Excerpt

The article delves into the development of hydrogen (H2) engine components for heavy-duty vehicles, focusing on the need to reduce CO2 emissions in the transport sector. It discusses the advantages of H2 engines over fuel cells for high-load, long-range applications and the potential to leverage existing combustion engine infrastructures. Key challenges such as combustion anomalies, H2 embrittlement, tribology, and corrosion are addressed. The article presents innovative solutions for H2-specific components, including aluminum pistons designed to minimize combustion residues and optimized piston ring packages to reduce blowby. It also explores the use of specific materials and surface solutions for valve sets to mitigate the unique challenges posed by H2. The development of these components aims to create a robust and future-proof H2 engine, paving the way for decarbonization in the transport sector.
