Abstract
A mechanical engine governor includes a gear driven input shaft and an output shaft. A fly-weight assembly is mounted on the input shaft to apply a torque to the output shaft which varies as a function of the rotational speed of the input shaft. An output plate assembly is secured to the output shaft to rotate with the output shaft and is coupled to a fuel metering device such as a fuel injection system for a diesel engine. A stop plate is mounted to rotate about the output shaft, and a spring is mounted between the output plate assembly and the stop plate. At engine speeds below 500 RPM this spring rotates the output plate assembly with respect to the stop plate to provide increased fuel delivery to the engine during engine start up. At speeds greater than 500 RPM the stop plate insures that the governor commands no more than a predetermined maximum continuous fuel flow to the engine.
