  1. 21. Optimal control of a diesel engine with EGR and VGT

    University essay from Institutionen för systemteknik

    Author : Markus Welander; Jonas Olsson; [2006]
    Keywords : TOMOC; Matlab; PID controller; fmincon;

    Abstract : To fulfill todays requirements on emissions from engines, SCANIA has developed an engine with EGR (Exhaust Gas Recirculation) and VGT (Variable Geometry Turbine). This gives two extra control signals to take into consideration. READ MORE

  3. 22. System analysis of a diesel engine with VGT and EGR

    University essay from Institutionen för systemteknik

    Author : Thomas Johansson; [2005]
    Keywords : diesel engine; VGT; EGR;

    Abstract : To fulfil emission requirements specified by environment demands, such as Euro 4 and Euro 5, there is a need to utilize engines based on technologies such as Variable Turbine Geometry (VGT) and Exhaust Gas Recirculation (EGR). A model of an engine using VGT and EGR was created by Ph.D student Johan Wahlström at Linköping University. READ MORE

  4. 23. Gas flow observer for Diesel Engines with EGR

    University essay from Institutionen för systemteknik

    Author : Fredrik Swartling; [2005]
    Keywords : Technology; EGR; Mean Value Engine Model; Observer; Lambda; TEKNIKVETENSKAP;

    Abstract : Due to stricter emission legislation, there is a need for more efficient control of diesel engines with exhaust gas recirculation(EGR). In particular, it is important to estimate the air/fuel ratio accurately in transients. Therefore a new engine gas flow model has been developed. READ MORE

  5. 24. Modelling of a Variable Venturi in a Heavy Duty Diesel Engine

    University essay from Institutionen för systemteknik

    Author : Carl-Adam Torbjörnsson; [2002]
    Keywords : Technology; Exhaust gas recirculation; On-board Diagnostic; Flow meter; Model Based Diagnostic; Restriction; Compressible; Incompressible; TEKNIKVETENSKAP;

    Abstract : The objectives in this thesis are to present a model of a variable venturi in an exhaust gas recirculation (EGR) system located in a heavy duty diesel engine. A new legislation called EURO~4 will come into force in 2005 which affects truck development and it will require an On-Board Diagnostic system in the truck. READ MORE
