Beyond BS-IV, meeting emission legislation is an exigent target for diesel engine manufactures. But there always exist a compromise between engine performance and emissions. However the development of proper combination of Fuel Injection Equipment (FIE) system along with low cost after-treatment development for Indian vehicle applications to reduce the emissions plays major role to meet the engine target cost. Therefore in this study significance of using K and Ks nozzle is experimentally investigated for its effect on emission performance. In addition to maintain proper NOx/PM trade-off, an increased EGR flow rate along with higher cooling efficiency is improved. This increase in cooling efficiency is made without compromising other requirements in the design of the EGR cooler. The buildup of carbon deposits in EGR coolers causes significant degradation in heat transfer performance, often on the order of 15% - 20%.
