  1. 1. Linearization Based Model Predictive Control of a Diesel Engine with Exhaust Gas Recirculation and Variable-Geometry Turbocharger

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Jonatan Gustafsson; [2021]
    Nyckelord :MPC; Model Predictive Control; LMPC; Linearization Based MPC; SLMPC; Successive Linearization Based MPC; Reference Generator; CasADi; EGR; Exhaust Gas Recirculation; VGT; Variable-Geometry Turbocharger; Diesel Engine; Heavy Duty Diesel Engine; Automatic Control; WHTC; World Harmonized Transient Cycle; Direct Multiple Shooting;

    Sammanfattning : Engine control systems aim to ensure satisfactory output performance whilst adhering to requirements on emissions, drivability and fuel efficiency. Model predictive control (MPC) has shown promising results when applied to multivariable and nonlinear systems with operational constraints, such as diesel engines. LÄS MER

  3. 2. A GENeric Internal Combustion Engine model : LiU-Genie

    Master-uppsats, Linköpings universitet/Fordonssystem

    Författare :Oskar Lind Jonsson; [2021]
    Nyckelord :;

    Sammanfattning : As the demand for control in modern vehicles grows, models are needed to develop a better understanding of processes and engine behavior. The thesis contributes with a generic extended MVEM with SI and CI as well as VVA compatibility and modeling structure using MATLAB/Simulink environment. LÄS MER

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Anton Åkervall; [2020]
    Nyckelord :DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

    Sammanfattning : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). LÄS MER

  5. 4. Impact of Pressure Pulsations on Diesel Air Path Control and Compensation Measures

    Master-uppsats, KTH/Maskinkonstruktion (Avd.)

    Författare :NISHANT DHANORE; [2019]
    Nyckelord :;

    Sammanfattning : Stricter pollution norms have led to increased efforts to achieve lower emissions. Exhaust Gas Re-circulation (EGR) is a well known measure to reduce NOx internally in the engine. In order to achieve better performance of an engine in terms of emissions it is very essential to control the flow of exhaust gases through EGR valve. LÄS MER

  7. 5. Utveckling av gasutbytesmodellering och reglerstrategi för spark ignited engine

    Master-uppsats, KTH/Mekatronik

    Författare :Pramod Swaminathan; [2018]
    Nyckelord :;

    Sammanfattning : Regeringens lagstiftare ökar ständigt kraven på att kontrollera utsläppen från tunga fordon för att upprätthålla hållbar miljö. Samtidigt ökar också behovet av snabb respons och lägsta bränsleförbrukning ur kundens perspektiv. LÄS MER
