Synfuel modified diesel. Quarterly progress report, July 1-September 30, 1981

Technical Report ·
OSTI ID:5267517

During the second quarter, Yanmar Diesel Co., Ltd. and Komatsu, Ltd. began baseline testing with standard diesel fuel No. 2 and various blends of SRC-II fuel oil. Yanmar obtained the operating range with their single cylinder prechamber engine on SRC-II. Komatsu obtained the operating range without spark assist on their 4D94 engine. Emissions data (except for particulates), combustion characteristics, startability, optimum injection timing, and cetane improver were obtained on the prechamber diesel engine. The particulate trap is now fabricated and particulate data should be forthcoming next quarter. The Komatsu 4D94 swirl engine will be installed with spark assist next quarter to determine the improvement of spark assisted combustion with SRC-II fuel. Thus far, higher inlet air temperature, high cooling water temperature, higher inlet pressure and fuel blending appear most conducive to successful operation with SRC-II fuel. 100% SRC-II fuel will not operate in the prechamber, swirl chamber, or direct injection diesel in the size tested.
