Numerical Investigation of the Ignition Delay Time of Kerosene Premixed Combustion in an SI Engine

Abstract: SI engines are installed widely in small aircrafts as they have good fuel economy. Currently, these SI engines are fueled with gasoline, although their safety can be improved if kerosene is used. However, the combustion performance of kerosene cannot fulfil the requirements due to the differences in physicochemical properties. This study investigates the ignition delay time of kerosene at a pressure range of 15–35 bar and a temperature range of 600–1000 K. A detailed chemical reaction mechanism is employed for… Show more

“…Table 2 lists the main elementary reactions for the premixed combustion of kerosene and hydrogen. Compared with pure kerosene shown in [42], reactions R5 (KERO-OO = KERO#OOH), R6 (KERO#OOH + O 2 = OOKERO#OOH), R4 (KERO-+ O 2 = KERO-OO), and R72 (H 2 O 2 + OH = HO 2 + H 2 O) are removed, while the importance of R78, R32, and R67 rises. R6 and R4 are two oxygenation reactions, and R5 is the isomerization of the product of R4.…”
