摘要：

RP-3 jet fuel could be an alternative fuel for diesel engines. In this study, the injection characteristics of RP-3 jet fuel under single and split injection strategies were investigated and compared with diesel fuel. The experimental results indicate that RP-3 jet fuel has slightly shorter injection delay time than diesel fuel, but this difference is negligible in actual engine operations. Further, although the lower density and viscosity of RP-3 jet fuel lead to higher volumetric injection rates and cycle-based injection quantities, the cycle-based injection mass and the mass injection rates at the stable injection stage of RP-3 jet fuel are close to or slightly lower than those of diesel fuel. Based on these experimental observations, it could be concluded that fuel physical properties are the secondary factor influencing the injection characteristics in both single and split injection strategies, as RP-3 jet fuel and diesel fuel are taken for comparison.
