Patent ID: 7334557

Claim:
An engine lubrication system for an engine comprising a conventional first oil pump and a first oil filter, the system comprising: at least a second pump comprising a prelubrication pump in fluid communication with an engine so that upon initiation of engine ignition, said prelubrication pump supplies oil, for a predetermined time, to said engine ahead of that supplied by a conventional oil pump forming part of said engine; at least one supplemental oil filter assembly comprising a second oil filter in fluid communication with said engine and said prelubrication pump so that during operation of said engine a portion of said oil flowing therethrough is diverted to said supplemental oil filter assembly thereby providing enhanced purification of said oil; sensing means for monitoring operation of said engine lubrication system and generating signals indicative thereof; and a controller in communication with said prelubrication pump and said sensor for receiving said signals therefrom and issuing commands in response thereto, said controller further being in communication with an ignition switch operable to initiate ignition of said engine, and wherein upon said initiation of engine ignition said controller causes said prelubrication pump to operate.
