Abdu's study, by employing physical one-dimensional and three-dimensional computational fluid dynamics (CFD) tools used in conjunction with supercomputing resources, further illustrates how fully variable valvetrain systems can be fine-tuned to achieve optimal performance across various engine architectures, including both four-stroke and two-stroke configurations. Through the detailed evaluation of scavenging and trapping efficiencies, this research provides valuable insights into the potential for NOx reduction in ICEs equipped with Freevalve technology. The findings highlight how these advanced control strategies can help address the dual challenge of reducing CO2 and NOx emissions through efficiency metrics, ensuring that ICEs remain a viable and environmentally responsible option in the evolving energy landscape.
