Abstract
A variable geometry turbocharger for an internal combustion engine in which the position of the nozzle ring is adjusted to control the width of an exhaust gas inlet passage. A chamber is defined behind the nozzle ring which communicates with the inlet passage and the pressure within that chamber is monitored. The monitored pressure is used as a control parameter for a mechanism which displaces the nozzle ring. Positioning a sensor in the recess behind the nozzle ring protects the sensor from the relatively more extreme environment within the engine exhaust gas manifold.
