Evaluation of emission, performance and combustion characteristics of dual fuelled research diesel engine

ABSTRACT

This study is intended to examine the ignition characteristics of a cashew nut shell biodiesel (C100) along with ethyne (acetylene) as a dual fuel in a diesel engine. Cashew nut shell oil is employed in this study owing to non-toxic nature, free from sulphur, biodegradable, and free of aromatics. Ethyne gas was introduced at different flow rate of 2, 4, 6 litres per minute (lpm). Experimental results revealed that duel fuelling ethyne gas to base fuel (C100) at 6 lpm reduce 18.1% CO, 9.7% HC, 6.87% Smoke with 11.1% increase in NO_x emissions. Higher thermal efficiency was observed for ethyne–biodiesel mixture than neat biodiesel in all flow rates. Furthermore, the heat release and peak pressure were enhanced by duel fuelling ethyne gas to base fuel (C100).
