Abstract
In this article, the detailed mechanism of isopentanol was simplified by direct relationship graph error propagation (DRGEP), generation rate analysis, reaction path optimization, and sensitivity analysis, and a comprehensive simplified mechanism of isopentanol/gasoline alternative fuels was obtained. Isopentanol/gasoline-characterized fuels with different blending ratios were investigated, and the results showed that blending of isopentanol promoted the autoignition of gasoline. It was found that blending isopentanol does not significantly affect the low-temperature reaction path of alkanes, but increases the reaction path flux from toluene to benzene. During combustion of isopentanol/gasoline alternative fuels, the isopentanol component exhibits a unique two-stage combustion phenomenon.
