Abstract: Presently, the world is grieving with lack of energy sources, since the petroleum reserve are being depleted very soon, moreover the world’s temperature is rapidly increasing resulting from the emissions of automobile. More consideration should be given to this issue so, the researchers across the globe making difficult trials to find the best substitute energy reserve which swaps the fossil diesel petroleum. This article deals with manilkara zapota methyl ester, the biodiesel taken from a non-edible feed stock Manilkara Zapota seed generally known as Sapodilla. It has exceptional fuel properties like fossil diesel. By the transesterification process, Manilkara Zapota Methyl Ester (MZME) was taken out from crude manilkara zapota seed oil. Numerous test samples were equipped in the combination ratios ranging from 10% to 30% and the mixtures were selected as ZB10D90 (10% MZME + 90% Pure Diesel), ZB20D80 (20% MZME + 80% Pure Diesel) and ZB30D70 (30% MZME + 70% Pure Diesel). An experimental examination was performed on a single cylinder four stroke direct injection diesel engine to find out the emission, combustion properties, and performance at continuous speed and numerous load circumstances. The experimental outcomes were exposed that, at complete load condition, the performance aspects like BSFC and BTE were improved by 7.69% and 7.44% respectively, and the parameters of emission like CO was reduced greatly by 64% whereas NOx , HC and smoke opacity were concurrently increased by 12.36%, 6.67%, and 3.88% respectively, but no big variance was found in the emission of CO2 when compared to diesel fuel. Heat release rate was decreased by 5.04% and cylinder peak pressure was improved slightly.
