Shutter valve system for internal combustion engines

Abstract

A valve system designed for use in an internal combustion engine to regulate the flow of working fluids including air/fuel mixtures and exhaust gases to and from a cylinder comprising an intake valve and an exhaust valve. At least one but preferably both of the intake and exhaust valves comprise a shutter valve, defined by a plurality of valve elements in the form of partially overlapping valve blades slidable relative to one another and defining a central aperture having an adjustable dimension dependent upon the relative positioning of the plurality of valve elements as they are selectively oriented between an open position and a closed position. The central aperture at least partially defines a free, unobstructed flow path of fluid passing into or out of the combustion chamber before and after the ignition of the air/fuel mixture. A control assembly comprises a plurality of sensors each transferring sensor signals to a central processing unit for purposes of indicating the operating characteristics of the internal combustion engine. The central processing unit is interconnected by an activation assembly to the intake and exhaust shutter valve so as to regulate operation thereof based on the operational conditions of the internal combustion.
