AB - Direct injection diesel engine combustion system offers improvements in  performance and fuel economy benefits. 4 valves per cylinder, turbocharged  and intercooled diesel engine became trustworthy for automobile application.  Electronic diesel control, use of common rail with increase in injection  pressures, and flexibility in injection control has changed the image of  diesel engine. Evolutions in piston crown shape, intake ports with different  swirl level helped to enhance mixing of air and fuel for better performance  and emissions. In this describe the work done on 4 cylinder diesel engine,  upgraded to BS5 (Bharat stage 5) emission norms with 20% power increase. A  systematic approach of engine development was fallowed. Engine performance  prediction was done using AVL Boost software. Boost Model was validated with  existing engine cylinder pressure. Combustion parameters have been varied to  predict higher power. Vehicle model has been build using AVL cruise software  and used to obtain steady state load- speed points. Engine emission  development has been done on engine test bench. Typical hardware like piston  crown, turbocharger, EGR system with EGR cooler and various combustion  parameters were tested and optimized. Suitable after-treatment system was  selected optimized for precious metal loading reach Bharat stage 5 emissions.
