SRC II in Spark Assisted Multifuel Diesel Engine

Solvent Refined Coal (SRC II) was evaluated for its acceptability as alternate fuel for a spark assisted multifuel diesel engine which was modified to accept a spark plug in the swirl chamber. The objective of this study was to determine the effect of the use of SRC II on performance and emissions of the spark assisted swirl chamber diesel engine in comparison with diesel fuel operation.

The results showed that SRC II could be used on the spark assisted diesel engine with engine performance comparable to that with conventional diesel fuel when the engine operating condition was optimum. However at other engine operating conditions large increase of unburned hydrocarbon and particulate emissions was found when operated with SRC II.
