Exhaust system for a two-stroke internal combustion engine

摘要

Exhaust system for a two-stroke internal combustion engine with main exhaust port controlled by the piston arranged in the cylinder and with at least one additional exhaust port, forcibly controllable by means of a control device. In a known manner, a resonance chamber is arranged in or on the cylinder, which is also controlled by the control device for the additional exhaust port. The control device comprises a hollow piston or control piston, acted upon by the exhaust gas pressure of the exhaust port, with a flat slide valve, which has a control port or control recess for the resonance chamber. <IMAGE>
