US 6,148,778 A · Air-fuel module adapted for an internal combustion engine

Abstract

A valve module that can be assembled to an internal combustion engine chamber. The valve module may have a first intake valve, a second intake valve, a third intake valve, a first exhaust valve and a second exhaust valve. The valves may be driven to an open position by hydraulically driven first pins. The exhaust valves may further have hydraulically driven second pins. The additional pins may increase the hydraulic forces which allow the exhaust valves to be opened even when there is a large pressure in the combustion chamber. The first pins of the exhaust valves may be controlled by a microprocessor controlled first control valve. The second pins may be controlled by a microprocessor controlled second control valve. The separate control valves and additional hydraulic force of the second pins may allow the microprocessor to open the exhaust valves at any point during a cycle of a combustion engine.
