This project explored how new swirl piston bowl designs can reduce diesel engine emissions and boost performance. By testing multi- and double-swirl bowls with various spray angles and pressures, soot was cut by up to 81%. However, higher swirl also raised NOx levels, highlighting the importance of optimizing injection parameters to balance efficiency and emissions.
This project used numerical simulations to test six different piston bowl shapes in a diesel engine running on n-heptane. Results showed that designs DE and DF delivered better combustion and lower emissions than the others, but at the cost of slightly higher NOx levels. Overall, the study highlights how bowl geometry significantly impacts engine efficiency and emission trends.
In this project, various intake manifold designs were tested (using CFD) to meet Formula SAE rules requiring a restrictor that limits engine output. By optimizing airflow distribution across four cylinders, newer designs achieved a more balanced flow compared to earlier versions, improving overall efficiency under strict competition requirements.
