Abstract

An electronically regulated fuel injection system for an internal combustion engine with a switchable safety and emergency driving device has a mechanical coupling which mechanically couples the accelerator pedal to the regulator. This coupling operatively interferes with a mechanical connection between a controller and the final control element that determines the quantity of fuel to be injected, after a fault signal has been outputted by a signal processing unit to a switchover element, which switches over control of the final control element to the simple regulator.
