Utilization of biodiesel as alternative fuel results in higher emission of oxides of nitrogen (NOx) and reduced performance parameters. The emission of NOx and performance parameters can be controlled by additives. Exhaust gas recirculation (EGR) is also a good technology to control the emission of NOx, but use EGR reduces the performance parameters of diesel engines. So to use additives with EGR has been a good option from emission and performance point of view. One more concept, nowadays in practice, the magnetization of fuel helps to make the combustion complete and hence reducing emissions and increasing performance parameters. In the present investigation, Jatropha biodiesel has been used with diesel in the form of a blend (BD20). 5% Ethanol has been used as an additive along with biodiesel blends and 10% EGR has been used to control NOx emission. The magnetization of fuel has been done with the help of a permanent magnet having strength of 3000 gauss. The results of this investigation show that the use of BD20 as fuel is beneficial for reducing emissions like CO, HC, and smoke but it reduces Brake Power (BP) and Brake Thermal Efficiency (BTE). The use of BD20E5 as fuel gives better performance parameters than the BD20, but the emission of HC increases slightly. Use of 10% EGR helps to control NOx emission but on the small cost of performance parameters. The magnetization of fuel provides complete combustion hence plays a vital role in improving performance and emission parameters.
