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 control system for changing permanently and stepless valve timing in engines with internal combustion.The system is based on the fact that camshaft turns two times slower then the crankshaft.The system contains a double gear that is pivoting around the camshaft gear.The pinion gear is coupled with the camshaft gear.The driver gear is connected to the crankshaft gear through satellite gears, chain or belt. Pivoting the system around the camshaft gear can change valve timing in large limits.There are two different cassettes, the first one (FIG. 3, FIG. 3b and FIG. 4) is for pushrod engines and helps eliminate the inertia of the moving parts. Its movement is controlled by the accelerator pedal.The second cassette (FIG. 5 and FIG. 6) is designed for OHC (over head camshaft) engines and it must pivot around the camshafts moved by actuators under the control of the car computer.

摘要： In a valve timing adjusting device, a support section of a planetary carrier supporting a planetary rotator to enable sun-and-planet motion is located on an inner peripheral side of a first center, which is a tooth contact center between a first gear section of the first rotator and a third gear section of the planetary rotator, and is separate from an inner peripheral side of a second center, which is a tooth contact center between a second gear section of the second rotator and a fourth gear section of the planetary rotator. First moment generated in the planetary rotator by a radial load applied to the third gear section by the first gear section is larger than second moment generated in the planetary rotator by a radial load applied to the fourth gear section by the second gear section.

摘要： An actuator operation amount setting unit prepares the rotational speed command value for an electric motor such that the phase of an intake valve changes in accordance with the target phase. An electric-motor EDU controls the motor supply electric power such that the electric motor operates in accordance with the rotational speed command value. An overheating determination unit determines whether at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up based on a result of comparison between the information indicating the motor supply electric power and the reference value. A rotational speed command value restriction unit restricts the rotational speed command value provided to the electric-motor EDU to a value within a predetermined range, when it is determined that the at least one of the electric motor and the electric-motor EDU needs to be restricted from heating up. A reference value setting unit variably sets the reference value based on the rotational speed of the electric motor.
