    Abstract: An apparatus or system includes a component that generates or transfers noise having a frequency within a noise frequency range. The component may include a boundary. The apparatus or system may be an engine in some examples. The engine may additionally include a micro-perforated sheet positioned a distance from the boundary. The micro-perforated sheet may include a plurality of micro-perforated holes, and may be configured to absorb sound within an absorption frequency range based on parameters of the micro-perforated sheet. The parameters may include the distance from the boundary and dimensions of the micro-perforated holes, and may be set such that the absorption frequency range overlaps the noise frequency range.

    Abstract: A fuel delivery system may be utilized in an internal combustion engine or a generator engine. The fuel delivery system includes a fuel injector and a venturi. The venturi provides a force for delivering the fuel into the manifold of the engine, and the fuel injector provides metering to control the amount of fuel delivered into the manifold of the engine. In one example, the fuel delivery system includes a first chamber configured to enclose a gaseous fuel, a second chamber configured to direct a flow of air through the venturi, and a plunger. The plunger is controlled to selectively connect and disconnect the first chamber and the second chamber to control the flow of the gaseous fuel into the second chamber under a differential pressure of the venturi.

    Abstract: An apparatus includes a controlled field alternator or utility source of electrical power, a conversion device, and a controller. The conversion device includes a first power input associated with a first power source, a second power input associated with a second power source, and circuitry configured to perform a first conversion of power from a first format from the first power source to a second format for charging the second power source and perform a second conversion of power from the second format for the second power source to a third format for supplying a load.

    Abstract: A power generation system that includes a generator comprising an alternator and an internal combustion engine configured to drive the alternator to generate power. The power generation system may provide power to one or more loads. The power generation system may further include an enclosure that houses the internal combustion and the alternator. The enclosure may include one or more openings and that permit air to flow into or out of the enclosure. The power generation system may include a mechanism that may regulate the flow of air through the openings in the enclosure. The mechanism may include a cover that may be positioned adjacent to the opening. The mechanism may control the position of the cover. The power generation system may further include a module that may monitor or measure a load of the power generation system and provide control to the mechanism.
