Gasoline compression ignition (GCI) engines have recently become a topic of interest due to its potential for very high thermal efficiencies with significant pollution reduction. High reactivity gasoline-like fuels with shorter ignition delay and similar volatility compared to market gasoline have been identified as a viable option for the GCI engines. To fully realize the potential of gasoline-like fuels in GCI engines, spray characterization of the fuel is needed for developing a better understanding of these fuels’ behavior in perspective of GCI engine applications. In this study, the spray characteristics of high reactivity gasoline-like fuel specially designed for GCI engines were investigated and compared with commercial gasoline fuel under non-reacting conditions. The new GCI fuel of RON 77 and E10 market gasoline of RON 91 were tested using a high-pressure custom-made multi-hole injector. The rate of injection, liquid and vapor penetration lengths were measured for both the fuels. It was found that the spray characteristics of GCI fuel are similar to that of the commercial E10 gasoline under non-reacting conditions.
