摘要： A system according to the principles of the present disclosure includes a timing control module and a diagnostic module. The timing control module controls engine valve timing by sending fluid to an advancing chamber of a cam phaser to adjust the cam phaser to an advanced position and by sending fluid to a retarding chamber of the cam phaser to adjust the cam phaser to a retarded position. The diagnostic module identifies a fault in a variable valve lift (VVL) mechanism based on a first difference between an advancing pressure of the advancing chamber and a retarding pressure of the retarding chamber.

摘要： A lubrication system for an internal combustion engine having a pressure increasing valve and a pressure regulator valve to optimize oil flow through an engine to increase engine efficiency. The lubrication system includes an engine driven oil pump connected to supply pressurized oil through a main oil feed to a main bearing gallery, a cam gallery, a cam phaser and switching valve lifters. The pressure increasing valve connected between the main bearing gallery and the cam gallery restricts oil flow to the cam gallery to raise oil pressure supplied to the cam phaser. The pressure regulator valve connected between the pressure increasing valve and the cam gallery to control oil pressure supplied to the switching lifters for cylinder deactivation or stepping valve train operation. The optimization of oil flow allows the engine to use a smaller oil pump and thereby increase engine efficiency while providing for actuation of the cam phaser or the switching lifters over the full engine speed range.

摘要： A lubrication system for an internal combustion engine having a pressure reducing valve to optimize oil flow through an engine to increase engine efficiency. The lubrication system includes an engine driven oil pump connected to supply pressurized oil through a main oil feed to a main bearing gallery, a cam gallery and a hydraulically actuated device such as a cam phaser or switching valve lifters. A pressure reducing valve connected between the main bearing feed restricts oil flow to the cam gallery to raise oil pressure supplied to the hydraulically actuated device. The increased oil pressure to the hydraulically actuated device allows the engine to use a smaller oil pump and thereby increase engine efficiency while providing for actuation of the cam phaser or the switching lifters over the full engine speed range.

The lubrication system includes an engine driven oil pump connected to supply pressurized oil through a main oil feed to a main bearing gallery, a cam gallery, a cam phaser and switching valve lifters. A pair of pressure increasing valves connected to the main bearing gallery and the cam gallery selectively restrict oil flow to the cam gallery and the main bearing gallery to raise oil pressure supplied to the cam phaser. A pressure regulator valve is connected to the cam gallery to control oil pressure supplied to the switching lifters for cylinder deactivation or stepping valve train operation. The optimization of oil flow allows the engine to use a smaller oil pump and thereby increase engine efficiency while providing for actuation of the cam phaser or the switching lifters over the full engine speed range.

摘要： A control module may include a cam phaser control module, a cam phaser oil pressure determination module, and a system oil pressure prediction module. The cam phaser control module may control an oil control valve (OCV) to control an oil flow to a cam phaser. The cam phaser oil pressure determination module may be in communication with the cam phaser control module and may determine a first engine oil pressure at a location between the OCV and the cam phaser when the OCV is in a open position. The system oil pressure prediction module may determine a second engine oil pressure at a location between the OCV and an oil pump outlet based on the first engine oil pressure.
