This paper describes experiments conducted using a single cylinder, spark ignition research engine to examine the effect of the branched chain alkane isobutane (RON 102) on the autoignition chemistry of straight chain n-butane (RON 94). Isobutane was added in increasing quantities. Measurement of cylinder pressure and the analysis of end gas species were used as diagnostics to determine the knock point and ascertain the end gas reactivity. Examination of the chemical species in the end gas suggests that low temperature chemical reactions are occurring; and increasing the amounts of isobutane in the fuel mixture leads to higher yields of propene and chain terminating methyl radicals.
