Modeling and Control of Turbocharged SI and DI Engines
A component based modeling methodology for turbocharged engines is described
and applied. Several component models are compiled and reviewed. In addition
new models are developed for the compressor efficiency, compressor flow, and
turbine flow. Two application examples are finally given where the modeling
methodology and the component models have been used. The applications are,
firstly, observer design and air/fuel ratio control of SI engines and,
secondly, control design of DI engines with VGT and EGR.
