Abstract
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.
