A hydrogen-fueled internal combustion engine utilizes either internal or external exhaust gas recirculation (EGR), while providing an overall stoichiometric fuel/air ratio. An EGR system provides recirculated exhaust gas to the engine, and an engine controller regulates fuel flow to control torque and achieve a stoichiometric fuel/air ratio. A three-way catalyst can be applied to the exhaust gas to produce near-zero emissions. In addition, turbocharging or mechanical supercharging can also be used to increase power.
