Abstract
This paper reports spark ignition behavior in simulated exhaust gas recirculation ambience using rapid compression machine. In this study, mixtures of nitrogen and oxygen without carbon dioxide are used as a simulated EGR gas. The fuel tested is propane. The equivalence ratio ranges from 0.5 to 0.62 and simulated EGR ratio ranges 20% to 50% at stoichiometry. Compression ratios are 9 and 10 initial pressure of premixed gas is 100kPa and 200kPa. The ignition probability is discussed in terms of the mole fraction of oxygen and nitrogen of ambient gas.
