Abstract: Methods and systems for sensing a fluid level associated with an engine are described. The method comprises generating an input signal and applying the input signal to a resistive portion and a capacitive portion of a fluid level sensing device, measuring a first varying output of the resistive portion of the fluid level sensing device through a first channel of a controller of the engine, measuring a second varying output of the capacitive portion of the fluid level sensing device through a second channel of the controller of the engine, and translating at least one of the first varying output and the second varying output into a level of fluid and outputting the level of fluid.

Abstract: A lubrication system for a machine such as a mobile generator, a mobile light tower, or a mobile jobsite heater implements an engine oil supplementation strategy from an auxiliary sump to increase service time between engine oil servicing tasks of an internal combustion engine. The system periodically introduces a supplemental volume of oil from an auxiliary sump into the engine's lubricating system during an oil supplement event. The fluid communication between the engine sump and auxiliary sump may be achieved through multiple sump connections, which may include a sump-to-sump return line that provides a liquid connection allowing oil to freely flow between the engine sump and the auxiliary sump and a vent line that provides a gaseous connection between a void space at an upper end of the auxiliary sump and a void space at an upper end of the engine sump.

Abstract: A filter cartridge includes a shell, a connecting ring, an end cap, and an axially directed sealing member. The shell defines an inner cavity and an upper lip disposed along an upper edge of the inner cavity. The upper lip defines a channel. The connecting ring is positioned outside of the inner cavity and is engaged with the channel. The connecting ring includes a threaded region extending along a central axis of the shell. The end cap is engaged with the shell adjacent to the upper lip. The axially directed sealing member is positioned between the shell and the end cap and extends axially outward so as to form an axial seal with a filter head when the filter cartridge is installed on the filter head.
