exhaust valve - a valve through which burned gases from a cylinder escape into the exhaust manifold. exhaust system, exhaust - system consisting of the parts of an engine through which burned gases or steam are discharged. valve - control consisting of a mechanical device for controlling the flow of a fluid.
A wastegate is a valve that diverts exhaust gases away from the turbine wheel in a turbocharged engine system. Diversion of exhaust gases regulates the turbine speed, which in turn regulates the rotating speed of the compressor.n internal wastegate is a built-in bypass valve and passage within the turbocharger housing which allows excess boost pressure to dump into the downstream exhaust. Control of the internal wastegate valve by a pressure signal from the intake manifold is identical to that of an external wastegate.
