To meet stringent vehicular exhaust emission norms worldwide, several exhaust pre-treatment and post treatment techniques have been employed in modern engines. Exhaust Gas Recirculation (EGR) is a pre-treatment technique, which is being used widely to reduce and control the oxides of nitrogen (NOx) emission from diesel engines. EGR controls the NOx because it lowers oxygen concentration and flame temperature in the combustion chamber. The experiments were carried out to experimentally evaluate the performance and emissions for different EGR rates of the engine using A20 (20% Annona Methyl Ester + 80% Diesel) as a fuel. Emissions Parameters such as hydrocarbons (HC), NOx, carbon monoxide (CO), and smoke were measured. Performance parameters such as brake thermal efficiency, brake specific fuel consumption (BSFC) were also calculated. It is concluded that for the A20 blend of Annona Methyl Ester (AME) shows reduction in NOx was observed without any engine modification.
