Experiment has conducted to estimate the effect of cow urine fumigation on performance and emission
characteristics of single cylinder, air cooled and constant speed CI engine. Fumigation mechanism so connected that fumigated
PCU enters in to combustion chamber along with atmospheric air during suction stroke for 4 ml/min, 6 ml/min, 8 ml/min, 10
ml/min and 12 ml/min flow rate of PCU. It’s observed that performance parameter like Brake Thermal Efficiency (BTE), BSFC
improves up to 8 ml/min flow rate of PCU; further increase reduces the same parameter. For 8ml/min flow rate of PCU 5.02 %
BTE increases compare to without fumigation of PCU, also for same condition 0.253 Kg/hr reduction of Fuel Consumption has
observed as well as significant reduction in value of Exhaust Gas Temperature (EGT) observed, hence drastic reduction of NOx
formation founded for every load condition throughout entire test. Also observed that CO and HC emission reduces or remain very
close to the emission by only diesel fuel till 8 ml/min flow rate of PCU. CO2 emission increases up to 10 ml/min flow rate of PCU
and then decreases for further increase of PCU flow rate.
