Abstract

Electronic engine control systems have a plurality of individual components on the intake tube, some of them located relatively far from one another. For electrically connecting the individual components to the electronic control unit, relatively long electric connecting lines and a relatively large number of plug connections are therefore necessary. This invention sets forth a preassembled throttle apparatus which includes at least one throttle device, rotatably accommodated in a throttle valve support, and an idling adjuster in a housing; the throttle apparatus has a bypass conduit, which bypasses the throttle device and which can be varied by the idling adjuster, into which a regeneration valve can output fuel, the regeneration valve being triggerable by an electronic control unit that is also accommodated in the housing. The throttle apparatus of the invention is intended particularly for mixture-compressing internal combustion engines with externally supplied ignition.
