  1. 1. Simplified models for emission formation in diesel engines during transient operation

    Författare :Anders Westlund; Hans-Erik Ångström; Martti Larmi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diesel engine; emission modeling; transient operation; NOx; Soot; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : The work presented in this thesis is the result of the KTH CICERO project “Dynamic Engine Performance” in which the main objective was to develop simple models foremission formation. The demand for such models is increasing, mainly due to the tightening emission legislation for diesel engines which has lead to more complex engines and thereby more laborious development and calibration processes.

  2. 2. Estimation and Prediction in Interdependent Systems in the Presence of Specification Errors

    Författare :Anders Westlund; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Mult i relät ional models involving simultaneously dependent linear equations are often employed in prediction and regulation of economic systems. The prediction purposes focus their attention on the reduced form of the model, relating each endogenous variable to exogenous variables, predicted outside the system. LÄS MER

  3. 3. Measuring and Predicting Transient Diesel Engine Emissions

    Författare :Anders Westlund; Hans-Erik Ångström; Rolf Egnell; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emission modelling; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Sammanfattning :   Due to its impact on human health and the nature surrounding us, diesel engine emissions have been significantly reduced over the last two decades. This reduction has been enforced by the legislating organs around the world that gradually have made the manufacturers transform their engines to today’s complex high-tech products. LÄS MER
