ABSTRACT:
This application concerns a turbocharger control system and apparatus in association with a variable exhaust flow type turbocharger in which flow regulating turbine inlet vanes are positioned. The control includes a fluid pressure responsive device for actively positioning the inlet vanes. The device responds to opposing fluid pressure generated forces both of which are regulated in accordance with a program responsive to engine and vehicle parameters. The fluid pressures are the engine's intake manifold vacuum or pressure and the turbocharger's compressor output.
