heptane and n-butanol binary fuel. The O2 concentration in the mixture was set to 9-10% to
make high exhaust gas recirculation (EGR) rate condition which leads low NOx and soot
emission. Experiments were performed using a rapid compression machine (RCM) at
compressed pressure 20bar, several compressed temperature and three equivalence ratios
(0.4, 1.0, 1.5). In addition, a numerical study on the ignition delay time was performed using …
