Computational fluid dynamic analysis of the effect of inlet valve closing timing on common rail diesel engines fueled with butanol–diesel blends (2024)
Journal Article
Lamani, V. T., Shivaprasad, K. V., Roy, D., Yadav, A. K., & Kumar, G. N. (2024). Computational fluid dynamic analysis of the effect of inlet valve closing timing on common rail diesel engines fueled with butanol–diesel blends. Frontiers in Energy Research, 12, 1447307. https://doi.org/10.3389/fenrg.2024.1447307

The inlet valve closing (IVC) timing plays a crucial role in engine combustion, which impacts engine performance and emissions. This study attempts to measure the potential to use n-butanol (Bu) and its blends with the neat diesel in a common rail di...
