ABSTRACT:
An apparatus for automatically preventing wear in an internal combustion engine includes an electric pump, a disconnect coupling, a high arrestance filter, a programmable logic control element, an electric fan assisted radiator, an external controller. The programmable logic control element is connected to a normally provided battery and automatically switches control power from the battery to the electric pump according to a programmed control operating cycle program, and is operatively independent of ignition switch activation or operator action. The inlet of the electric pump is connected to the normally provided engine oil sump for removing lubricating fluid. The lubricating fluid is pumped through the high arrestance filter, yielding a substantially contaminant free lubricating fluid which after flowing through the radiator is discharged into the normally provided engine lubricating gallery. The external controller, such as a wireless remote control, is provided to activate the pump remotely upon demand. The disconnect coupling is provided to facilitate evacuation of the oil sump for the purpose of an oil change by overriding automatic operation of the electric pump by a local control switch. In a second embodiment the inlet of the electric pump is dimensioned to be affixed and fluidly connected to the oil sump, and the radiator is eliminated. In another embodiment the inlet of the pump is connected to a hollow tube dimensioned for insertion into the dipstick well to gain access to the oil in the sump. Yet another embodiment, a pump assembly dimensioned as the normally provided oil filter replaces the filter, and it encloses in its volume the programmable control element connected to the electric pump whose inlet is connected to the oil sump, with the pump outlet connected to the oil gallery, and further including a transverse oil filter cartridge to provide for filtration during normal engine operation.
