Abstract
An emergency control apparatus is proposed for a fuel metering system in a Diesel engine, where the signal processing unit (microcomputer) and/or a regulator can be bypassed. In the case of the failure of the signal processing unit, the position signal of the driving pedal is switched more or less directly to the regulator for triggering the control unit for the quantity-determining member, and if there is a failure of the regulator, a purely proportional regulator comes into action. It is thus assured that even in the case of failure emergency operation is guaranteed, the course of which emergency operation can essentially be influenced only by the driver of the vehicle.
