Active Hydrogen prechamber technology to run up to lambda 7

A remarkable milestone has been achieved in hydrogen engines by introducing a groundbreaking pure hydrogen engine that operates at an impressive air-to-fuel ratio (AFR) of 7. This means that for every gram of hydrogen combusted in the engine, approximately 238 grams of air are utilized, highlighting the engine's efficient use of hydrogen as a fuel source.

Originally designed to run on gasoline, this spark ignition engine has undergone significant modifications, showcasing its exceptional adaptability and versatility. It now demonstrates the capability to operate efficiently with 100% hydrogen, maintaining stable combustion across a wide range of air-to-fuel ratios, specifically between AFR 1 and 7. This performance is particularly noteworthy given that the engine is based on a direct injection (DI) platform that has been developing for 15 years, marking a significant leap in technological advancement.

One of the standout features of this hydrogen engine is its ability to function effectively under ultra-lean conditions, which allows it to outperform conventional gasoline internal combustion engine (ICE) platforms. This advancement opens up exciting possibilities for real-world applications, particularly in reducing greenhouse gas emissions and reliance on fossil fuels, given hydrogen's potential as a clean energy carrier.

However, this breakthrough also raises important questions regarding the limits and boundaries of a dedicated hydrogen internal combustion engine platform. As this technology continues to evolve, exploring its implications for the automotive industry, infrastructure requirements, and overall sustainability will be essential. This innovation could pave the way for a new era in transportation, emphasizing the need for further research and development in hydrogen-powered technologies.
