摘要： An engine system is disclosed. The engine system may have an engine, an intake duct, and a valve disposed within the intake duct and movable between a flow-passing first position, and a flow-blocking second position. The engine system may also have an actuator configured to move the valve from the second position toward the first position, and a biasing element configured to move the valve from the first position toward the second position. The engine system may additionally have a sensor configured to sense an operating condition of the engine, and a controller. The controller may be configured to receive an input indicative engine activation, and to activate the actuator based on the input. The controller may also be configured to make a determination that the operating condition of the engine has deviated from a desired operating condition, and to deactivate the actuator based on the determination.
