ABSTRACT:
A primary pump system for lubricating an internal combustion engine includes a pump constructed and arranged to pump lubricant to an engine prior to engine cranking and continuously during operation of the engine. A variable speed electric motor is constructed and arranged to drive the pump independently of engine speed. A controller controls operation of the motor and thus the operation of the pump. An engine load sensor senses a load on the engine. The controller is responsive to a signal received from the engine load sensor to control the motor so that the pump may supply lubricant to the engine in accordance with engine load.
