Abstract
An oil flow control valve (10) in a combustion engine is operated for affecting a cam phaser (26) disposed at an output side of said oil flow control valve (10). The cam phaser includes a spool (14) disposed in a spool housing (12). The method for operating the valve includes synchronising a displacement of said spool (14) in said housing (12) with combustion demands, and synchronising movement of said spool (14) with oil pressure characteristics on the output side of the oil flow control valve (10).
Claims10
A method for operating an oil flow control valve in a combustion engine, said oil flow control valve being provided for affecting a cam phaser disposed at an output side of said oil flow control valve and comprising a spool disposed in a spool housing, said method comprising the step of
- synchronising a displacement of said spool in said housing with combustion demands, and
- synchronising movement of said spool with oil pressure characteristics on the output side of the oil flow control valve.
An apparatus for controlling an oil flow control valve in a combustion engine, said oil flow control valve having an output side and being provided for affecting a cam phaser disposed at an output side of said oil flow control valve and comprising a spool disposed in a spool housing said apparatus comprising
- means for synchronising a displacement of said spool in said housing with combustion demands, and
- means for synchronising movement of said spool with oil pressure characteristics on the output side of the oil flow control valve.
