“…Among the liquid fuels, kerosene is identified to have slightly larger opening angles in many test points (figures 12 and 13). With respect to LFO, the observation is in line with the results by Yu et al (2016) who attribute the finding to increased turbulence in the injector nozzle. Increased turbulence, on the other hand, could be a result of decreased viscosity (Dernotte et al 2012).…”

“…The shorter penetration of propane sprays can be explained by lower initial momentum due to lower density as well as the loss of momentum during spray evolution as a result of droplet breakup and evaporation. According to Yu et al (2016), lower viscosity induces smaller droplets in the spray, and this can, together with different densities, explain some of the differences between the fuels. This viewpoint is supported by Dernotte et al (2012) who conclude that both viscosity and fuel density affect spray penetration and opening angles.…”

The present study investigates fuel spray penetration and opening angles for EN 590 light fuel oil, kerosene, hexane, methanol, and propane. Furthermore, droplet sizes are studied for methanol and light fuel oil sprays from a single location at the edge of the sprays. The fuels were injected from a marine-size common rail diesel injector to a spray chamber filled with nitrogen, and the results were based on the analysis of shadow images. The results indicated that propane sprays would penetrate slower and less than the sprays of the other fuels, but that the differences are decreased and finally almost disappeared when increasing chamber density. Apart from the lowest tested chamber density of 1.2 kg/m 3 , propane formed significantly narrower sprays than the other fuels. With the exception of propane, the fuels had mostly similar responses to increased chamber densities. Variations between repetitions were large in relation to the differences in average values between the liquid fuels. Concerning droplet size measurements, the results suggested that methanol sprays would be characterized by slightly smaller droplet sizes than LFO sprays in the tested conditions. This finding is in line with an earlier study, albeit the found differences were smaller.

“…49 This implied that under high-temperature vaporizing conditions, air entrainment of kerosene and diesel sprays were very similar. 81 From the kerosene spray experiments conducted by the authors’ group 43,91,92 under non-vaporizing and non-reacting conditions, kerosene was seen to give a shorter spray penetration as compared to diesel. This was attributed to the lower viscosity of kerosene which contributed to better spray breakup to form smaller droplets with lower momentum that resulted in a shorter penetration.…”

The use of kerosene in direct injection compression ignition engines is fundamentally due to the introduction of the Single Fuel Concept. As conventional direct injection compression ignition diesel engines are made specifically to use diesel fuel, the usage of kerosene will affect engine emissions and performance due to differences between the fuel properties of kerosene and diesel. As a result, in order for kerosene to be properly and efficiently used in diesel engines, it is needful for the scientific community to know the properties of kerosene, its autoignition and combustion characteristics, as well as its emissions formation behavior under diesel engine operating conditions. Moreover, it is desirable to know the progress made in the development of suitable kerosene surrogates for engine applications as it is a crucial step toward the development of reliable chemical reaction mechanisms for numerical simulations. Therefore, in this work, a comprehensive review is carried out systematically to better understand the characteristics and behavior of kerosene under direct injection compression ignition engine relevant conditions. In this review work, the fuel properties of kerosene are summarized and discussed. In addition, fundamental autoignition studies of kerosene in shock tube, rapid compression machine, fuel ignition tester, ignition quality tester, constant volume combustion chamber, and engine are compiled and evaluated. Furthermore, experimental studies of kerosene spray and combustion in constant volume combustion chambers are examined. Also, the experimental investigations of kerosene combustion and emissions in direct injection compression ignition engines are discussed. Moreover, the development of kerosene surrogates, their chemical reaction mechanisms, and the modeling of kerosene combustion in direct injection compression ignition engines are summarized and talked about. Finally, recommendations are also given to help researchers focus on the areas which are still severely lacking.
