  • Adaptive lubrication oil system
    Patent number: 5180034
    Abstract: An adaptive oil lubrication system for a marine propulsion system having a variable speed oil pump controlled by a microprocessor. The speed of the pump and, thus, the oil flow rate is varied to track the demand for lubrication by the propulsion system. A microprocessor monitors the propulsion system and calculates the appropriate speed of the oil pump to generate the oil flow needed by the propulsion system.
