VARIABLE GEOMETRY TURBOCHARGER CONTROL SYSTEM

摘要

The disclosure relates to a control system for a turbo-charged engine having a variable geometry turbine driving a compressor. An intake manifold temperature sensor senses an intake manifold temperature. An intake manifold pressure sensor senses an intake manifold pressure. A turbine inlet temperature sensor senses a turbine inlet temperature. A turbine inlet pressure sensor senses a turbine inlet pressure. A control unit generates a vane position control signal which is applied to a vane control input of the turbine. The control unit generates the vane position control signal as a function of turbine inlet temperature and turbine inlet pressure.
