Abstract: A system and method to control spark in a cylinder of a multi-cylinder engine. Spark can be controlled in a cylinder based on operating conditions of a selectively operable valve.

Abstract: A system and method to control engine valve timing to improve the start of an internal combustion engine. Electromechanical valves are controlled in a manner to reduce hydrocarbon emissions during the start of an internal combustion engine.

Abstract: A method of operating a hybrid fuel cell system within a state of charge window of a charge carrier such as a battery pack, improves system efficiency by reducing use of the fuel cell to charge the battery pack. Power is drawn in relative amounts from the fuel cell and the charge carrier based on a control strategy that considers the charge carrier's state of charge, overall load power requirements and the maximum power output capacity of the fuel cell.

Abstract: A method to compute, store, and inject adaptive valve timing corrections in a camless valvetrain architecture where a measurable (based on the resolution of the measuring methodology) error exists between the requested and delivered valve timing. This method is based on a measurement of the delivered valve timing, such as from a direct position sensor, (hall effect, LVDT, optical, etc.) or inferred position sensing based on valve actuator current (electronic actuation) or pressure (hydraulic actuation) feedback. This measured delivered valve timing information is used to compute offsets which, when applied to the desired timing, provide more accurate correlation between the delivered timing and the desired timing.
