Toyota Water-Cooled Engine.
quote:
Toyota's recently filed patent for a water-cooled hydrogen combustion engine marks a significant step in their exploration of alternative powertrains beyond full electrification. This innovation addresses the challenge of higher operating temperatures inherent in hydrogen engines compared to traditional gasoline ones, potentially paving the way for high-performance hydrogen vehicles.
From what I can find the new hype is wrong. The engine does not produce its own hydrogen but only controls the excessive heat a hydrogen engine produces. No on-board electrolysis.
The new water-cooled tech is for use dissipating the excessive heat a hydrogen combustion engine produces as it runs.
I find no where on the trusted sites any mention of on-board electrolysis technologies incorporated into an internal combustion hydrogen engine.
