Scientists Probe the Source of Stochastic Occurrence of Super-Knock in Engines Running on Hydrogen/Methane Fuels
Department of Energy, Office of ScienceBlends of hydrogen and methane are a promising alternative vehicle fuel that could help reduce carbon dioxide emissions. To make these fuels viable, researchers need to understand how they burn, especially in small, turbocharged internal combustion engines. In this study, researchers examined the impact of non-thermal chemical kinetics on “super-knock,” a combustion mechanism that can cause severe engine damage.
