Abstract: A motor drive device for valve timing control of an internal combustion engine includes: a motor drive unit that controls a phase of a camshaft to drive a motor for controlling opening and closing operation of a valve; and a determination unit that determines whether a timing is to start up the motor or to normally drive the motor. The motor drive unit drives the motor with an advance angle when it is determined that the timing is to normally drive the motor by the determination unit, and the motor drive unit normally drives the motor without the advance angle when it is determined that the timing is to start up the motor.

Abstract: A modified rocker assembly having an offset end is designed for engine heads having an obstruction preventing use of a symmetric switching rocker arm. The modified rocker assembly has an obstructed side and a non-obstructed side and has an outer structure with a first end, and an inner rocker structure fitting within the outer structure, the inner structure also having a first end. The modified rocker assembly has an axle pivotally connecting the first ends of inner structure to the outer structure, such that the inner structure pivots within the outer structure around the axle. At least one torsion spring on one side of the axle rotationally biases the inner structure relative to the outer structure. The outer structure is offset on the obstructed side as it extends from the second end toward the first end, creating the first offset portion to provide additional clearance on the obstructed side.

Abstract: Embodiments of the disclosure provide variable valve timing (VVT) mechanisms. A VVT mechanism according to the disclosure can include: a lever having a first end, a second end, and a fulcrum positioned therebetween; a length-adjustable push rod coupled to the first end of the lever and including an actuator therein; a rod valve coupled to the second end of the lever, the rod valve being configured to open and close an intake valve of an engine system based on a movement of the lever; and an engine control unit (ECU) operatively connected to the actuator of the length-adjustable push rod, wherein the ECU adjusts a length of the length-adjustable push rod based on an operating condition of the engine system. In addition or alternatively, the ECU can control an amount of cushioning fluid for the valves to affect the rate at which the intake valve opens or closes.

Abstract: A motor control apparatus for adjusting a cam phase includes a motor control part, which controls a current supplied to a stator coil by controlling plural switching elements forming an inverter to turn on and off. The motor control part stops the current supplied to the stator coil each time a motor rotates a predetermined rotation angle interval in a power generation control mode, in which a rotation torque is generated in a direction to impede the motor rotation. The motor control part maintains the power generation control mode when a rotation signal is determined as varying in a predetermined time period. The motor control part switches over an operation mode to a normal control mode to generate a rotation torque in a direction to promote the motor rotation when the rotation signal is determined as not varying in the predetermined time period.

Abstract: Disclosed is a control and monitoring method via H bridge of an electromagnet including a solenoid through which a current can be passed in one direction and in the opposite direction. The solenoid delivers a signal corresponding to a mechanical locking movement. Once a current flows in the solenoid, the bridge switches automatically into high impedance with all transistors thereof blocked. A measurement is then taken at the terminals of the solenoid to verify the locked state of the electromechanical system.

Abstract: A method for automatically controlling an internal combustion engine, in which an axial displacement (s(t)) and an angle of rotation (w(t)) of a gas-exchange valve are measured during a valve stroke. A displacement deviation is computed from the displacement (s(t)) relative to a reference valve, and an angle of rotation deviation is computed from an initial value and an end value of the angle or rotation. The further operation of the internal combustion engine is set on the basis of the displacement deviation and the angle of rotation deviation.
