Abstract: An electromechanical valve actuator having a beginning of stroke damper to damp the impact between the armature stem and the valve stem as the valve is opened. The beginning of stroke damper includes an armature stem defining a stem passage and a valve stem including a lash compensator defining a cavity communicating with the stem passage. An oil pocket may be provided within the cavity to absorb the impact of the armature stem before the armature stem contacts the valve stem as the valve is opened. The lash compensator is configured so that the cavity has a discharge rate sufficient to ensure that the cavity completely drains at approximately the time the engine valve reaches the full open position.

Abstract: This invention is an efficient free-piston internal-combustion engine having an expansion ratio greater than the compression ratio and preferably with gas bearings supporting the piston. The use of gas bearings in combination with high-temperature ceramic materials allows the engine to be nearly adiabatic and with exhaust temperatures in excess of 600.degree. C. These high exhaust temperatures in turn allow the engine to operate as a topping cycle for gas turbines, Stirling engines, steam engines, etc. An improved valving system for flexible control of the engine may include the use of a valve actuator in a piston. In one embodiment, a pair of oppositely disposed combustion chamber passageways extending between the combustion chamber and the earth's atmosphere, each have a combustion-chamber valve for controlling the passage of gas through the passageways. The combustion-chamber valves are essentially simultaneously opened and closed to permit independent variation and control of the compression ratio, expansion ratio, and stroke of the engine. When the valves are opened, the combustion chamber is purged or supercharged with combustion supporting air, and closed to initiate compression. Variable control of the piston positions at which the valves are opened and closed permits the engine to operate at a high efficiency over a broad range of power output loading conditions. In another embodiment the combustion chamber and a gas compressor are combined in the same cylinder.

Abstract: An intake and exhaust system for use with lean-burn combustion engines includes a first intake port and a second intake port that transfer a fuel-air mixture to a combustion chamber within a cylinder. At least one exhaust port allows combustion gases to exit the combustion chamber. Preferably, in the intake and exhaust system, a first exhaust port and a second exhaust port are located on diagonally opposite sides of the cylinder. The first intake port preferably transfers a fuel-air mixture to the combustion chamber in a direction opposite of the second intake port. When two exhaust ports are used, it is preferable that the first exhaust port transfers gas outside of the combustion chamber in a direction opposite of the second exhaust port. The location of the input and exhaust ports creates a strong swirl under a range of loads.
