Utilization of SRC-2 fuel in an insulated diesel engine. Final technical report

The primary purpose of this project was to determine the capability of the uncooled and adiabatic engines, with their high in-cylinder temperatures, to burn poor quality low cetane fuels. Three NH cylinder engine configurations: a conventional cooled, an uncooled, and an adiabatic were assembled and tested for performance and emissions. No. 2 diesel baseline, shale, and coal derived fuels were burned in each of the above engine configurations. Engine fuel sensitivity to poor quality low cetane fuels was significantly reduced or eliminated by the uncooled and adiabatic engines. The low cetane number EDS and SRC-II fuels gave a combustion quality (ignition timing and noise levels) equivalent to No. 2 diesel fuel when burned in the adiabatic engine at optimum intake air temperatures and air fuel ratios for emissions and performance. 16 references, 67 figures, 18 tables.
