METHOD AND DEVICE FOR DETERMINING THE PRESSURE UPSTREAM FROM THE TURBINE OF A SUPERCHARGING TURBOCHARGER OF A THERMAL ENGINE

摘要

The invention relates to a method for determining, in a turbocharger (1) for supercharging a thermal engine (4) including a turbine (2) and a compressor (3), the pressure (Put) upstream from the turbine (2) based on the inlet air flow (Qc), the pressure (Puc) upstream from the compressor (3), the temperature (Tuc) upstream from the compressor (3), the pressure (Pdc) downstream from the compressor (3), the temperature (Tut) upstream from the turbine (2) and the pressure (Pdt) downstream from the turbine (2).
