Oil flow control system for engine cylinder head |
摘要 |
A system for controlling a flow of pressurized oil in an internal combustion engine includes a cylinder head having a generally-flat external surface featuring a pressurized oil outlet and a pressurized oil inlet; and an oil flow control module including a generally-flat mating surface secured against the first surface of the cylinder head such that a first passage in the module places the outlet of the cylinder head in fluid communication with the inlet of the cylinder head. While the module's first passage minimally includes an oil restrictor, preferably, in a downstream portion thereof, the module preferably further includes a screen filter, and a spool valve operative to direct unrestricted oil flowing through the first passage into one of a plurality of fluid lines operatively connected to the cam phaser unit, whereupon the spool valve is used to variably advance or retard engine cam timing.
