Transition Control For Multiple Displacement Engine

Assignee:
DaimlerChrysler Corporation - Auburn Hills MI
International Classification:
F02B 77/00
US Classification:
123198F
Abstract:
A process for enabling cylinder deactivation in a multiple displacement engine involving oil aeration includes detecting engine speed. Once the engine speed has been determined, a delay period is established prior to enabling cylinder deactivation. The delay period is a function of whether engine speed exceeds a preselected threshold and an amount by which the threshold is exceeded. When the delay period expires, a request is generated for cylinder deactivation.

A cylinder deactivation arrangement for an engine is provided. The arrangement includes an engine with main oiling circuit passages and lifter oil gallery control circuit passages formed internal to a cylinder block of the engine. The lifter oil gallery control circuit is arranged so as to provide an oil flow path internal to the cylinder block from the main oiling circuit to the deactivating lifter. A lifter is positioned in the cylinder block and arranged in fluid communication with the lifter oil gallery control circuit. A control valve is positioned in the cylinder block and arranged in fluid communication with the main oiling circuit and the lifter oil gallery control circuit. The control valve is arranged to allow selective fluid communication of oil from the main oiling circuit to the lifter oil gallery control circuit to selectively control actuation of the lifter.
Method And Code For Controlling Actuator Responsive To Oil Pressure Using Oil Viscosity Measure

International Classification:
G01M 19/00
US Classification:
731181, 73116, 731172, 731173
Abstract:
A method and code for controlling the operation of a deactivatable valve lifter of an internal combustion engine includes determining an oil viscosity measure based upon an engine oil pressure achieved when the engine is operating at a warm engine idle operating condition; determining a minimum oil temperature for actuator operation based on a comparison of the oil viscosity measure with a stored value representing the oil's nominal viscosity; and enabling actuator operation when an instantaneous oil temperature is not less than the minimum oil temperature.

US Classification:
123 9039, 123 9036, 123 9044, 123 9016
Abstract:
A rocker shaft arrangement for a valvetrain system of an engine is provided. The rocker shaft arrangement includes a split rocker shaft having two fluidly separate internal regions. Each of the fluidly separate internal regions is arranged to selectively carry an independent supply of pressurized oil for distribution to valvetrain components. The two fluidly separate regions of the split rocker shaft are each further arranged to supply pressurized oil independent of each other to one of a high lift rocker arm and a low lift rocker arm of a rocker arm assembly for an engine valvetrain system.

123 9039, 123 9016, 123 9044, 74559
Abstract:
A variable lift deactivateable valvetrain system for an engine is provided. The system includes a camshaft, a rocker shaft, a valve and at least one rocker arm rotateably connected to the rocker shaft and arranged to engage the camshaft. A connecting rocker arm is rotateably connected to the rocker shaft and is in constant engagement with the valve. The connecting rocker arm is arranged to operate in selective engagement with the at least one rocker arm to provide a variable lift deactivateable valvetrain configuration. The system further includes a low lift rocker arm having a low lift pin assembly and a high lift rocker arm having a high lift pin assembly. The low and high lift pin assemblies are arranged to selectively engage the connecting rocker arm responsive to oil pressure selectively directed to the low and high lift pin assemblies.
The present invention is a shaft-mounted rocker arm arrangement for an internal combustion engine which provides simplified assembly and disassembly by allowing individual rocker arms to be added or removed separately and without removing the rocker shaft. The present invention utilizes a rocker shaft and a rocker arm rotatably coupled to the rocker shaft. The rocker shaft includes a flat portion arranged to receive the rocker arm. The rocker arm includes a body portion and a curved arm portion arranged to match a curvature of the rocker shaft, and arranged to engage more than 180 degrees of the rocker shaft.

International Classification:
F01L001/34 F01L001/14
US Classification:
123/090550, 123/090480
Abstract:
A valve lifter for an internal combustion engine comprises an outer body, an inner body and at least one pin. The inner body is movable with respect to the outer body, and the at least one pin is movable in response to hydraulic pressure into the groove to lock the outer body against movement relative to the inner body.
Cylinder Head Cover Module With Integrated Valve Train

International Classification:
F01L 1/00 F01L 9/02
US Classification:
123 9012, 123 901
Abstract:
An internal combustion engine includes a cylinder block, a cylinder head and a cylinder head cover module attached to the cylinder head. The cylinder head cover module includes passageways and a plurality of receiving features for valve train components. A housing may be integrally formed with the cylinder head cover module. The cylinder head cover module may include components of a non-integrated valve control system and may be used in either an inline or a V-shaped engine.
