STUDY THE EMISSION CHARACTERISTICS OF COMBUSTION IGNITION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 4, Issue 7
Abstract
A study was conducted on fuel blends prepared using diesel and refined soybean oil combinations compatible with diesel fuel as used in CI engines. A stationary 3.73 kW Kirloskar make single cylinder compression ignition diesel engine having 27° BTDC (standard injection timing) was tested as per IS 10000 - 1980 on diesel and prepared diesel blends. The performance tests of the engine were carried on at no load, 2 5, 50, 75, 100 and 110 % brake load conditions and emission of CO, UBHC and NOx was evaluated for each fuel blends. The emission of CO, UBHC, nitric oxide and nitrogen dioxide from the engine on diesel - refined soybean oil blends was in the range of 0.21 to 0.85%, 0.01 to 0.16%, 12.7 to 317 ppm and 3.8 to 41 ppm, respectively. The results indicated that the emission of CO and UBHC on the selected blends was found comparable but the NOx level was found to be higher than the diesel. A blend having diesel - r efined soybean oil mixed in 80:20 proportion replacing 20 percent diesel may be selected for fuel use in CI engines
