Abstract


Objective: In this research article performance and exhaust emission of compression ignition engine coupled with electric generator set was analysed by using fuel bakain methyl ester as a new renewable energy source. Methods/Statistical Analysis: Seeds of Bakain, Family- Meliaceae, English-Persian lilac, Hindi- bakain were collected from local area of longowal and oil was extracted. Oil collected from Bakain seeds was transesterificated into Biodiesel. Fuel properties viscosity, calorific value, flash point and fire point of Bakain methyl ester were tested and recorded as per ASTM D. Electric generator set operated by compression ignition engine used Bakain methyl ester as fuel under different loading condition. Findings: Performance and exhaust emission of electric generator set operated by compression ignition engine used bakain methyl ester and mineral diesel were compared under 0.1 kW ,1.5 kW, 3kW and 5 kW load condition. There was slightly drop in overall efficiency of electric generator set when used bakain methyl ester as compare to mineral diesel fuel under same load condition. 2.77% less of overall efficiency drop of electric generator set was observed when used Bakain methyl ester as compare to mineral diesel fuel at 5 kW load. Electric generator set coupled with compression ignition engine consumed more bakain methyl ester as compare to mineral diesel fuel at same load condition. There was 96 gm/kW quantity of fuel consumed more when used bakain methyl ester as compare to mineral diesel fuel. Exhaust emission of CO, CO2, NOx and flue gas temperature of electric generator set were also recorded for bakain methyl ester and mineral diesel fuel under different load condition. Electric power generator set emitted 4 % more NOx when used bakain methyl ester as fuel in comparison to mineral diesel at 5 kW load.8 % less carbon dioxide CO2 emitted from electric generator set when used bakain methyl ester as fuel in comparisons to mineral diesel operated at 5 kW load condition. Higher flue gas temperature of electric generator set was recorded when used bakain methyl ester as compare to mineral diesel as a fuel at same load condition. Application/Improvement: Biodiesel from bakain seeds new renewable energy source can be produced and use as a fuel in compression ignition engine to generate electric power with slightly compromising power and less impact on exhaust emission.
