Engineering Reports, Volume 7, Issue 5, May 2025.This study explores the impact of varying injection timings on a biodiesel‐hydrogen dual‐fuel CI engine. Results reveal that IT30 optimizes brake thermal efficiency (32.7%) and reduces CO and HC emissions while slightly increasing NOx. Findings suggest IT30 as the optimal configuration for balancing efficiency and emissions. ABSTRACT The growing demand

Journal of Engineering, Volume 2025, Issue 1, 2025.The world is currently facing a serious environmental crisis, partly driven by the pollutant emissions from diesel engines. Although these engines are known for their efficiency, their emission levels are highly dependent on fuel quality. In Colombia, despite having one of the highest‐quality fuels in the region, its properties still fall short of ...

Energy Science &Engineering, Volume 12, Issue 10, Page 4773-4787, October 2024.The authors comprehensively reviewed the fundamental reasons and mechanism of cycle‐to‐cycle variations (CCVs) of a spark ignition (SI) engine. In addition, the characteristic parameters and characterization methods of the CCV, the laws and influencing factors of the CCV, and the numerical simulation methods of the CCV were introduced in detail to ...

The effect of compression ratio on exhaust emissions from a PCCI diesel engine [PDF]
Energy Conversion and Management, 2007 Single cylinder engines are widely used for engine research because they allow isolation of the detail of behaviour within an individual cylinder rather than an average over multiple cylinders while eliminating the inter-cylinder interactions. A description of the development of a single cylinder test facility is presented, being based on a production ...
