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.
