Abstract: A method for supplying hydrogen-operated internal combustion engines with oxygen, wherein an inert gas is cycled. An economical local supply of pure oxygen for a closed-cycle hydrogen engine with argon cycling is realized by separating the oxygen from the atmosphere without relying on the useful work of the engine. OSM ceramics and exhaust gas heat and low oxygen partial pressure of the exhaust gas are used to generate oxygen. Two reactors filled with OSM ceramics are used, these reactors being alternately purged with exhaust gas and regenerated with air. Losses of inert gases and the entry of atmospheric nitrogen are avoided by intermediate purging with steam. The steam is generated by the heat of the exhaust gas or exhaust air. A mixture of water vapor, inert gas and oxygen is formed during purging. Subsequently, the oxygen content in the gas phase is markedly increased since water vapor is condensed out.

Abstract: A mass-flow throttle for highly accurate control of the gaseous supplies (fuel and/or air) to the combustion chambers for a large engine in response to instantaneous demand signals from the engine's ECM, especially for large (i.e., 30 liters or greater in size) spark-ignited internal combustion engines fueled by natural gas. With a unitary block assembly and a throttle blade driven by a non-articulated rotary actuator shaft, in combination with tight control circuitry including multiple pressure sensors as well as sensors for temperature and throttle position, the same basic throttle concepts are innovatively suited to be used for both MFG and MFA throttles in industrial applications, to achieve highly accurate mass-flow control even despite pressure fluctuations while operating in non-choked flow.

The engine may be provided in a configuration generally suited for swirl flow, compression combustion fuel usage.

Abstract: Engine controllers and control schemes that facilitate skip fire engine operation in conjunction with use power take-off devices are described. In one aspect, a skip fire mode is exited when the power take-off unit is engaged and the current torque request exceeds a torque threshold. In some embodiments, the exit is delayed when the temperature of an after treatment system is below a designated temperature threshold. In another aspect, the engine transitions to the skip fire mode when the power take-off unit disengages. In some embodiments, exiting is conditioned on the current torque request being less than a torque threshold. In some embodiments, the transition is made immediately, whereas in others the transition only occurs when the power take-off unit is not reengaged for a period of time or is further conditioned on determining that the power take-off unit is likely to remain disengaged for the period of time.
