Chemical Kinetics Study About the Effect of NO₂ Addition on Low Temperature Oxidation and Ignition Delay (Second Report)

Abstract

Controlling the knocking is essential for achieving high compression ratio and high thermal efficiency of internal combustion engines. Previous studies have shown that NO/NO2 present in EGR affects autoignition. However, the mechanism has not been fully understood. In this study, kinetics and role of elementary reactions of NO and NO2 and fuel-derived intermediate products were investigated.
