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: A circuit for minimizing energy provided to a ground fault includes a source, a multiple switches, an output filter, and a controller. The switches include a first side pair of switches and a second side pair of switches configured to provide an output signal based on the source. The output filter includes one or more energy storage elements coupled to the first side pair of switches or the second side pair of switches. The controller is configured to receive a ground fault signal that indicates a fault has occurred and configured to generate a switch signal for the switches for a minimum energy state of the output filter and in response to the ground fault signal.

Abstract: An electric machine includes at least a printed circuit board and a magnetically permeable element. The printed circuit board includes a reluctance coil configured to generate a voltage in presence of a magnetic flux. The magnetically permeable element has a first end positioned adjacent to a rotor of the electrical machine and a second end positioned adjacent to the coil of the printed circuit board. In some examples, rotation of the rotor causes a change in the magnetic flux through the magnetically permeable element and generation of the voltage across the reluctance coil.
