| The Wastegate principle represents the most basic version of variable turbocharger systems. The wastegate is an exhaust flap installed at the turbine inlet. By opening this flap, gas can bypass the turbine. As a result, the speed of the turbocharger and its boost pressure is limited in line with requirements.
The actorics for actuating the WG system can be self-regulating or operated by remote control. The most significant advantages of such a system are the simple and therefore cost-effective design, as well as relatively low installation requirements. |
