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.

Air inlet arrangement for an internal combustion engine with a torque determined throttle setting

An electronic control device for the optional control of various types and operating modes of internal combustion engines includes a calculation device configured to calculate the respectively required manipulated quantities, including at least the manipulated variable (Ti) for the predetermination of the fuel quantity to be injected and the manipulated variable (&agr;) for the predetermination of the throttle valve position of the throttle valve in the intake pipe, dependent on respectively required input parameters, including at least the desired quantity of heat (WM). A switchover device is configured to allocate, dependent on the operating mode, the respectively required input parameters and/or quantities derived therefrom as input quantities for the respectively required calculation device. A single type of control device may be manufactured, in large piece counts and with simplified warehousing, for variable possibilities of application. The adaptation to the respective type of engine or operating mode may occur through simple adaptation with the aid of a switchover device.
