  4. 3. Parameter Estimation of a DOC from Engine Rig Experiments

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariate Data Analysis; Parameter Estimation; Exhaust Aftertreatment Modeling; Design of Experiments; Engine Test Bench; DOC; Full Scale;

    Sammanfattning : In this thesis methods of parameter estimation of a Diesel Oxidation Catalyst (DOC) from engine rig experiments were investigated. The investigation did not only include methods of parameter fitting to experimental data but a large effort was also put into catalyst modeling and experimental design. LÄS MER

  5. 4. Aspects of Efficient Parameter Estimation for Diesel Oxidation Catalysts

    Författare :Björn Lundberg; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MVDA; Mass Transport Modeling; Engine Test Bench; Design of Experiments; Kinetic modeling; DOC; Full Scale; Parameter Estimation; Exhaust Aftertreatment Modeling;

    Sammanfattning : In this thesis the objective was to tune the model parameters of diesel oxidation catalysts (DOC) to measurement data from engine rig experiments in an efficient manner. The scope was however not limited to the algorithm of parameter search alone but instead included the whole process starting with the design of experiments. LÄS MER
