ABSTRACT:
A regulating device is proposed for an internal combustion engine having a throttle device and a controllable bypass channel in the intake tube, where regulation is effected to a minimum volume (Q
) in overrunning above a predetermined rpm value and to the idling rpm below this rpm value. The purpose of this regulating device is the substantially precise preliminary control of an adjustment member in the bypass channel around the throttle valve to the opening cross section required for idling. The regulating device includes a switchover device (alternating switch), to the input terminals of which the output signals of the regulators for volumetric value and for idling rpm are applied. In the case of temperature-dependent minimum and threshold volumetric values, good warmup performance can be attained.
