摘要： An engine has an auxiliary cylinder 2 and a valve body 6 slidable in this cylinder. The valve body 6 has a gas space 7 formed in it. The engine further has an actuator for shifting the valve body 6 to switch the communication between the main combustion chamber and the gas space 7 and the isolation of the chamber and cavity from each other. The slidable valve may function as a compression ratio changer, which switches the communication and the isolation according to the load on the piston. In this case, the engine has a third compression ring 18. The slidable valve may also function as a suction or exhaust valve, which switches the communication between the combustion chamber and auxiliary passage and the isolation of the chamber and passage from each other during the suction or exhaust strokes. This improves the suction or exhaust efficiency of the engine.

摘要： Rotary valve system for controlling communication with a port in an internal combustion engine which, in one disclosed embodiment, has a crankshaft, compression and expansion pistons connected to the crankshaft for reciprocating movement within compression and expansion chambers, a combustion chamber in which air from the compression chamber is combined with fuel and burned to produce an increased gas volume. The valve system has an outer valve member which is rotatively mounted in a bore and has an opening which moves into and out of communication with the port as the outer valve member rotates, an inner valve member rotatably mounted within the outer valve member with an opening at least partly overlapping the opening in the outer valve member, a flange extending along one edge of the opening in the inner valve member and through the opening in the outer valve member for sealing engagement with the wall of the bore, and means for effecting rotation of the valve members to change the degree of overlap between the openings and thereby control the timing and duration of communication between the openings and the port.

摘要： Internal combustion engine and method with compression and expansion chambers of variable volume, a combustion chamber, a variable intake valve for controlling air intake to the compression chamber, a variable outlet valve for controlling communication between the compression chamber and the combustion chamber, means for introducing fuel into the combustion chamber to form a mixture of fuel and air which burns and expands in the combustion chamber, a variable inlet valve for controlling communication between the combustion chamber and the expansion chamber, a variable exhaust valve for controlling exhaust flow from the expansion chamber, means for monitoring temperature and pressure conditions, and a computer responsive to the temperature and pressure conditions for controlling opening and closing of the valves and introduction of fuel into to the combustion chamber to optimize engine efficiency over a wide range of engine load conditions. The relative volumes of the compression and expansion chambers and the timing of the valves are such that the pressure in the combustion chamber remains substantially constant throughout the operating cycle of the engine, and exhaust pressures are very close to atmospheric pressure regardless of the load on the engine. The engine runs so quietly and burns so cleanly that in some applications it may not require a muffler and/or a catalytic converter.

摘要： A piston-cylinder device, such as a Rankine cycle engine, is provided with one or more variable displacement cylinders and variable stroke pistons for accommodating loads of variable torque. Cylinder displacement is varied by a movable cylinder head internally of the cylinder and auxiliary to a fixed cylinder head, and piston stroke is varied by a variably fulcrumed lever linking piston connecting rods with a crankshaft. For the engine particularly, load torques are continually sensed and cylinder displacement adjusted accordingly. In turn, the position of the movable cylinder head is continually sensed, and the lever fulcrum adjusted accordingly.

摘要： Constant pressure internal combustion engine having compression and expansion chambers of variable volume, an elongated combustion chamber of substantially constant volume between the compression and expansion chambers, and a fuel inlet for introducing fuel into the combustion chamber where it mixes with compressed air from the compression chamber to form a mixture of fuel and air that burns as it travels through the combustion chamber. The pressure remains substantially constant within the combustion chamber over a wide range of operating and load conditions.
