Abstract
An rpm governor for fuel-injected internal combustion engines is proposed, in particular a centrifugal rpm governor of an injection pump for Diesel motor vehicles, in which the idling rpm is also held constant when the engine is cold or loaded by additional consumers, in order to assure smooth running of the engine and the most favorable values for fuel consumption and exhaust emissions. The governor contains an idling correction apparatus with an electromagnet, which transmits an additional adjustment force, which is preferably independent of travel distance and variable only by the energizing current of a control circuit, onto the governor member via a transmission element. By means of varying or switching on or off of the adjustment force, the idling rpm which is fixed by the initial stress of an idling spring for the warm and unloaded engine is also held constant under changing operational conditions.
