Research Study on Performance and Emission Characteristics of Oxygen Enriched Combustion of Water Emulsified Palm Biodiesel

Environmental degradation is the major dilemma of present time. The depletion of environment is mainly due to pollutants emitting from exhaust of motor vehicle. Such pollutants are CO, NOx, CO2, HC, soot emission etc. Present research work is to controlling the amount of these pollutants from emission of single cylinder four stroke water cooled diesel engine and to find performance of diesel engine by combine effect of oxygen enrichment and water emulsification of fuel. The fuel used for research is diesel and diesel – palm biodiesel blend (PB10). Emulsification of diesel – palm biodiesel blend (PB10) are made with water concentration 5% and 10 % respectively and oxygen enrichment with 9 – 10% are used for present research work. The experimental results show that there are reduction in emission due to combine effect of oxygen enrichment and water emulsification. OED and diesel has a lower SFC than and all other blends. OEWIP 10% has lower emission of NOx while, OED and OEPB10 has higher value of NOx. OEWIP 5% and OED has lower emission of HC while, WIP 10% has a higher emission of HC.OEWIP 5% and OEPB10 has a lower CO2 than all other blends. Emission of CO is lower for WIP 5% and OEWIP 5% than other blends.
