Hydrogen Enrichment Strategies for CI Engine Research

Abstract

Hydrogen enrichment in compression ignition (CI) engines has emerged as a promising avenue to address the challenges of emissions reduction and enhance combustion efficiency. This paper presents a comprehensive investigation into various hydrogen enrichment strategies for CI engine research. Through a systematic review of recent advancements and experimental studies, this paper explores the impacts of hydrogen addition on combustion characteristics, engine performance, and emissions. Different methods of hydrogen injection, including port injection, direct injection, and dual-fuel strategies, are analyzed to assess their effectiveness in improving engine efficiency and reducing pollutant emissions. Additionally, the influence of hydrogen on combustion stability, ignition delay, and heat release characteristics is examined. Furthermore, the effects of hydrogen addition on engine durability, materials compatibility, and safety considerations are discussed. This paper aims to provide valuable insights into the potential of hydrogen enrichment for advancing CI engine technology and facilitating the transition towards sustainable transportation.
