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.

Abstract: Control of a spark ignited internal combustion in response to an exhaust manifold pressure measurement of an engine is disclosed. An engine out NOx amount for at least one cylinder is determined at least in part in response to the exhaust manifold pressure measurement and a brake mean effective pressure of the at least one cylinder. An operating condition of the engine is adjusted in response to the engine out NOx amount.

Abstract: An internal combustion engine, a method of operating the internal combustion engine, and a controller are disclosed. The method may comprise measuring a first pressure at a first position in a fluid line containing pressurized fluid; comparing the first pressure to a first threshold; in response to the first pressure exceeding the first threshold, transmitting a signal to depressurize the fluid line; after transmitting the signal to depressurize the fluid line, measuring a second pressure in the fluid line and comparing the second pressure to at least one of a second threshold and a third threshold, the second threshold being greater than the third threshold and less than the first threshold; and in response to the second pressure being less than the second threshold and exceeding the third threshold, transmitting another signal to depressurize the fluid line.
