Method for determining the temperature downstream the entry of a catalytic converter for a turbocharged engine

摘要

This method for determining, in a turbocharged engine, the temperature of the exhaust gases downstream of the turbine of the turbocharger, comprises the following steps: determining the temperature upstream of the turbine of the turbocharger, calculating a corrective term from engine operating parameters, and determining the temperature downstream of the turbine of the turbocharger by subtracting the corrective term from the temperature upstream of the turbine of the turbocharger.
