Ford patents a hydrogen combustion engine
Ford’s new patent includes direct injection to deliver hydrogen to the cylinders.
Ford has filed a patent with the US Patent and Trademark Office for a recently discovered hydrogen-powered combustion engine, Muscle Cars and Trucks. In a typical hydrogen vehicle, a propulsion system similar to that of an electric vehicle is used, where the energy stored in the form of hydrogen is converted into electricity by the fuel cell.
Ford’s new patent, however, is for a hydrogen-powered turbocharged combustion engine. And on paper, the company’s engine will be able to operate over a wide range of air/fuel lambda values. Just like in a traditional internal combustion engine, exhaust gas recirculation (EGR) and valve timing would be used to control the combustion process.

The patent also includes direct injection to deliver hydrogen to the cylinders and delivering hydrogen by direct injection could produce up to 15% more power than an equivalent gasoline engine. Patent documents show the hydrogen combustion engine as part of a hybrid powertrain with a motor-generator positioned between the engine and transmission. However, the patent only covers the method of combustion and control of hydrogen mixtures, not the entire engine.
It cannot be said at this time whether the patent will actually reach a production stage at any given time. Some of Ford’s recent patents include technology that lets you drive a car with your brain, and a deployable drone patent, among others.
The discovery of Ford’s new patents comes after the company earlier this month announced it is splitting its business into two separate divisions. The company has a number of all-new electric vehicles currently in development under the Model E. While the Blue Oval division will be working on combustion models.
