A nonlinear system identification procedure, based on a polynomial NARMAX representation, is applied to a variable geometry turbocharged diesel engine. The relation between the variable geometry turbine (VGT) command and the intake manifold air pressure is described by a nonlinear model, directly identified from raw data. The intent of the paper is to explore the advantages of such a modeling procedure in automotive applications in terms of efficiency and complexity, in view of the related controller design and tuning problem. Simulation results on a HDI diesel engine model illustrate the whole procedure
