Appl. No.:

11/583329

Inventors:

Justin Fulton - Fort Collins CO, US
Franklin Earl Lynch - Bailey CO, US

Assignee:

Brehon Energy PLC - Littleton CO

International Classification:

F02B 47/08
F02B 47/10

US Classification:

12356817, 123DIG 12

Abstract:

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.

International Classification:

US Classification:

Abstract:

Gas flow is controlled to a feed gas consuming device depending on whether a contaminant gas is present. In one embodiment, hydrogen gas flow from a hydrogen gas generator to a hydrogen consuming device, such as a fuel cell, gas chromatograph or a flame ionization detector, is terminated when there is chemical contaminant breakthrough in the hydrogen gas flow. The apparatus relates to the use of a sensor for detecting a predetermined concentration of a chemical contaminant such as ammonia. In one embodiment the apparatus terminates the gas flow when a concentration of ammonia in the gas flow corresponds to a breakthrough (e. g. , approximately in the range of 2. 0% or greater). The apparatus prevents the ammonia-contaminated hydrogen from disabling such a hydrogen consuming device that would have otherwise received the contaminated gas flow. The apparatus terminates such a hydrogen contaminated gas flow by exposing a breakthrough detection material to the gas flow, wherein this material is substantially only reactive to concentrations of a predetermined contaminant (e. g. , ammonia) for terminating the gas flow when such concentrations are indicative of a breakthrough of the contaminant.

123698, 12356811, 123DIG 12, 701108

Abstract:

A system includes a hydrogen fueled internal combustion engine, a fuel system configured to provide a flow of hydrogen fuel to the engine, and an exhaust gas recirculation (EGR) system configured to provide a flow of recirculated gas to the engine which includes exhaust gases. The system also includes an engine controller configured to control the fuel system and the EGR system, such that the engine receives a mixture which includes the hydrogen fuel, the ambient air and the recirculated gas in a stoichiometric fuel/air ratio that meets the torque demand on the engine. A method includes the steps of providing a flow of gaseous hydrogen fuel, a flow of ambient air, and a flow of recirculated exhaust gas to the engine. The method also includes the steps of mixing the flow of recirculated exhaust gas and the flow of ambient air, determining a flow of hydrogen fuel necessary to create a stoichiometric fuel/air ratio, and then regulating the hydrogen fuel flow to control the torque of the engine, minimize throttling work and provide a mixture comprised of the hydrogen fuel, the ambient air and the exhaust gas in a stoichiometric fuel/air ratio.

International Classification:

US Classification:

252184

Abstract:

A sorbent composition for reducing the stress buildup within sorbent alloys such as hydride powders being used to store hydrogen gas by imparting more of a fluid-like property to the alloys. Under the teachings of the present invention, a second powder is added to the powdered sorbent alloy to serve as a flow aid to the alloy powders so as to allow rearrangement and movement for the alloy powders with respect to each other and with respect to the sidewalls of the container. The flow aid powder which is chemically inert with respect to hydrogen and the sorbent alloys is mixed with the sorbent alloy powder and the amount of the flow aid powder is dependent upon the volume change of the particular hydride, the strength of the container, the geometry of the container, the orientation of the container, and the direction of the reaction front. The addition of the flow aid reduces densification, compaction, settling, and stress buildup during successive cycles of absorption and desorption.
