Ferramentas virtuais dinâmicas para processo de calibração de um sistema controle motor

Abstract

The national market competitiveness encourages the search for better effciency in internal combustion engines. As most of the time new technologies applied to these engines mean an increase in effort on the calibration and optimization processes. The automobile industry is investing in virtual tools that improve the development ofnewengines, reducing time.This paper aims at designing dynamic virtual calibrationtools to support the calibration base. For that, a methodology to use the tools, including data collection and selection, model structure selection and parameters validation was developed. This methodology was used to estimate three important variables for the dynamic calibration process: volumetric effciency, effective torque and catalyst temperature.
