Highlights • Fundamental characteristics of non-edible biodiesel are investigated. • Thermo-physical properties and evaporation characteristics are determined. • Cotton seed biodiesel, diesel and the blends of Cotton seed biodiesel with diesel are studied in engine scenario. • B25, a blend of 25% cotton seed biodiesel and 75% diesel by volume is found to be giving optimum performance.

Abstract An experimental study to measure the evaporation rates, engine performance and emission characteristics of cotton seed biodiesel (cotton seed oil methyl ester) and its blends in different volumetric proportions with diesel is presented. The thermo-physical properties of all the fuel blends have been measured and presented. Evaporation rates of neat cotton seed biodiesel, neat diesel and their bends have been measured under slow convective environment of air flowing with a constant temperature. Evaporation constants have been determined by using the droplet regression rate data. The neat fuels and fuel blends have been utilized in a test engine with different load conditions to evaluate the performance, combustion and emission characteristics of the fuels. The specific fuel consumption values of the two blends, viz. B25 and B75 are found to be same. At the highest load, B0 records the lowest CO volume followed by B100. From the observed evaporation, performance and emissions characteristics, it is suggested that a blend of B50 and B75 can be optimally used in standard diesel engine settings.
