VALVETRAIN CONTROL SYSTEMS WITH INDEPENDENT INTAKE AND EXHAUST LIFT CONTROL |
摘要 |
A valve control system for an internal combustion engine includes a valve actuation system. The valve actuation system includes at least one of first and second configurations. The first configuration includes a shared lift control valve that actuates an intake valve and an exhaust valve between N open lift modes, where N is an integer greater than one. A second configuration includes a first lift control valve that actuates the intake valve and not the exhaust valve and a second lift control valve that actuates the exhaust valve and not the intake valve between the N open lift modes. A control module that enables transitioning of at least one of the intake and exhaust valves between the N open lift modes for the first and second configurations.
