▲ Ford's new patent diagram shows the design of a hydrogen fuel internal combustion engine, and can be used as a direct injection in the cylinder to make the exhaust cleaner by thin combustion.
Although Ford in North America only recently assigned electric vehicles to the Model E division for development, a recent patent diagram is also quite special, because the patent indicates that Ford is developing a hydrogen-fueled internal combustion engine, unlike the generally recognized hydrogen fuel model, this patent is a hydrogen-fueled turbocharged engine.
It is understood that this hydrogen turbine engine can operate in a wide range of Air/Fuel air-fuel ratio (Lambda), just as the combustion process is controlled by the EGR waste cycle and valve timing in an internal combustion engine. From the patent diagram, the lambda value (excess air coefficient) of this hydrogen fuel engine can exceed 2.00, far exceeding the 1.00 of thin combustion, and it is cleaner in exhaust.
Although this patent may not be mass-produced, it can also be seen that the car manufacturer has not completely abandoned the internal combustion engine.
In addition, the patent also includes a design for direct hydrogen injection in the cylinder, which theoretically can produce up to 15% more power than gasoline, and Ford regards this patent as part of the hybrid system, and there is an electric motor between the engine and the gearbox, so the patent only covers the way to burn and control the hydrogen mixture, and does not include the engine body.
Although the entire patented design is complex and may not necessarily be put into mass production, the study also shows that the automaker has not abandoned the internal combustion engine, hoping to improve the exhaust performance through improvements.
