  • Patent number: 10060305
    Abstract: A control device has two modes as control modes of an electric power supply to an electromagnetic solenoid, which are used when a first determining unit determines that a difference between a sensed value of a phase and a target value of the phase exceeds a permissible range. One of the modes is a special mode that is used when a second determining unit determines that the sensed value of the phase reaches a threshold value. Another one of the modes is a normal mode that is used when the second determining unit determines that the sensed value of the phase does not reach the threshold value. In the special mode, the control device controls supply of the electric power to the electromagnetic solenoid in such a manner that an opening degree of an advancing port is larger than the opening degree of the advancing port in the normal mode.

  • Patent number: 10047642
    Abstract: The invention relates to an improved system of electro-mechanical hydraulic valve lifters for piston engine automobiles that increases fuel economy and reduces fuel emissions. The electro-mechanical hydraulic valve lifters enclose a magnetorheological fluid chamber, containing magnetorheological fluid. A control module manages voltage sent to the magnetorheological fluid in the magnetorheological fluid chamber. The control module introduces various amounts of magnetic flux to the magnetorheological fluid in the magnetorheological fluid chamber. The magnetorheological fluid's viscosity changes based on the amount of magnetic flux applied to it from the electromagnets and, along with the magnetorheological fluid chamber spring, controls how much an intake and exhaust port of the spark plug engine opens to control the amount of fuel used and exhaust let out of the engine.

  • Patent number: 10047643
    Abstract: When a variable valve timing device controls an oil pressure control valve in a manner that a VCT phase is locked at a middle lock phase, an advance chamber and a retard chamber are made to communicate with each other, so that oil is filled into both of the advance chamber and the retard chamber when the oil pressure control valve supplies oil to one of the advance chamber and the retard chamber in an oil filling mode. An oil pump supplies oil to the oil pressure control valve, and is controlled to have an oil flow rate that is equal to or larger than a predetermined value in the oil filling mode.

  • Patent number: 10006323
    Abstract: Disclosed are sliding cam actuators, methods for making and using such actuators, and motor vehicles with internal combustion engines employing sliding cam actuators. A sliding cam actuator is disclosed with two actuator pins projecting from an actuator housing. These pins move from retracted to extended positions and engage a shift barrel on a sliding camshaft. An actuator assembly moves each actuator pin to its extended position into engagement with the shift barrel to thereby slide the camshaft to a different location. An actuator shank is attached to the actuator housing and engaged with the actuator pins. Moving the first actuator pin to its extended position moves the actuator shank in one direction, which moves the second actuator pin towards its retracted position. Moving the second actuator pin to its extended position causes the actuator shank to move in another direction, which moves the first actuator pin towards its retracted position.

  • Patent number: 10006320
    Abstract: A system for controlling valve opening/closing timing that allows an unlocking operation to be reliably performed is configured. When extracting a lock member from a recess, a second control valve is set to an unlock position, a first control valve is set to a predetermined position, and a relative rotation phase is displaced. As a result, the relative rotation phase is displaced in a direction opposite to the direction of displacement by cam average torque from a camshaft. Afterward, by setting the first control valve to a neutral position, the relative rotation phase is displaced by the cam average torque, and when this displacement occurs, a state in which the lock member is separated from an inner wall of the recess is created, thus facilitating extraction of the lock member from the recess.
