Abstract
A system and method for delivering lubrication oil to an internal combustion engine. The engine lubrication system () comprises a lubrication oil reservoir (), a pump () to deliver lubrication oil to the engine from the reservoir (), and a pressurization system () for pressurizing oil received by the pump from the reservoir for delivery to the engine. The pressurization establishes a positive pressure at the pump inlet to assist delivery of oil having entrained vapor cavities to the engine for lubrication thereof. The pump () comprises a solenoid actuated positive displacement pump, whereby operation of the pump may be selectively controlled by the manner in which the solenoid is operated. The engine lubrication system () further comprises a pressure release system () comprising pressure relief valve () for relieving excess fluid pressure within the oil reservoir ().
