waste·gate ('wAst·'gAt), n. 1. An exhaust bypass valve employed by turbocharged engines used to control boost pressure by means of alternating exhaust gas flow either to or away from the turbine.

GM has filed a patent for a sequential twin-turbo system that uses a new bypass valve design said to optimize exhaust flow to the turbines of both turbochargers. GM Inside Newsdiscovered the new ...

As it turns up, there’s a solution to this very first-world problem: you can just install an exhaust bypass valve controller and then you can open the exhaust whenever you want and without ...

This allows exhaust gases to bypass the turbine, regulating the turbocharger's revolutions per minute. ... They also have ...

The valves are suitable for exhaust gas temperatures of up to 750° C (peak) and ambient temperatures of up to 140° C (peak). The valve delivers important acoustical benefits as well.

The start-up bypass valve and line (14-inch NPS) maintain the start-up temperatures below the carbon steel limits by reducing the HP exhaust pressure at start-up to less than 50 psig.

Now select ‘Sport’ mode (this leaves the exhaust bypass valves open, sharpens the throttle response and quickens the VDC stability control system), pull back on the right-hand gearshift paddle ...

The exhaust bypass valve helped the engine pass noise regulations, but can become rattly. It isn't damaging to the engine but is expensive to replace and many owners do away with it completely by ...
