This study investigates the effect of antioxidants namely N‐Phenyl‐p‐phenylenediamine (DPD), N, N‐Dimethyl‐p‐Phenylenediamine Dihydrochloride (NPPD) and Succinimide (SU) as a fuel additive for Jatropha biodiesel. The antioxidant additives are added to biodiesel and its blend separately at a dosage of each 1000 parts per million (ppm) and the experimental investigations are conducted to study the effect of antioxidants dispersed biodiesel and biodiesel blend on the performance and emission characteristics of the diesel engine operated at a constant speed of 1500 rpm, constant injection timing of 215 bar and constant injection of 26 bTDC (Before Top Dead Centre). The experimental results revealed that B20SND1000 test fuels established 7% improvement in brake thermal efficiency and substantial percentage reduction of nitric oxide (NO) emission by 22% for B20SND1000 test fuel, when compared to B100.
