Future emission legislation for light commercial vehicles can be met through appropriate design of after – treatment devices like Diesel Oxidation Catalyst (DOC) for HC, CO and partial PM reduction andCooled –Exhaust Gas Recirculation (C-EGR) systems for NOx reduction for low cost solution. Computational analysis offer new possibilities for optimal design of DOC and C-EGR systems for low cost truck applications. Further the reduction in NOx emissions within the new legislation, forces the increase of EGR rates, for this EGR cooler with higher thermal dissipation capacity is required. Corrugated tube design for the cooler pipe increases the thermal efficiency of EGR cooler without affecting the engine performance. This paper provides the overview on exhaust flow uniformity index, pressure drop across the DOC and hot spot prediction in cooler tubes, pressure distributions inside the EGR cooler using Computational Fluid Dynamics (CFD). With the optimized DOC/C-EGR design the emission results are investigated on chassis dynamometer to meet BS-IV diesel emission norms. |
