Abstract (en)
[origin: US4572126A] The invention is directed to an apparatus for controlling the overrun mode of operation of an internal combustion engine in dependence on the instantaneous rotational speed and a threshold characteristic of a resume speed. A throttle valve position sensor, a speed comparator and an evaluation circuit for determining a fuel supply cutoff or a fuel metering signal are provided. Means responsive to engine speed or actuable at the operator's discretion permit the circuit to be held in a state in which the overrun cutoff signals are suppressed. If these means are speed-dependent, a dynamic suppression for a predetermined period of time results; the means utilized for suppressing the overrun cutoff function may also be actuated in response to external driving situations or in response to the conditions of other components of the vehicle.
