Abstract: Variable valve control method and apparatus for an internal combustion engine provided with a variable valve mechanism that varies an operating characteristic of an intake valve, for controlling a gas amount passing back through the intake valve by variably controlling the operating characteristic. A storage section stores previously a correlation between a value equivalent to an opening area of the intake valve and a valve passing gas amount, corresponding to predetermined effective cylinder capacity. A conversion section converts that value equivalent into the valve passing gas amount by referring to the correlation. A correction section corrects the value equivalent based on a ratio between the converted valve passing gas amount and a requested valve passing gas amount. A calculating section calculates requested effective cylinder capacity (by which the requested valve passing gas amount can be obtained based on the value equivalent to the opening area) based on the valve passing gas amount obtained by referring to the correlation based on the corrected value equivalent to the opening area, and the requested valve passing gas amount. A control section controls the variable valve mechanism according to the requested effective cylinder capacity calculated.

Abstract: The hydraulic play compensation device, having an outer cylinder part which is closed on one side by a base and in which a piston element which lies on its inside is guided so as to be longitudinally displaceable, with a guide gap, having an oil pressure space having an oil inlet which supplies the oil supply space, and having a connecting duct controlled by a nonreturn valve between the oil supply space and the oil pressure space. For optimized removal of air which is introduced via the oil inlet, it is proposed that a ventilation path which connects the oil supply space and the guide gap is formed in the piston element downstream of the oil inlet and upstream of the connecting duct.

Abstract: 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.

Abstract: 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.

Abstract: Constant pressure internal combustion engine having an elongated combustion chamber which in some embodiments is folded back upon itself and has a rough, twisting interior side wall, a fuel inlet for introducing fuel into the chamber, a compression chamber in communication with the combustion chamber, means for varying the volume of the compression chamber and combustion chamber to form a mixture of fuel and air that burns as it travels through the chamber and is further mixed by the rough, twisting side wall of the chamber, an expansion chamber in communication with the combustion chamber, and an output member in the expansion chamber which is driven by pressure produced by the burning mixture, with the means for varying the volume of the compression chamber and the output member in the expansion chamber being connected together for movement in concert such that the pressure remains substantially constant within the combustion chamber. A gas flow separator near the fuel inlet forms one or more smaller volumes within the combustion chamber where the fuel can mix and burn with only a portion of the air introduced into the chamber. Long, sharp protrusions extend inwardly from the wall of the combustion chamber and form hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber, and these protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air.
