ABSTRACT:
A lubricant reserve system (10) includes a reservoir tank (18) coupled to an accumulator T fitting (22). Additionally, coupled to the accumulator T fitting (22) is an accumulator pressure monitoring system (24) and an electronically-actuated valve (28). The reservoir tank (18) is adapted to hold a quantity of lubricant and a volume of gas having a gas pressure. The valve (28) opens in response to a control signal generated prior to ignition of an internal combustion engine (12) to prime the engine and closes when the engine (12) is disabled. The accumulator pressure monitoring system (24) is adapted to provide an indication of sufficient priming of the engine (12) prior to ignition of the engine (12). System (10) discharges lubricant (38) from the reservoir tank (18) while the engine (12) is running when the gas pressure is greater than a lubricant pressure of the engine lubrication system (13). Likewise, system (10) accumulates lubricant (38) in the reservoir tank (18) while the engine (12) is running and the gas pressure is less than the lubricant pressure of the engine lubrication system (13).
