  In the last 20 years, Turbocharging has become generally used as a methods to increase  auto engine   power. A typical  Turbocharger   is made up of a compressor wheel and a turbine wheel installed on the same shaft. The exhaust gas expelled from the cylinder spins the turbine,which drives the compressor wheel. This Turbo sucks and compresses the sur r ounding air, then forces the much denser air into the intake manifold. If the turbocharger is spinning too fast, the pressure in the intake manifold becomes very high and can eventually damage the engine. Variable nozzle Turbos are equipped with a set of adjustable guide vanes positioned on the turbine stator. By changing the angle of the vanes, the turbine flow area and the angle at which the exhaust gas is directed at the turbine blades can be adapted in order to allow an optimum turbocharger operation over a large range of engine speeds. There are many different acronyms that are commonly used when referring ...
