Method for operating an oil control valve

摘要

A method for operating an oil control valve in an internal combustion engine is provided. The oil control valve controls a camshaft phaser disposed at an output side of the control valve and includes a spool disposed in a spool housing. The camshaft phaser controls the phase relationship between a crankshaft of the internal combustion engine and a camshaft of the internal combustion engine. The method includes positioning the spool within the spool housing to substantially block oil flow between the camshaft phaser and the internal combustion engine when the engine is temporarily not running.
