Abstract:
1. An engine comprising an engine body defining a combustion chamber therein, an induction system configured to guide air to the combustion chamber, an air metering device configured to meter an amount of air flowing through the induction system toward the engine body, the air metering device including a mechanical interface connectable to a mechanical power output request device so as to allow the air metering device to be adjusted mechanically between its maximum and minimum operating conditions, an electronic actuator capable of adjusting the air metering device between its maximum and minimum operating conditions, a switch configured to selectively enable and disable the electronic actuator from operating the air metering device between its maximum and minimum operating conditions, and a controller configured to operate in at least first and second modes, the controller being configured to disengage the actuator from the metering device, in the first mode, when the engine is operating at a speed above idle speed.
