    Abstract: Apparatuses, methods, and systems for igniting fuel for an internal combustion engine, an ignition system include a first ignition device associated with a pre-combustion chamber of a cylinder and a second ignition device associated with a main combustion chamber of the cylinder. An engine control unit is operably connected to both the engine and the ignition system to ignite fuel for the cylinder with the first ignition device independently of igniting fuel with the second ignition device. The engine control unit determines an occurrence of a combustion condition and in response thereto (i) ignites fuel for combustion with both the first and the second ignition devices or (ii) ignites fuel for combustion only with the second ignition device. The engine control unit determines a second combustion condition and in response thereto ignites fuel only with the first ignition device.

    Abstract: The present disclosure provides an engine fueling system that includes multiple fueling valves such that the fuel transport delay can be reduced. The fueling system may also include an electrically driven compressor to improve engine properties during engine startup. For example, an engine fueling system comprising: a first compressor; an intake air throttle operably coupled to the first compressor and positioned downstream of the first compressor; a primary fuel path in communication with a fuel supply, wherein a first fuel from the fuel supply is injected into the primary fuel path upstream from the compressor; and a secondary fuel path in communication with the fuel supply, wherein a second fuel from the fuel supply is injected into the secondary fuel path downstream from the compressor.

    Abstract: A cooling system for a cylinder head of an internal combustion engine includes a cylindrical seat configured to engage an exhaust valve, a first coolant jacket, and a first conduit. The exhaust valve seat defines an annular cooling passage extending along a circumference of the cylindrical seat. A wall of the cylindrical seat defines a first opening into the annular cooling passage and a second opening into the annular cooling passage, where the first opening is positioned diametrically opposite to the second opening. The first coolant jacket is positioned adjacent to a fire-deck of the internal combustion engine. The first conduit fluidly couples the first coolant jacket to the at least one of the first opening and the second opening to the annular cooling passage in the exhaust valve seat.

    Abstract: A system and method for self-adjusting engine performance parameters in response to fuel quality variations that includes an exhaust sensor for measuring a level of carbon dioxide present in an exhaust manifold, at least one of a knock sensor and a cylinder pressure transducer for determining a location of peak pressure and a centroid, respectively, a controller in communication with the exhaust sensor and the at least one of the knock sensor and the cylinder pressure transducer, the controller correlating a methane number of the fuel used by the engine to a brake specific carbon dioxide value calculated using the level of carbon dioxide measured by the exhaust sensor and the at least one of the centroid and the location of peak pressure, and an adjusting mechanism, wherein the adjusting mechanism adjusts an engine performance parameter based on the determined methane number.
