Abstract (en)

[origin: EP1046800A2] The device regulates the choke flap position so that the engine drives a load at a constant speed irrespective of the power consumed by the load. The output of a choke position sensor (40) is connected to the input of a characteristic circuit (74) that converts it into a corrected position signal with a linear relationship to the engine's drive power and whose output is connecte a control characteristic gradient control circuit (96).
