Autoignition of n-Butane/lsobutane Blends in a Knock Research Engine

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