The authors investigated the injection and combustion characteristics of a methyl oleate (Methyl 9(Z)-octadecenoate C19H36O2; Mw 296.495), in blends with diesel No. 2 of 20-50% (wt./wt.) in order to evaluate the possibility of using it as an additive to full-bodied biodiesel for performance improvement. The FAME test fuel has been injected in an experimental single-cylinder separate combustion chamber engine with 77 mm bore, with a compression ratio of 23.5:1 at a pressure of 147 bars that proved capable of atomizing the higher viscosity fuel. The diesel fuel was blended with Methyl Oleate up to 50%, (O50) and the mixtures have shown favorable ignition characteristics, with the ignition delay of about 1.03 ms for petroleum diesel (D100) and slightly decreased for O50 at 2000 rpm with about 1% or 0.01 ms.
