摘要： A surface heater automatically adjusts the supply of fuel and/air to the burner in order to maintain a desired air/fuel ratio despite changes in ambient air temperature and/or pressure. The adjustment may be performed on a periodic or continuous basis and on either an open-loop basis or a closed-loop basis. The adjustment includes actuating one or more control devices that control the flow of air and/or fuel to the burner. If the adjustment is performed on a closed-loop basis, signals from a sensor can be used as feedback to control the flow of air and/or fuel into the burner to maintain a setpoint of a controlled parameter. The controlled parameter may include one or more of air mass flow rate, an intake O2 concentration, an exhaust O2 concentration, an exhaust gas composition, and an exhaust gas temperature.

摘要： 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.
