Cummins Engine Company of Columbus, Indiana, has proposed a two-year program to test three diesel engines operating on coal-derived liquid fuels and compare the results with standard diesel fuel oil No. 2; namely: (1) prechamber diesel; (2) dual fuel diesel (direct injection); and (3) spark-assisted diesel engines. The proposed diesel combustion chambers to be investigated are shown in Figure 1. The three types of diesel engines to be tested were to be modified in three forms; namely: (1) conventional water-cooled; (2) waterless-uncooled; and (3) adiabatic (uncooled). Because of limited funds, the first year's work covered only the conventional water-cooled prechamber diesel engine and the spark assisted prechamber diesel engine. Subcontracts have been let to test the prechamber diesel engine by Yanmar Diesel Co., and the spark-assisted prechamber by Komatsu, Ltd. Cummins will monitor the program. The direct injection dual fuel engine test which was asssigned to Cummins will be delayed until the second year of the contract. No engine modifications for waterless-uncooled and adiabatic uncooled are scheduled for the first year. The selected engine models were installed in the laboratory. Preliminary operation was made by Yanmar. Both subcontractors began to construct a particulate measuring system according to Cummins' recommendation.
