    Abstract: A variable valve timing control device includes a rotational shaft, a rotation transmitting member assembled around the rotational shaft, and a vane assembled to one of the rotational shaft and the rotation transmitting member. The variable valve timing control device also includes a fluid pressure chamber defined between the rotational shaft and the rotation transmitting member and divided into a retarded angle chamber and an advanced angle chamber by the vane, a fluid passage through which an operation fluid is selectively supplied to or discharged from the advanced angle chamber or the retarded angle chamber, and a torsion coil spring for constantly biasing the rotational shaft to an advanced angle direction relative to the rotation transmitting member. The torsion coil spring is disposed between the rotational shaft and the rotation transmitting member under a condition that the torsion spring is compressed to a predetermined length from a free length.

    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.

    Abstract: A supply switching valve (140) can selectively switch the communication between a supply path (104) and a retard supply path (110) and the communication between the supply path (104) and an advance supply path (120). Check valves (111, 121) are arranged in the retard supply path (110) and the advance supply path (120), respectively. The check valves (111, 121) allow the working oil to be supplied from an oil pump (102) to each oil pressure chamber and prohibit the reverse flow of the working oil from each oil pressure chamber to the oil pump (102). A discharge switching valve (150) is configured independently of the supply switching valve (140) and can selectively switch the communication between a retard discharge path (130) and a discharge path (134) and the communication between an advance discharge path (132) and the discharge path (134).

    Abstract: A variable cam timing phaser for an internal combustion engine having at least one camshaft comprising a housing, a rotor, a spool valve, and a recirculation check valve. The housing and the rotor define at least one vane which separate chambers, advanced and retard. The spool valve comprises a spool having a plurality of lands mounted within a bore in the rotor. The spool is slidable from an advance position through a holding position to a retard position. The phaser also has an advance exhaust passage, a retard exhaust passage, and a return passage to route operating fluid to the chambers. The recirculation check valve is in the return passage and only allows flow of fluid from the advance chamber into the return passage when the spool is in the retard position and fluid from the retard chamber into the return passage when the spool is in the advance position.

    Abstract: A rocker arm is swingably supported by a control shaft that has an eccentric control cam formed thereon. The rocker arm is swung by a torque of a crankshaft of the engine. Two swing cams are swingably supported by a drive shaft and actuate respective engine valves to make an open/close operation of the same by receiving the swinging movement from the rocker arm. The rocker arm comprises a cylindrical base portion through which the control shaft passes; a first projected end that is provided at a first radially outside part of the cylindrical base portion in the vicinity of one axial end of the cylindrical base portion, the first projected end receiving the torque from the crankshaft for carrying out the pivotal movement of the rocker arm; and two second projected ends that are spaced from each other and provided at a second radially outside part of the cylindrical base portion, the second projected ends actuating the two swing cams when the rocker arm is swung. The first and second radially outside parts are opposite with respect to an axis of the cylindrical base portion.
