ABSTRACT:
An internal combustion engine valve actuating device located directly above each cylinder which has a co-axial venturi shaped duct (20) that is removably attached with threaded capscrews (24) and sealed with an o-ring (28). The interior of the duct contains a number of inwardly facing vanes (30) that hold an electromechanical valve actuator (48) complete with an engine intake valve (50). When a pulsed electrical signal is received by the actuator, opposed electromagnetic fields are developed reciprocating the valve. A fuel injection system introduces combustible fuel into the duct at the trailing edge of the vanes. The valve actuating device may also be applied to the exhaust system, less the fuel injection, and the valve actuator may be cooled by interconnecting cavities (60) within the vanes using engine coolant or oil.
