Multiple Choice

In a turbocharger system, the speed of the turbine (and therefore the impeller and amount of supercharging) is controlled by the position of the ______ gate.

The speed of the turbocharger turbine (and the amount of boost) is controlled by the position of the waste gate. The waste gate is a valve that decides how much exhaust gas goes through the turbine versus bypassing it. When the waste gate is closed, most exhaust flows through the turbine, making it spin faster and increasing boost. When the boost reaches the desired level, the waste gate opens and diverts exhaust away from the turbine, slowing it down and preventing over-boost. The throttle valve controls how much air enters the engine, not the turbo’s speed. The other valves aren’t used to regulate turbo operation in this way (EGR recirculates exhaust for emissions, and a plenum valve isn’t a standard component for controlling turbo boost).
