Experimental Investigation on Two Cylinder Diesel Engine using Biodiesel and Diesel as Fuel with EGR Technique

Today major problems associated with the human being are environmental pollution. It is caused by so many exhaust gases like Nitrogen oxides (Nox), Carbon monoxide (CO), hydro carbon (HC) etc. To reduce the amount of NOx emission engine cylinder has to maintain temperature below 2500F. Exhaust gas recirculation (EGR) is one of the most effective ways for reducing NOx after emission in diesel engine. Two cylinder four stroke direct injection water control diesel engine is operates with Karanja Oil and pure diesel and the exhaust gas temperature efficiency, NOx and hydrocarbon, specific fuel consumption were compare for different percentages of hot and cold EGR for diesel and bio diesel.
