Abstract: An internal combustion engine that includes an engine block assembly, an air intake system coupled to the engine block assembly and an alternative fuel delivery system coupled to the air intake system. The alternative fuel delivery system includes a control module that monitors measurements of operational data of the internal combustion engine from the one or more sensors. In response to the operational data, the control module determines a fuel flow rate of alternative fuel and controls injection of the alternative fuel to provide the determined fuel flow rate of alternative fuel into the air intake system.

Abstract: An internal combustion engine includes an engine block assembly, an air intake system coupled to the engine block assembly and a hydrogen delivery system coupled to the air intake system. The hydrogen delivery system includes a control module that monitors an air flow rate through the air intake system. The control module determines a desired volume or mass of hydrogen to be injected into the air intake system in response to the air flow rate to produce a hydrogen to air ratio. As the air flow rate changes, the control module 120 continually updates the desired amount of hydrogen to be injected into the air intake system to produce a predetermined hydrogen to air ratio. The control module controls the hydrogen injector to provide a flow rate of hydrogen fuel to the air intake system to deliver the desired volume or mass of hydrogen.
