Sandia addresses barriers to hydrogen-fueled internal combustion engines

News Article, November 18, 2024 • Pre-ignition is one of the key barriers preventing hydrogen-fueled combustion engines from achieving efficiency and power-density parity with current diesel powertrains. To address this issue, Sandia has developed an experimental framework to isolate and study various sources of pre-ignition. The research team recently updated the framework with a new methodology...
