Abstract: A carbon capture system includes a hydrogen production module. The hydrogen production module is used to control the amount of hydrogen entering an internal combustion engine to reduce an amount of water vapor generated by the internal combustion engine, thereby increasing the efficiency of the carbon capture device. If too much water vapor is detected in an exhaust of the engine, the amount of hydrogen produced by a hydrogen production module can be increased, thereby reducing the amount of hydrogen entering the engine and reducing the amount of water vapor generated by the engine. A reformer catalyst can be used by the hydrogen production module to remove at least a portion of hydrogen in a fuel stream of the engine.

Abstract: Operating an engine includes injecting a liquid alcohol fuel such as methanol into a stream of compressed intake air at an upstream injection location, and injecting the liquid fuel at a plurality of downstream injection locations into a plurality of streams of the compressed intake air from an intake manifold to combustion cylinders in the engine. A fueling control unit apportions a total injected quantity of the liquid fuel between the upstream injection location and the plurality of downstream injection locations based on a temperature parameter of the compressed intake air. The compressed intake air is combusted with the liquid fuel and a compression ignition pilot fuel in the plurality of combustion cylinders.
