The stringent global emission regulation requires significant efforts to enhance efficient combustion while satisfying the quality of exhaust emissions demand. This present work investigates the emission and combustion characteristics of African Pear (Dyacrodes edulis) Seed Oil Methyl Esters in different blends (25%, 50%, 75% and 100%) when compared with diesel fuel. The blends with petrodiesel were run on Perkins 4:108 CI diesel engine and the CO and NOX emissions were measured using Bacharach PCA2 235 – Q51007 emission gas analyzer at varying loads of 5 Nm, 10 Nm, 30 Nm and 40 Nm and constant speed of 1500 rpm. The NOx emission was comparatively higher than that of petrodiesel while CO emission was very close to that of petrodiesel. The overall result shows that the combustion of blends of methyl esters from Dyacrodes edulis seed oil with diesel in CI engine is showed close emission toxicity with petrodiesel.
