Abstract (en)
[origin: WO9920875A1] An apparatus for automatically preventing wear in an internal combustion engine includes an electric pump (19), a disconnect coupling (26), a high arrestance filter (60), a programmable logic control element (36), and an external controller (44). The programmable logic control element is connected to a normally provided battery (42) 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 (12) 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 a radiator is discharged into the normally provided engine lubricating gallery (54). The external controller, such as a wireless remote control, is provided to activate the pump remotely upon demand.
