Abstract

An internal combustion engine includes a suction tract, a compressor disposed in the suction tract, and an exhaust tract. A secondary air system is fluidically connected to the exhaust tract at an introduction point and to the suction tract at a first branching point downstream of the compressor where a part of air compressed by the compressor is branchable off from the suction tract and is introducible into the exhaust tract at the introduction point. The secondary air system is fluidically connected to the suction tract at a second branching point upstream of the compressor where a part of air is branchable off from the suction tract by the secondary air system and is introducible into the exhaust tract at the introduction point. Air branched off at the second branching point is feedable through the secondary air system and is feedable to the introduction point by a secondary air pump.
