Experimental investigation on CI engine with jatropha biodiesel-hydrogen peroxide blends

Abstract

The main objective of this research attempt is to determine implications of applying hydrogen-based additives as diesel and biodiesel oxygenates. Due to the difference in additive polarity, blending of hydrogen-based additives and petroleum diesel-biodiesel fuel mixtures require emulsification process towards achieving a stable mixture. After emulsification, stability test was conducted. experimentations were conducted on a single cylinder diesel engine fuelled with petroleum diesel and jatropha oil methyl ester diesel blends with hydrogen peroxide introduction at different loads and different injection operating pressures. From the experimentations it was observed that Introductions of H2O2 improve the brake thermal efficiency of the engine for D60-B30-A10 blend at 80% load and at 205 bar I.O.P. And also, extreme reduction in C.O. and H.C. emission was observed at all loads. NOx increased relatively with the escalation of hydrogen based additive concentration. It can thus be concluded that introduction of hydrogen can improve the engine performance and emissions. D60-B30-A10 gave the best engine performance and emissions at 205 bar I.O.P., 17.5 CR, 230 bTDC injection timing and 1500rpm.
