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.

An internal combustion engine with spark ignition, the engine including an exhaust gas turbocharger means for supplying supercharging air to the engine, a charging air line means for conveying supercharging air to an intake manifold of the engine, a throttle valve means arranged in a path of flow of the supercharging air for enabling a power control of the engine, and a bypass air line means connected to the charging air line means and terminating in an air inlet line at a position upstream of the turbocharger means, and a throttle means arranged in an inlet cross section of the bypass air line means, characterized in that the throttle means is constructed as a further throttle valve means, and in that means are provided for mechanically connecting the throttle valve means and further throttle valve means such that the throttle valve means opens as the further throttle valve means closes and vice versa, with the further throttle valve means of the bypass air line means closing somewhat earlier before the other throttle valve means is entirely open.
