摘要： The reciprocating valve actuation and control system includes a poppet valve moveable between a first and second position; a source of pressurized hydraulic fluid; a hydraulic actuator including an actuator piston coupled to the poppet valve and reciprocating between a first and second position responsive to flow of the pressurized hydraulic fluid to the hydraulic actuator; an electrically operated valve controlling flow of the pressurized hydraulic fluid to the actuator; and an engine computer that generates electrical pulses to control the electrically operated valve. The electrically operated valve preferably comprises a three path rotary latched magnetic motor actuating a rotary valve portion having a housing, a rotor, and a stator receiving and supplying hydraulic fluid pressure to the rotor, which alternately directs the hydraulic fluid pressure to the valve cylinder for opening of the valve, or to return to the engine oil sump, for closing the valve. In a presently preferred embodiment, the hydraulic actuator comprises a self-contained cartridge assembly including an actuator piston with dampers for damping motion of the actuator piston, limiting the actuator stroke to assure soft seating of the actuator, and to avoid overshoot during the engine valve opening stroke and the engine valve return stroke. The electro-hydraulic valves are electrically controlled by the engine computer, which generates electrical signals carried to the electro-hydraulic valves. The engine computer typically senses conventional engine variables, and optimizes performance of the valve actuation and control system according to preestablished guidelines, with information being supplied to the engine computer by sensors. The engine computer controls all aspects of engine performance, interfaces with all of the peripheral sensors, and calculates fuel parameters, ignition timing and engine valve timing based upon prior mapping of the engine. In this manner the engine can be controlled so as to provide maximum fuel economy, minimum emissions, maximum engine torque, or a compromise between these parameters.

摘要： A separate metering and metering unit for a diesel and/or propane or similar gas/liquid fuel powered internal combustion engine such as a dual fueled engine incorporates an intake filter, a lockout solenoid, and a metering device into a single integrated unit remote of the carburetor of the engine. The metering unit includes a heater immediately adjacent to the output of the injector metering device in order to provide heat necessary to prevent any freezing of the unit injector or gaseous fuel or oxidizers downstream of the metering unit. The injection of the propane allows for correct operation of a catalytic converter.

The electrically operated valve includes a linear latching motor, which includes a solenoid coil associated with a permanent magnet, wherein the coil is energized to create a central axial repelling magnetic field relative to the permanent magnet field, and to generate concentric repelling and attractive fields to produce secondary repelling and tertiary attractive forces on the permanent magnet.

摘要： 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.
