An apparatus for setting the throttle position in an air feed or intake assembly of an internal combustion engine in accord with desired torque including a two setting, switchable suction pipe. Torque fluctuations are inhibited during the switchover between the two settings so that uncomfortable drivability related effects are eliminated.
