摘要： The invention provides a valvetrain configuration in an internal combustion engine in which a plurality of two-step rockers enable the engine poppet valves to switch between two lift profiles. In addition, a lost-motion stationary lash adjuster enables the deactivation of the engine poppet valve. The integration of a two-step rocker with a deactivating stationary lash adjuster yields a better control of the combustion process, under different engine operating conditions than what is achievable with either one of these actuators acting alone. Preferably, the locking and unlocking of the two-step rocker arm and deactivating stationary lash adjuster is controlled by two on/off hydraulic valves in a hydraulic circuit, and a piloted check valve prevents hard landings between stationary and moving components within the stationary hydraulic lash adjuster.

摘要： A single hydraulic circuit module is provided for controlling valve lift at multiple cylinders in an engine. The single module includes a housing that at least partially forms a supply passage and a control passage. The supply passage is in fluid communication with the fluid supply and the control passage is in fluid communication with the feed passage. At least one solenoid valve is provided and supported by the housing positioned between the supply passage and the control passage. The solenoid valve is controllable to vary fluid flow from the supply passage to the control passage to permit adjustment of hydraulic lift assemblies to vary lift of engine valves in response to control of the solenoid valve.

摘要： The apparatus of the present invention provides a lash adjuster feed channel for an engine assembly. The engine assembly includes first and second sets of hydraulic lash adjusters responsive to a variation in hydraulic fluid pressure to cause a variation in lift of first and second sets of engine valves respectively operatively connected thereto. The cylinder head defines a first feed passage in fluid communication with the first set of hydraulic lash adjusters, and a second feed passage in fluid communication with the second set of hydraulic lash adjusters. The valve lift of the first set of engine valves is independently variable by controlling the transfer of hydraulic pressure in the first feed passage, and the valve lift of the second set of engine valves is independently variable by controlling the transfer of hydraulic pressure in the second feed passage. A corresponding method is also provided.

摘要： An internal combustion engine includes hydraulically-controlled cylinder deactivation and has an engine block with a plurality of cylinders formed therein. At least one-half of the cylinders are deactivatable by collapsible lifters. An individual hydraulic circuit module is positioned adjacent each deactivatable cylinder. Each hydraulic circuit module includes a valve and is configured to receive a supply of oil from the engine block and to selectively provide pressurized oil to the respective collapsible lifters for cylinder deactivation. A solid cover plate is positioned adjacent each cylinder which is not deactivatable.
