manifold air temperature on NOx emissions is studied.
