ABSTRACT:
The present invention relates to an engine governor which interpolates between several fueling power curves based upon throttle position and engine speed. Each of the curves are chosen so as to provide a consistent power rise with decreasing engine speed at throttle positions less than maximum. The curves are chosen so as to eliminate an abrupt transition between the given fueling curve and the 100% fueling curve. This is preferably accomplished by having the fueling curve exhibit a knee at the transition to the 100% fueling curve. This gives the driver an indication that the throttle position will not maintain the desired speed under the current loading conditions, thereby prompting the driver to increase the throttle position, thereby allowing the throttle to be used to simulate infinite gear shifts between actual transmission gear shifts.
