Abstract
A horsepower limiting engine control limits the maximum engine horsepower output during operating conditions that might result in torque outputs that are greater than the transmission component ratings. The control includes an electronic controller connected to solenoid driver circuitry, an engine speed sensor and a gear selector. The solenoid driver circuitry energizes a solenoid in response to an engine speed less than a first predetermined engine speed value. The solenoid causes a moveable stop to retract permitting the engine to produce full rated power. The electronic controller causes the solenoid circuitry to de-energize and extend the moveable stop in response to the engine speed exceeding a second predetermined engine speed value and the gear selector being in a predetermined position.
