    摘要: The invention relates to a method and apparatus for limiting road speed in electrically controlled diesel engines. The output signal of the road-speed transducer or, if the road-speed transducer is defective, the output signal of the engine speed transducer is evaluated by means of pregiven thresholds. In the presence of a simultaneous clutch signal and a quantity signal which is less than a pregiven injection quantity a waiting time is made available in advance of the quantity reduction so that when the clutch is actuated, fuel can be metered when the clutch pedal is depressed or the vehicle can be started on a hill. No transmission signal is necessary for limiting road speed whereby manipulations on the road-speed limitation are prevented.

    摘要: An electronic control system for fuel injection of a diesel engine includes a field of characteristics for a smoke discharge limiter which is controlled either by a field of correction characteristics of charging air pressure in dependency on signals derived from sensors of operational parameters of the engine, or alternatively by a simulation unit operating without the use of sensors. The decision whether or not the control and/or regulation of the diesel engine is to be made in dependency on sensors is made by an evaluation circuit which evaluates operational condition of the engine, for example by means of a plausibility interrogation.
