A Control-oriented Model for the Simulation of Turbocharged Diesel Engines
نویسندگان
چکیده
Theoretical models play an important role in the design of engine control and diagnostic systems, allowing to reduce development time and costs. The paper describes a control-oriented theoretical model for the simulation of an automotive Diesel engine built up using a “simulation library” developed in Simulink environment. Library blocks, defined for engine components and subsystems, were assembled together in a Mean Value Engine Model (MVEM) of a typical automotive Diesel engine, with Common Rail injection system, waste-gated turbine and EGR. Simulation results were compared with experimental data (both in steady and transient conditions) showing a good agreement. The model satisfactorily estimated engine behaviour both in steady and transient operation with very short calculation times.
