Effect of Egr on C.I Engine Emissions and Cooling Rate using diesel and ethanol blends

Emission control has become a major problem in the society and indiscriminate usage of motor vehicles increases a lot of pollution, mainly in cities. Diesel is a non-renewable energy source and used more than petrol or gasoline and also the emissions of the diesel engine create a lot of havoc especially ecological imbalance. According to the studies referred in the literature the use of bio-fuels especially ethanol along with EGR can reduce particulate matter and nitrogen oxide (NOx). The main aim of this paper is to evaluate the emission characteristics Nitrogen oxides (NOx), carbon dioxide (CO2), carbon monoxide(CO), Hydrocarbons(HC)emissions of four stroke single cylinder diesel engine by using exhaust gas recirculation(EGR) at various blends of diesel, ehanol and propanol and also emissions of exhaust gas of Nitrogen oxides(NOx)), carbon Dioxide(CO2), carbon monoxide(CO), Hydrocarbons (HC) emissions) using EGR at normal and varying the cooling rates at peak load.
