Abstract
An internal combustion engine with spark ignition having an exhaust gas turbocharger. Supercharger air from the turbocharger is conveyed through a charger air line or pipe to an intake manifold of the internal combustion engine. A throttle valve is provided for the power control of the engine in a path of the supercharger air, especially at an inlet to the intake manifold. A bypass air line or pipe is connected to the charger air line or pipe, with the bypass air line extending to a position upstream of the turbocharger. A further throttle valve is arranged at the bypass air line with both throttle valves being mechanically connected with each other in such a manner that one throttle valve closes when the other throttle valve opens, and vice versa.
