Ennine Systems DETROIT DIESEL Fig. 17 - Schematic Diagram of Typical 16V Lubrication System type oil filter may also be installed. The full-flow filter assembly can be remotely mounted or mounted on the engine as shown in Fig. 18. A by-pass valve, which opens at 15 psi (103 kPa), is located in the filter base to ensure engine lubrication in the event the filter should become plugged. filters a portion of the lubricating oil that is being bled off the oil gallery when the engine is running. Eventually all of the oil passes through the filter, filtering out minute foreign particles that may be present.
All of the oil supplied to the engine passes through the full-flow filter that removes the larger foreign particles without restricting the normal flow of oil. Some engines may be equipped with a by-pass filter assembly consisting of two filter elements, each enclosed in a shell which is mounted on a single base. An oil passage in the filter base connects the two The by-pass filter assembly, when used, continually annular spaces surrounding both filter elements. Page 24 (
