Abstract
An altitude fuel limiter and method for controlling an engine using the same is provided. The altitude fuel limiter includes a torque screw sleeve extending from an inboard end to an outboard end. The torque screw sleeve has an interior surface defining a central bore extending axially within the torque screw sleeve. A plunger is disposed within the central bore and moves axially between a first position and a second position. A plunger regulator senses ambient pressure and is coupled with the plunger to axially displace the plunger toward the inboard end of the torque screw sleeve to the first position in response to sensing an ambient pressure that is below a predetermined pressure. The predetermined pressure may be associated with non-compliant altitudes and the plunger limits fuel delivered to the engine when displaced to the first position.
