Also in this context: exhaust/emissions/waste gas -------------------------------------------------- Note added at 2002-06-05 09:21:06 (GMT) -------------------------------------------------- \"Wastgate\" should read \"wastegate\" in the German -------------------------------------------------- Note added at 2002-06-05 09:27:56 (GMT) -------------------------------------------------- e.g. http://www.motorsport-developments.co.uk/why_fit_one.htm The wastegate actuator takes a pressure feed from the turbochargers compressor wheel, which in turn feeds the engine with compressed air. As compressed air, for any given volume, contains more oxygen, the resulting mixture burns more intensely giving more power for a given cubic capacity than a normally aspirated (non-Turbo) engine. On most turbo cars currently in production, the maximum boost pressure which the engine \"sees\" is ultimately controlled by the wastegate actuator. The sole job of the wastegate actuator, is to act as a pressure relief valve that controls the turbocharger boost output. The main parts of an actuator are the spring and diaphragm, the spring holds the wastegate shut until the turbo is delivering a predetermined boost level and then opens, allowing the exhaust gas to escape and slow the turbine. |
