  1. 1. Model Based Catalyst Control

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Svraka Irman; Österdahl Wetterhag Linus; [2019]
    Nyckelord :Three Way Catalyst; lambda; Control; Emissions; Model; MATLAB; Simulink; Targetlink.;

    Sammanfattning : A one dimensional discretized model of a two brick three way catalyst (TWC) system was developed and implemented in MATLAB, Simulink and TargetLink in collaboration with Volvo Cars and Linköpings Universitet - ISY. The purpose of this thesis was to increase system understanding and create a model based TWC control for further development at Volvo Cars. LÄS MER

  3. 2. Adaptive air-fuel ratio control for combustion engines

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

    Författare :Eva Lundin; [2010]
    Nyckelord :;

    Sammanfattning : Around the world, vehicle emission regulations become stricter, increasing exhaust emission demands. To manage these rules and regulations, vehicle manufacturers put a lot of effort into minimizing the exhaust emissions. The three-way catalytic converter was developed, and today it is the most commonly used device to control the exhaust emissions. LÄS MER

  4. 3. An Investigation of Maximum Brake Torque Timing based on Ionization Current Feedback

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Janek Magnusson; [2007]
    Nyckelord :MBT timing; maximum brake torque; spark advance; PPP; tändningstidpunkt; maximalt arbete; MBT; jonström; jonströmsåterkoppling; PPP;

    Sammanfattning : For every operating condition of an internal combustion engine there exists an optimal spark timing, called maximum brake torque (MBT), which maximises the output torque and the efficiency of the engine. Traditionally MBT timing is implemented as an open-loop control where the ignition timing is found by using a combination of static lookup tables and sensor information. LÄS MER

  5. 4. Model Based Evaluation of UEGO Performance and Sensitivity

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Thommy Jakobsson; [2006]
    Nyckelord :wideband; narrowband; switchtype; uego; ego; oxygensensor; lambda;

    Sammanfattning : Closed loop fuel injection have been in use for two decades but it's not until the recent five years that the wide band lambda sensor have been utilized. The goal is to explain wide band and discrete lambda sensors in a simple but powerful way. LÄS MER

  7. 5. Ion Current Dependence on Operating Condition and Ethanol Ratio

    Uppsats för yrkesexamina på grundnivå, Institutionen för systemteknik

    Författare :Karin Gustafsson; [2006]
    Nyckelord :SI engine; black box modeling; engine speed; engine load; ignition timing;

    Sammanfattning : This masters thesis investigates the possibility to estimate the ethanol content in the fuel using ion currents. Flexible fuel cars can be run on gasoline-ethanol blends with an ethanol content from0 to 85 percentage. It is important for the engine control system to have information about the fuel. LÄS MER
