Effect of Exhaust Gas Recirculation on the Performances of Diesel Engine with Isobutonal Blends

Exhaust Gas Recirculation (EGR) System means to use the Exhaust Gas coming from Exhaust Manifold to inlet manifold in order to reduce the emission of NOX, which is particularly very harmful. Engine without EGR are more pollutant and uses more atmospheric air for combustion. By implementation of EGR system in engine, the partial exhaust gas is re-circulated again in engine. It is first cooled in EGR Cooler&then it is mixed with atmospheric air&then passed to Combustion Chamber. Fresh atmospheric air required is reduced&automatically pollutant (CO, CO2, HC, NO_X etc.) is reduced. In the present work is to review the potential of exhaust gas recirculation (EGR) to reduce the exhaust emissions, particularly NOX emissions, and to delimit the application range of this technique with different Isobutonal blends with diesel. In the present investigation brake mean effective pressure is highest at 5% of Isobutonal with 17.9225 of EGR and the brake thermal efficiency 22.65%. The Volumetric efficiency is almost same in all the cases and the brake specific fuel consumption is lower at 7% of Isobutonal with 22.65% of EGR. The system is very much Eco Friendly. Using Exhaust Gas Recirculation (EGR) Technique in engines, the emissions are very much controlled. This method is very reliable in terms of fuel consumption.
