ABSTRACT:
A mechanical injection pump governor is provided having a first adapting device which acts in the lower speed range up to the full-load characteristic curve of a supercharged diesel engine for adapting the delivery quantity of the injection pump to the fuel requirement of the diesel engine. The adapting device contains a spring-loaded diaphragm which is acted upon by a supercharge and is connected to the control rod of the injection pump. The lift of the diaphragm, when supercharge pressure is applied, is limited by a full load stop which determines the adapting end point. To improve the torque profile of the diesel engine, a second adapting device is provided which adjusts the full load stop. By means of this second adapting device, the full load stop can be displaced against an additional spring force when supercharge pressure is progressively applied so that the delivery quantity of the injection pump increases between the adapting end point and the rated speed of the diesel engine.
