Exhaust control
An exhaust control is used in the two-stroke engine to widen the speed range . The resonance speed of the engine is determined, among other things, by the discharge. The more advance the engine has, the higher the speed at which the engine has its power. However, with a large advance you lose performance at lower speeds.
This phenomenon can be avoided with a flap, a slide or a roller that changes the exhaust timing to the speed. These elements are moved mechanically, electrically or with the aid of the exhaust gas pressure and increase the exhaust control time and the cross section as the speed increases.
