Abstract
The study focuses on the CFD modelling and analysis of the passive pre-chamber ignition concept, a promising technology for enhancing combustion efficiency in future-generation spark-ignition (SI) engines. By leveraging advanced computational fluid dynamics (CFD) tools, the investigation explores the complex interactions between turbulent jet ignition and in-cylinder flow dynamics. The passive pre-chamber system, which relies on pressure-driven fuel-air mixture exchange without active injection, offers potential benefits in terms of reduced ignition delay, improved flame propagation, and lower emissions. This analysis provides critical insights into optimizing pre-chamber geometry and operating conditions to support the development of cleaner and more efficient SI engines.
