  • Systems and methods for providing compression release with continuous variable valve lift
    Patent number: 11473459
    Abstract: Methods and systems are provided for providing compression release during a stop/start event in an engine. In one example, a method includes: responsive to a request for a stop/start event in an engine with a continuously variable valve lift (CVVL) system including a compression release hydraulic valve actuator coupled to a valve of a first cylinder, determining a desired stop position of the engine; and prior to restarting the engine during the stop/start event, adjusting the compression release hydraulic valve actuator to open the valve during a compression stroke of the first cylinder. In this way, an amount of torque used to restart the engine may be reduced.

  • Electric variable cam timing control device
    Patent number: 11421564
    Abstract: When an EDU determines that a motor is in a control unstable state where the motor cannot be controlled to a target rotation speed due to a drive voltage output duty value being smaller than a threshold value, the EDU performs a control point shifting operation to shift a control point between a first control point, which is in the control unstable state, and a second control point, which is a control stable state outside the control unstable state. Thus, even when the motor is in a stepping rotation state, it is possible to control the target rotation speed regardless of influence of a cogging torque, and appropriately control the cam phase of the intake camshaft to a target phase when the engine is stopped.

  • Multiport rotary valve for piston engines
    Patent number: 11415027
    Abstract: A multi-port rotary valve has penetrations in the form of annulus sectors through its stationary outer shell and through its rotating inner core, with the penetrations being situated so that, once during each rotation of the core, each core penetration overlaps and becomes volumetrically linked to a corresponding congruent pair of shell penetrations, thereby creating, in an ordered temporal sequence, high conductance flow passages that extend completely through the valve. The azimuth-angle locations of the penetrations determine the relative times at which the valve's flow passages begin to open. The central angles of the penetrations determine the duration of the time intervals for which the flow passages are open or partially open. The radial extent of the penetrations determines the conductance of the flow passages.
