Abstract:
1. A method for providing parallel filtration in an internal combustion engine, said engine having a lubricating oil, a normally provided spin-on oil filter whose inlet is hydraulically connected to a normally provided oil pump via a discharge tube and said normally provided spin-on oil filter whose outlet is hydraulically connected to a normally provided engine gallery via a normally provided filter stud, said method comprising the steps of: a. providing an adapter interposed between said engine and said normally provided spin-on oil filter for hydraulically connecting to said discharge tube and said engine gallery; b. providing a first hydraulic connection means to connect an upstream end of said first hydraulic connection means to said discharge tube via said adapter and to connect a downstream end of said first hydraulic connection means to an inlet of a high efficiency filter; c. providing a second hydraulic connection means to connect a downstream end of said second hydraulic connection means to said engine gallery via said adapter and to connect an upstream end of said second hydraulic connection means to an outlet of said high efficiency filter; d. providing an adapter injection nipple to affix said adapter to said engine and to provide a hydraulic connection through a plurality of injection orifices between said engine gallery and said second hydraulic connection means downstream end by threading said adapter injection nipple to said normally provided filter stud; and e. providing said adapter injection nipple whose functional architecture locates said injection orifices immediately contiguous to an area of high velocity lubricating oil from said spin-on oil filter outlet which is channeled fluidly unobstructed by and through said adapter injection nipple whereby a first effect, a Venturi or vacuum effect is established which in cooperation with a second effect, a differential pressure effect across said spin-on oil filter, furthered by a third effect, a fluid kinetic energy effect captured by said adapter fluidly connected to said discharge tube, said three effects promote the net result of lubricating oil flow through said high efficiency filter and into said engine gallery; whereby said high efficiency filter is connected in parallel to said normally provided spin-on oil filter quickly, without modifications, including no narrowing or obstructions of said adapter nipple conduit flow area, to said engine, and without removing any amount of said lubricating oil from said engine gallery.
