  • Abstract

In order to meet the current and estimated future global energy consumption and to reduce the hazardous environmental pollution due to hefty usage of fossil fuels in the fields of transportation and industries foster the research on renewable energy sources. The previous research studies revealed that plant based oils, waste cooking oils, and animal fats can be used as biodiesel to reduce the dependence on fossil fuels, to reduce the foreign fuel imports, lower the green gas emissions and uplift the rural economies. The objective of the present research study is to evaluate the impact of engine parameters on CO emission of diesel engine fuelled with Jatropha curcas oil methyl ester (JCOME). This work investigates the factors that influence the CO with lesser emission effect. Fuel injection pressure, percentage of blend of JCOME and engine load was considered as the factors for the objective and CO emission were considered as the response variables. L16 orthogonal array was prepared using design of experiments methodology and series of experimental tests were carried-out as per designed array with different combination of influencing factors. Taguchi method was applied to evaluate the influencing factors and significance of impact on response variables. The results of taguchi experiments revealed that that injection pressure 220 bar, blend BJ40 at 25% of engine load were optimum parameter setting for lowest CO emission. Engine’s CO emission is mostly influenced by engine load, blend percentage of JCOME and is least influenced by injection pressure.
