Abstract

A fuel metering system for an internal combustion engine having a fuel injection timing unit to indicate a timepoint during one or more engine strokes, a fuel metering element have a predetermined full stroke volume for metering fuel into an air-fuel mixing location during one or more of the engine strokes, and a fuel metering element controller to control the delivery of fuel by causing the fuel metering element to deliver one of a full stroke volume and a fraction of a full stroke volume to achieve a desired AFR. In some embodiments, power generator circuitry is provided to harvest power from the ICE to power at least one of the fuel injection timing unit, the fuel metering element, and the fuel metering controller.
