The engine system also includes a first exhaust turbine arranged downstream of the engine and a second and third exhaust turbines coupled in parallel and arranged downstream of the first exhaust turbine. A first valve is associated with the second and third exhaust turbines, the first valve configured to at least partially restrict exhaust gas to one of the second and third exhaust turbines and increase exhaust gas to the other turbine. The engine system also includes an exhaust gas recirculation system configured to redirect at least a portion of exhaust gas from the exhaust system to the intake system.

摘要： A method of controlling a variable valve actuation system is provided. A cam assembly is operated to move an intake valve between a first position where the intake valve blocks a flow of fluid and a second position where the intake valve allows a flow of fluid. At least one operating parameter of the engine is sensed. A valve actuation period is determined based on the at least one operating parameter. A valve actuator is engaged with the intake valve to prevent the intake valve from returning to the first position in response to operation of the cam assembly. The valve actuator is released to allow the intake valve to return to the first position at the end of the determined valve actuation period.
