摘要： A pre-start lubricating system for reducing wear in internal combustion engines delivers lubricating oil into an engine oiling system at a pressure greater than the engine's normal operating oil pressure before the engine is cranked. The pre-start lubricating system involves the engine's vacuum, electrical and oiling system. The pre-start lubrication system has a pressure vessel of desired volume with a vacuum communicator and an oil communicator with a first aperture. A piston inside the pressure vessel between the oil communicator and the vacuum communicator defines an oil storage reservoir and a vacuum reservoir. Connected to the piston is a piston spring for biasing the piston against oil pressure and vacuum and for raising oil pressure in the oil reservoir after the engine has been shut down and the vacuum in the vacuum reservoir has dissipated. A valve for controlling oil flow between the oil storage reservoir and the engine oiling system has a moveable core and a biasing spring for moving the core toward the first aperture. An actuator operates the valve for releasing oil held under pressure in the oil storage reservoir and has an electrical solenoid for moving the core away form the first aperture, a switch for energizing the solenoid, and a timer. Finally, a thermal pressure relief device in the valve relieves excess pressure created by thermal expansion of oil in the oil storage reservoir.
