Ignition Investigation of Pure Biodiesel in A Research Engine with Dual Fuels

Abstract

Under the effect of acetylene (C₂H₂) as a secondary energy in diesel engines powered by Acacia methyl ester (ABD) is investigated in this study. This experimental work is carried out on single cylinder, water cooled, direct injection diesel engine.  At the intake manifold air and C₂H₂ was combined and mixture will have specific stream rate (2 and 4 lpm). In a diesel engine, the ignition analysis of changed fuels under varied Mean Effective Brake Pressure (BMEP) is assessed and contrasted with diesel by adjusting the apparatus load between 01 and 05 BMEP. This research looks at C₂H₂ as a sustainable twin fuel with the goal of lowering diesel apparatus emissions while improving performance. Experiments demonstrated that supplying C₂H₂ at 2 and 4 Litres per minute (lpm) results in faster flame velocity and greater flammability for ABD, resulting in enhanced efficacy and improved combustion patterns. Because of its higher flammability and longer C-H chain, acacia methyl ester with acetylene (ABD-C₂H₂) at 2 lpm and ABD-C₂H₂ at 4 lpm reduced hazardous diesel motor exhaust compared to biodiesel alone. According to the findings of this investigation, adding acetylene at varied flow rates improves biodiesel's ignition patterns in a diesel engine with no changes.
