Abstract
A stabilizer system creates a temporary droop to stabilize a governor for an internal combustion engine and reduce permanent droop and hunting of the engine. The governor adjusts the position of a throttle in response to engine speed to achieve a desired engine speed. The stabilizer system temporarily applies a force on the governor that initially resists sudden movement of the governor arm, and causes a temporary speed droop. The initial resistance of the stabilizer system helps prevent the governor from overshooting the desired speed and hunting. The temporary droop is then removed to permit the governor to achieve the desired speed to help prevent permanent droop.
