More Information
Summary:The invention relates to a method for modeling the compressor speed of a turbocharger, comprising the steps of determining the temperature difference across the compressor, determining the mass flow through the compressor, and calculating a compressor speed value as a function of the temperature difference across the compressor and the mass flow, wherein the step of calculating the compressor speed value is performed using Nturbo ∝ dmgasdtR˜Tboost−Tin, where Nturbo is the compressor speed, dmgasdt is the mass flow, R̃ is a corrected ideal gas constant, and Tboost - Tin is the temperature difference across the compressor.
