  • Patent number: 11448148
    Abstract: A method and system of power generating is provided to reduce a startup time of a genset for providing requested power to a utility grid or a load. The genset includes a generator, a turbocharger, and an energy storage. The generator includes an engine. The genset responds to a genset start signal by accelerating an engine speed of the generator to reach a synchronous speed. The engine speed is accelerated more rapidly by activating the energy storage device to supply power to at least one of the generator and the turbocharger. The generator then supplies power to the utility grid or load.

  • Patent number: 11441512
    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.
