“…Overall, K60P40 showed the highest ITE among all the test fuels, which can be attributed to its longer combustion duration and higher heat release rate. These findings are similar to the results of Bayindir, who reported that engine efficiency increased with the kerosene addition …”

The resurgence of aviation heavy fuel engines (HFEs) and the single fuel concept policy make it important to investigate the application of kerosene in aviation compression ignition engines. From the experience of automotive engines, biofuels, in particular higher alcohols, may offer better combustion and emission characteristics for HFEs. In this study, the combustion performance was analyzed in a commercial aircraft compression ignition engine burning diesel as a baseline fuel and Chinese aviation kerosene fuel (RP-3) blended with pentanol (so-called second generation biofuel) with different blending ratios. The injection timing as the most critical operational parameter was swept from 17 to 23°CA BTDC (crank angle before top dead center) under constant engine speed (1600 rpm) and fixed injection pressure (60 MPa). The indicated thermal efficiency of kerosene−pentanol blend (K60P40) was higher than those of all other test fuels, and the advancement in injection timing caused an increase in combustion temperature which improved both the indicated thermal efficiency and combustion efficiency. The combustion duration was shorter for kerosene−pentanol blends (K60P40 and K80P20) than diesel; however, the combustion duration considerably increased with advancing injection timings for all the test fuels. Kerosene and its pentanol blends showed longer ignition delay compared to baseline diesel due to their lower cetane numbers. The indicated specific fuel consumption (ISFC) values of K80P20 and K60P40 were demonstrated to be lower than that of baseline diesel. This work demonstrated the great potential of kerosene−pentanol fuel blends in aircraft diesel engines without significant modifications.

“…The primary reason might be that the combustion efficiency of kerosene is higher than that of diesel due to its shorter combustion duration and resultant higher isovolumetric degree. Similar experimental results were reported that engine thermal efficiency increased with the kerosene addition [44]. Furthermore, the K80P20 presented lower ITE and higher ISFC than kerosene by 1%-6.5%, which was due to less complete combustion of K80P20 caused by its lower combustion efficiency.…”

“…The higher oxygen content of COME shows negative effects on the formation of smoke and particulate matter (PM) emissions, while the higher density and viscosity show opposite effects. As a result, for COME-diesel blends, the smoke and PM emissions are just slightly decreased when small amount of COME is added under the low-and middle-engine loads Bayindir 2010a, 2010b;Bayindir 2010;Hoda 2010).…”

“…Cottonseed oil produced ETHYLENE GLYCOL MONOMETHYL ETHER COTTONSEED OIL MONOESTER 377 from cotton plants is one of the main vegetable oils supplied for food and other chemicals in China and other areas in the world. The formation, engine performance, as well as emission characteristics of biodiesels derived from cottonseed oil (mainly the cottonseed oil methyl ester (COME)) were widely investigated in most countries such as Brazil (Simoni, Mario, and Tatiana 2007), China (Yao, Ji, and Sun 2010), India (Syed, Raja, and Gopal 2009), Turkey Bayindir 2010a, 2010b;Bayindir 2010;Hoda 2010), the USA (Umer, Farooq, and Gerhard 2009), and so on. Previous studies indicated that, compared to diesel fuel, COME has lower UHC, CO, and SO x emissions, but higher NO x emission.…”

In this paper, a novel biodiesel, ethylene glycol monomethyl ether cottonseed oil monoester (EGMECOM), which was synthesized through transesterification reaction of the refined cottonseed oil with ethylene glycol monomethyl ether, was developed. Its chemical structure was characterized through FT-IR, 1 H NMR, and GPC analyses. Its main physical and chemical properties were tested. Also, with a two-cylinder DI diesel engine, its combustion performances and emissions characteristics were investigated. The results indicated that EGMECOM has a comparative high cetane number and a high oxygen content, which are the prime factors that determine its NO x and smoke emissions, respectively. As a result, the trade-off relationship between the NO x and smoke emissions is broken for EGMECOM fuel, which both reduce with the increase of EGMECOM fraction in the EGMECOM-diesel blends. As well, the high oxygen content shows positive effects on the reduction of both the CO and HC emissions. Compared to diesel fuel, a maximal reduction of the smoke, NO x , CO, and HC by 50.0%, 50.0%, 20%, and 55.6%, respectively, can be reached when EGMECOM is used. Besides, for EGMECOM, the combustion timing of engine is advanced, ignition delay is shortened, and the combustion is improved.
