Synfuel modified diesel. Final report, March 31, 1981-May 25, 1982. [Including prechamber and spark-assisted, also hot adiabatic direct injection]
The Synfuel Modified Diesel program has yielded several interesting conclusions. The contemporary diesel engine, whether prechamber or direct injection, cannot burn SRC-II fuel without modification. When SRC-II is blended with a 50% or larger amount of standard No. 2 diesel fuel, the prechamber diesel can burn the blend with slight modification to the injection timing. The spark-assisted diesel has shown remarkable improvement in diesel combustion. It can handle blends as well as straight SRC-II during operation. The hot adiabatic direct injection engine has also demonstrated capability in burning SRC-II fuel. However, with the spark-assisted prechamber, or with the adiabatic direct injection engine, cold start is still a problem. Intake manifold heating is suggested for starting. The emissions characteristics measured with SRC-II fuel in the adiabatic diesel and conventional engine were similar. Mutagenicity is lower with SRC-II. The engine performance is quite similar to conventional diesel fuel when corrected for the lower heating value of the SRC-II fuel oil. This report covers the prechamber and the spark-assisted pre-chamber diesel engine by Yanmar Diesel Engine Co. Ltd and Komatsu Ltd respectively. Complementary performance and emissions data with SRC-II and No. 2 diesel fuel in an adiabatic direct injection engine is included in a report due in June 1983.
