Claim:
1. An internal combustion engine comprising: at least one cylinder with an inlet side adapted to be coupled to an intake system and an outlet side adapted to be coupled to an exhaust-gas discharge system; at least one exhaust line for discharging exhaust gases from the cylinder to the exhaust-gas discharge system; at least one intake line for supplying charge air to the cylinder from the intake system; at least one exhaust-gas turbocharger comprising a compressor arranged in the intake system and a turbine arranged in the exhaust-gas discharge system; a bypass line for bypassing the cylinder, wherein the bypass line branches off from the intake system downstream of the compressor so as to form an inlet-side junction, and wherein the bypass line opens into the exhaust-gas discharge system downstream of the turbine; a recirculation line which branches off from the exhaust-gas discharge system upstream of the turbine so as to form an outlet-side junction which opens into the bypass line; a first control element at the outlet-side junction for adjusting an exhaust-gas quantity conducted through the recirculation line; and a second control element at the inlet-side junction having a first position that separates the bypass line from the cylinder and connects the intake line to the cylinder, and having a second position that separates the intake line from the cylinder and connects the bypass line to the cylinder.
