In automotive applications problems related to control and diagnostics play an important role in the improvement of engine performance and in the reduction of fuel consumption and pollutant emissions. In this field theoretical models proved to be very useful, with applications that range from the definition of optimised management systems, to hardware-in-the-loop testing (HIL) and to model-based control strategies. However, control-oriented applications has to cope with the increasing complexity of actual automotive engines. In order to define “real-time” theoretical models for these applications, an original library has been developed by the authors for the simulation of complex systems [9,10,11], as intake and exhaust systems of automotive Diesel engines. “Quasi-Steady Flow” models and “Filling-and-Emptying” techniques were used for engine components and sub-systems.
