초록 ▼

A hybrid vehicle having a hydrogen powered internal combustion engine employing a cylinder deactivation strategy during idle or light load conditions. A continuous stream of air is supplied to the hydrogen internal combustion engine. A control system responsive to engine speed and accelerator pedal position calculates a specific amount of hydrogen to inject into the continuous air stream. The resulting stream is combusted in the engine to provide power to the vehicle. During idling or light load conditions, the hydrogen supply to one or more cylinders may cease while maintaining the flow of air to the cylinders. A rechargeable battery and an electric motor receiving power from the battery are used to supplement the hydrogen powered internal combustion engine.

1. A hybrid electric vehicle comprising:a throttleless hydrogen powered internal combustion engine including one or more cylinders supplied with one or more unthrottled air streams, said one or more unthrottled air streams being supplied with hydrogen prior to entering said one or more cylinders;an electric motor supplementing said hydrogen internal combustion engine;a rechargeable battery for powering said electric motor; anda metal hydride hydrogen storage unit in gaseous communication with said one or more unthrottled air streams, said metal hydride hydrogen storage unit including a pressure containment vessel at least partially filled with a hydrogen storage alloy. 2. The hybrid electric vehicle according to claim 1, further comprising a hydrogen fuel control system. 3. The hybrid electric vehicle according to claim 2, wherein said hydrogen fuel control system provides a fuel control signal to one or more hydrogen fuel injectors in gaseous communication with said one or more unthrottled air streams based on the position of an accelerator pedal and the speed of said throttleless hydrogen internal combustion engine, said fuel control signal controlling the amount of hydrogen injected into said one or more unthrottled air streams. 4. The hybrid electric vehicle according to claim 3, wherein during idling or light load conditions one or more of said hydrogen fuel injectors cease injecting hydrogen into one or more of said unthrottled air streams. 5. The hybrid electric vehicle according to claim 1, wherein said one or more air streams entering said one or more cylinders have a λ value between 1 and 10. 6. The hybrid electric vehicle according to claim 5, wherein said one or more air streams entering said one or more cylinders have a λ value between 3 and 8. 7. The hybrid electric vehicle according to claim 6, wherein said one or more air streams entering said one or more cylinders have a λ value between 5 and 7. 8. The hybrid electric vehicle according to claim 1, wherein said throttleless hydrogen powered internal combustion engine has a compression ratio between 12:1 and 15:1. 9. The hybrid electric vehicle according to claim 8, wherein said throttleless hydrogen powered internal combustion engine has a compression ratio of 13:1. 10. The hybrid electric vehicle according to claim 1, wherein said rechargeable battery compensates for power loss resulting from powering said throttleless hydrogen powered internal combustion engine with hydrogen instead of a hydrocarbon fuel. 11. The hybrid electric vehicle according to claim 1, wherein said rechargeable battery provides a voltage greater than or equal to 12 volts. 12. The hybrid electric vehicle according to claim 1, wherein said rechargeable battery provides a voltage greater than or equal to 24 volts. 13. The hybrid electric vehicle according to claim 1, wherein said rechargeable battery provides a voltage greater than or equal to 36 volts. 14. The hybrid electric vehicle of claim 1, wherein said rechargeable battery has a peak power density of at least 700 Watts/kilogram. 15. The hybrid electric vehicle of claim 1, wherein said rechargeable battery has an energy density of at least 70 Watt-hours/kilogram. 16. The hybrid electric vehicle of claim 1, wherein said rechargeable battery has a peak power density of at least 1000 Watts/kilogram. 17. The hybrid electric vehicle of claim 1, wherein an exhaust stream from said throttleless hydrogen powered internal combustion engine is in thermal contact with said hydrogen storage alloy.
