Abstract: A method for adjusting the rotational angle position of the camshaft (3) of a reciprocating piston internal combustion engine relative to the crankshaft (5) is provided. The crankshaft (5) is drivingly connected to the camshaft (3) via an adjusting drive (1), which is embodied as a triple-shaft gear mechanism, having a crankshaft-fixed drive shaft, a camshaft-fixed output shaft, and an adjustment shaft drivingly connected to an electric motor (4). A stop element is connected to the drive shaft and a counter-stop element is connected to the camshaft (3). The crankshaft rotational angle measuring signal and a position signal for the rotational angle of the adjusting shaft are detected during the starting step of the internal combustion engine. A phase angle signal for the position of the rotational angle of the camshaft (3), based on the initial position, in relation to the camshaft (3) is determined with the aid of the angle measuring signal, the position measuring signal and a gear variable of the triple shaft gear. After immobilization of the crankshaft (5) and the camshaft (3) in a reference position in relation to each other and after detection of the reference position, the phase angle in relation to the reference position is measured and is controlled to a target value signal.

Abstract: 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. In some embodiments, the combustion chamber is folded back upon itself and has a rough, twisting interior side wall, with long, sharp protrusions extending inwardly therefrom and forming hot spots which help to provide complete combustion of the fuel mixture throughout the combustion chamber. These protrusions, together with flow turbulators within the chamber, promote complete mixing and, hence, combustion of the fuel and air in the combustion chamber.

Abstract: When the engine speed is high (determination of YES at S100), actual intake valve phase is calculated based on rotation phase difference between rotation angles of crankshaft and camshaft, detected by using a crank angle signal and a cam angle signal, and actual valve timing is detected therefrom. When the engine speed is low (determination of NO at S100) and the crank angle signal and cam angle signal are unstable, an amount of change in camshaft rotation phase by the VVT mechanism in accordance with the operation amount of actuator detected by a motor rotation angle signal is calculated successively, and based on an accumulation of the amount of change, the actual intake valve phase is calculated, and the actual valve timing is detected.

Abstract: A method for determining a wear value of a transmission element between a crankshaft and a camshaft of a reciprocating piston internal combustion engine, in particular a timing chain or toothed belt, is provided. The camshaft is driven by the transmission element via a drive part, for example a camshaft gearwheel. In each case, at least one measurement value for the phase position of the drive part relative to the crankshaft is determined at time intervals during which the crankshaft drives the camshaft, and the wear value is determined from the difference between the measurement values.

Abstract: In an intake valve phase control after an engine stop command is issued, a stop-time phase is used as a target value. In the intake valve phase control, when the mode changeover condition is not satisfied, and an electric motor that serves as an actuator is not in a locked-state, the highest-speed mode, in which the amount of electric power supplied to the electric motor is fixed to the maximum value, is selected to reliably change the intake valve phase by a required amount. Then, the intake valve phase comes close to the stop-time phase and the mode changeover condition is satisfied, the control mode is changed from the highest-speed mode to the normal mode to set the control phase to the stop-time phase with higher accuracy, and the feedback control over the intake valve phase is executed.

Abstract: A variable valve timing control apparatus of an internal combustion engine has a drive rotary member rotated by an engine crankshaft, a driven rotary member fixedly connected to a camshaft and transferring a turning force from the drive rotary member to the camshaft, and a phase-change mechanism changing a relative rotational phase between the drive and driven rotary members and having an intermediate rotary member installed between the drive and driven rotary members for a relative rotational phase control. The variable valve timing control apparatus further has a holding mechanism and a releasing mechanism. The holding mechanism forces the intermediate rotary member and holds the relative rotational phase between the drive and driven rotary members, and the releasing mechanism releases a holding state of the holding mechanism.
