ABSTRACT:
A mechanical engine governor having centrifugal flyweights opposed by a high speed spring and a peak load control spring that acts against the high speed spring in a portion of its travel to flatten the peak horsepower curve wherein the combined springs have a decreasing rate to offset the exponential increase of force with speed of the flyweights and provide a fuel control actuating movement which is a constant function of the engine speed change. In a fuel-injected diesel engine having constant fuel input per cycle over the speed range, the result is a substantially constant maximum horsepower rating over a wide speed range. A power adjustment feature may also be provided.
