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

    University essay from Linköpings universitet/Fordonssystem

    Author : Jonatan Gustafsson; [2021]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 2. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    University essay from Linköpings universitet/Institutionen för fysik, kemi och biologi

    Author : Anton Åkervall; [2020]
    Keywords : 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;

    Abstract : 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). READ MORE

  4. 3. HYDROGEN-FIRED GAS TURBINE FOR POWER GENERATION WITH EXHAUST GAS RECIRCULATION : Emission and economic evaluation of pure hydrogen compare to natural gas

    University essay from Mälardalens högskola/Framtidens energi

    Author : Nemir Gibrael; Hamse Hassan; [2019]
    Keywords : harmful emission; natural gas; fuel reforming process; hydrogen fired gas turbine; exhaust gas recirculation; techno-economic analysis;

    Abstract : The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. READ MORE

  5. 4. Single cylinder research engine multi-spark ignition system

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Andreas Lius; [2018]
    Keywords : ;

    Abstract : I detta projekt presenteras ett arbete där en serieproducerad 5 cylindrig motor med gasdrift modifieras till drift på enbart en cylinder. En konceptstudie genomförs där för och nackdelar vägs mot varandra där sedan ett koncept implementeras. READ MORE

  6. 5. Model Based Control of Throttle, EGR and Wastegate : A System Analysis of the Gas Flows in an SI-Engine

    University essay from Linköpings universitet/Fordonssystem

    Author : Henrik Andersson; [2017]
    Keywords : Model; Control; SI-engine; gas-flow; system analysis;

    Abstract : Due to governmental requirements on low exhaust gas emissions and the drivers request of fast response, it is important to be able to control the gas flow in a spark ignited engine accurately. The air into the cylinder is directly related to the torque generated by the engine. READ MORE
