Experimental investigation of emission reduction in 4S diesel engine fueled by coconut oil Methyl Ester(ME) using oxidation inhibitors

Abstract

As non-renewable fuels become increasingly depleted and the environmental impact of burning petroleum fuels becomes more evident, the search for alternative fuels has intensified. One promising alternative is vegetable oils derived from biomass. However, when utilized in diesel engines, the carbon content and high viscosity of these vegetable oils can cause significantly lower performance and increased smoke emissions. The transesterification process can be utilized to enhance the performance of vegetable oils, which would be a solution to this problem. This research examined the feasibility of using a 4-stroke direct injection diesel engine on ME of coconut oil. The findings shown that diesel engines can function properly when utilizing only coconut oil as fuel.
