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, NOX 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.Keywords

This paper deals with the design of multi flux three phase Slip ring induction motor using hybrid GA-PSO Genetic Algorithm Particle Swarm Optimization) technique. Multi flux Slip ring Induction motors are widely used in a number of renewable energy applications. In this paper the algorithm considers the two criteria: efficiency and power factor as objective function The hybrid GA-PSO is used to find a set of optimal design variables of the motor which are then used to predict performance indices and the objective functions.. PSO and GA are heuristic search methods being more flexible and robust and reliable in giving better quality. PSO is combined with GA for good knowledge sharing and synthesizes the merits of both GA and PSO, and it is a simple and yet effective model to handle different kinds of continuous optimization problems Due to their simplicity and efficiency PSO and GA are used in this research to develop efficient, and flexible algorithms to design an multi flux induction motor The rotor used in this multi flux induction motor is slip ring rotor where the staring torque can be varied in the slip ring counterpart so very high torque can be achieved by using the external resistance in the rotor circuit.
