Bosch invests in hydrogen combustion engine: Production still in 2024. Hydrogen engine has advantages over fuel cell: Less weight and more efficient.
Hyundai also wants to bring a hydrogen engine in 2025. And Yamaha is also working on a V8 engine. Unlike diesel and gasoline, hydrogen attacks lubricating oils and destroys the carbon macromolecules. It therefore has no lubricating properties and can combine with materials in the engine block. The pistons therefore need additional lubrication, as AutoBild writes.
