Zusammenfassung:	An exhaust system and method for optimizing the efficiency of an internal combustion engine from which spent gas emerges. Spent gas is fed to an exhaust housing that accommodates a venturi. Part of the spent gas travels through the venturi and part travels outside the venturi. Across the mouth of the venturi sits a directing valve plate that can be moved, thereby opening or closing the path through the venturi. Some of the spent gas is reflected rearwardly from the venturi and thus reenters the cylinder. Upon doing so, the reflected spent gas occupies some of the space above the piston, lowers combustion pressure and reduces the velocity and pressure of the gas flow emerging therefrom.
