ARM-2025_10 Minute Video_(Hafiz Muhammad Waqas Badar)

In this video, a PhD student presents their research on characterizing hydrogen combustion in a spark-ignition engine using a 2-zone thermodynamic model (CALMEC). The goal is to better understand the influence of air-fuel ratio (lambda) and spark advance on engine performance, efficiency, and emissions in hydrogen-fueled engines. The presentation outlines the type, strategy, and methodology of the research, combining experimental data from a single-cylinder engine with advanced diagnostic and predictive modeling tools (CALMEC, GT-Suite, and VEMOD). The speaker explains key hydrogen combustion characteristics, compares port fuel injection (PFI) and direct injection (DI), and discusses both advantages and challenges of using hydrogen as a clean alternative fuel. The talk also details the research hypotheses, objectives, and work plan and concludes with a discussion of potential risks and how they are mitigated. The ultimate aim is to support the development of efficient, low-emission hydrogen engines for future mobility.
