Book excerpt: India, being second largely populated country in the world and 70% of its population depends on agriculture as their main job. Stationary CI engines find wide applications in agricultural area for pumping water, power generation and other crop processing works. Even though emission regulations for such engine applications do not come under stringent norms, their contribution cannot be overlooked. NOx(Oxides of Nitrogen) is considered as one of the most objectionable pollutant from diesel engine. Exhaust Gas Recirculation (EGR), has long been of interest to engine designers, researchers, and regulating authorities in abating NOx. Implementation of EGR for naturally aspirated stationary diesel engines are relatively simple and a study of the application of high level EGR on such an engine is carried to study its impact on the other performance parameters. The results of this investigation give insight into the effect of EGR level on the development of gaseous emissions as well as mechanisms of its formation. Reductions in NOx amount are found to be remarkable with EGR but combustion quality deteriorates at higher loads and higher percentages of EGR due to a significant decrease of A/F ratio. EGR up to 60% is found optimum with 190 bar injection pressure without sacrificing thermal efficiency and increase in unburned HC significantly.
