Abstract
Official abstract text for this publication.
A system and method comprising four valves per cylinder of a multi-cylinder engine is provided to control cylinder intake and exhaust valves independently from other cylinders in response to engine operating conditions. The engine valve deactivation system for the engine may comprise two or more cylinders wherein each cylinder has two exhaust valves and two inlet valves. The system and method may allow for cylinder deactivation and/or high swirl to both be delivered.
First claim
Opening claim text (preview).
The invention claimed is: 1. An engine valve deactivation system for an engine comprising: two or more cylinders, each cylinder having two exhaust valves and two inlet valves, and at least one cylinder of the engine being deactivatable at a same time that a remaining set of the cylinders is normally operated, wherein each of the cylinders has one inlet valve selectively deactivated via a first supply of pressurized fluid, and wherein each deactivatable cylinder further has both…
