For transportation & mechanized Agricultural equipments, IC engine play as vital role in real life. So the consumption of diesel and petroleum is upsurged. India having heavy population, lots of waste cooking oil is wasted. If Waste cooking oil is used as biodiesel for alternative source of diesel, as diesel & petroleum are non conventional source of energy. Exhaust gas emitted from compression ignition (C.I.) engine is a mixture of many undesirable constituents known as pollutants like oxides of nitrogen (NOx), HC, CO, etc.. In this paper we are going to investigate emission and performance characteristics of waste cooking oil from diesel engine using Exhaust Gas Recirculation (EGR). EGR is a technique reducing the oxides of nitrogen (NOx) emission from diesel engine. A Single cylinder, water cooled, constant speed direct injection diesel engine was used for this experiment. The graphs were plotted comparing the emissions from diesel fuel and Waste cooking oil biodiesel fuel without EGR and with 5%, 10%, 15% EGR.
