  3. 2. Control of EGR and VGT for Emission Control and Pumping Work Minimization in Diesel Engines

    Författare :Johan Wahlström; Lars Nielsen; Lars Eriksson; Gianfranco Rizzo; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : Legislators steadily increase the demands on lowered emissions from heavy duty vehicles. To meet these demands it is necessary to integrate technologies like Exhaust Gas Recirculation (EGR) and Variable Geometry Turbochargers (VGT) together with advanced control systems. LÄS MER
