Abstract: An engine for a marine drive has a combustion chamber. An engine body of the engine defines intake and exhaust ports communicating with the combustion chamber. An air induction system communicates with the combustion chamber through intake ports. An exhaust system communicates with the combustion chamber through the exhaust ports. Intake valves move between an opening position and a closing position of the intake ports. Exhaust valves move between an opening position and a closing position of the exhaust ports. Camshafts actuate the intake and the exhaust valves. A hydraulic VVT mechanism changes an actuating timing of the camshaft at which the camshaft actuates the intake valves or the exhaust valves. An ECU controls the VVT mechanism based upon a control characteristic. A temperature sensor, such as an oil temperature sensor, a water temperature sensor and an engine body temperature sensor, senses a temperature of oil of the VVT or a temperature relating to the temperature of the oil and sends a temperature signal to the ECU. The ECU adjusts the control characteristic when the temperature is lower than a preset temperature.

Abstract: An internal combustion engine has a camshaft whose phase can be adjusted with respect to a crankshaft by means of a setting mechanism. Also provided are a crankshaft sensor which senses the crankshaft angle and a camshaft sensor which senses the camshaft angle. The method comprises the following steps: A reference value for the phase is adapted in a predefined position of the setting mechanism when a predefined condition is satisfied. A measurement value for the phase is determined depending on the sensed crankshaft angle and camshaft angle. A corrected measurement value for the phase is determined depending on the reference value and the measurement value for the phase. A control signal for controlling the internal combustion engine is determined depending on the corrected measurement value.

Abstract: A device for varying valve timing in an internal combustion engine comprises an adjusting mechanism for varying an angle of rotation between a drive pinion (2) and a camshaft (end portion of the camshaft 1), said adjusting mechanism being configured as a wobble transmission. The drive pinion (2) comprises a first front-end gearing (9) and a disk (10) comprises a second front-end gearing (11), which first and second front-end gearings mesh partially with each other, and the number of teeth of said front-end gearings differ from each other by at least one tooth. To reduce the overall dimensions of the device and avoid gearing lash, it is proposed, on the one hand, to connect the disk (10) rotationally fast to the camshaft (1) and on the other hand, to configure the disk (10) in axial direction of the camshaft (1) as a flexible element that can be deformed in axial direction by an adjusting device (thrust plate 17).

Abstract: A rotor-locking mechanism for a vane-type camshaft phaser. A locking pin is disposed in the rotor and is permitted to travel into a well in either the rear cover or the front cover of the phaser. The pin is urged into the well by a return spring, and the end of the pin end is exposed to oil pressure for unlocking the pin. A first channel is provided between the advance-oil feed and the end of the pin, and a second channel is provided between the retard-oil feed and the end of the pin. The channels may be formed in either of the covers. The pin is unlocked whenever a predetermined oil pressure is exceeded in either the advance or retard oil feeds, permitting the pin to be unlocked through most modes of engine operation and to be locked only under specific predetermined low-pressure conditions, such as during engine starting.

Abstract: A device for electrically adjusting the relative rotation of two shafts, particularly a camshaft (15) in relation to a crankshaft of an internal combustion engine is provided. The adjusting device includes an adjusting gear system which is embodied as a triple-shaft gear mechanism and is provided with a crankshaft-fixed input part, a camshaft-fixed output part, and an adjusting shaft (13) that is connected in a torsion-proof manner to an electric adjusting motor shaft (32) of an electric adjusting motor (3). The adjusting motor (3) is configured as a brushless DC motor having a housing-fixed stator (35) and a permanent magnet rotor (34). A high degree of adjustment accuracy and adjustment speed are provided with minimal space requirements and low power consumption. This is achieved through the use of a double eccentric gear mechanism (2) and a double planetary gear mechanism, which are provided with a speed reduction of up to about 1:250 and low friction, as an adjusting gear system while using a highly inductive permanent magnet rotor for the adjusting motor (3).

Abstract: An engine for a marine drive has a combustion chamber. An engine body of the engine defines an air intake port communicating with the combustion chamber. An air induction device communicates with the air intake port to introduce air to the combustion chamber through the air intake port. The air induction device includes a throttle valve to regulate an amount of the air. An air intake valve moves between an opening position and a closing position of the intake port. A camshaft actuates the intake valve. A VVT mechanism changes an actuating timing of the camshaft at which the camshaft actuates the intake valve. A control device controls the change mechanism. A throttle position sensor, an intake pressure or other sensors sends respective signals to the control device. The control device determines a sudden acceleration state of the engine based upon at least one of the signals. The control device triggers the VVT mechanism to advance the actuating timing based only upon the throttle opening degree signal when the control device determines the sudden acceleration state.

The first rotor has a plurality of teeth for engaging the engaging sections of an elongate drive structure, and the second rotor has a plurality of teeth for engaging the engaging section of the elongate drive structure. A rotary load assembly is coupled to the second rotor. The elongate drive structure engages about the first and second rotors. The first rotor is arranged to drive the elongate drive structure and the second rotor is arranged to be driven by the elongate drive structure. One of the rotors has a non-circular profile having at least two protruding portions alternating with receding portions. The rotary load assembly is such as to present a periodic fluctuating load torque when driven in rotation, in which the angular positions of the protruding and receding portions of the non-circular profile relative to the angular position of the second rotor, and the magnitude of the eccentricity of the non-circular profile, are such that the non-circular profile applies to the second rotor an opposing fluctuating corrective torque which reduces or substantially cancels the fluctuating load torque of the rotary load assembly.
