  1. 21. 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. 22. Temperature Based Estimation of the Time-Resolved Massflux of ICE Exhaust Gas Flow

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Mayur Khedekar; [2021]
    Keywords : ICE exhaust flow condition; Thermocouples; Resistance wire thermometers; Nu correlations; ICE exhaust Mass-fluxstudy; Heat transfer coefficient; Heat balance equation for thermocouple; Constant current anemometry; ICE-avgasflödesförhållande; Termoelement; Motståndstrådstermometrar; Nu-korrelationer; ICE-avgas Massflödesstudie; Värmeöverföringskoefficient; Värmebalansekvation för termoelement; Konstant strömanemometri;

    Abstract : The aim ofthe study was to provideinformation and experience gained with fine wire thermocouples (TCs)or resistance wire thermometers (RWTs) temperature signals to estimate the timeresolved heat transfercoefficient. Constant current method was assumed in the study and medium used in this study was air. READ MORE

  4. 23. The Potential of Electrification in reducing Emissions from Passenger Cars in Stockholm County by 2030 : A Modeling Study of the Potential of Plug-In Hybrids and All-Electric Cars in reducing Greenhouse Gas Emissions and Air Pollution

    University essay from KTH/Transport och systemanalys

    Author : Arvid Hedbäck; [2021]
    Keywords : electric cars; electrification; Stockholm; 2030; modeling; Scaper; HBEFA; CO2; air pollution; nitrogen oxides; NOx; hydrocarbons; HC; particulate matter; PM10; PM2.5;

    Abstract : This study examines the potential of electrification in reducing greenhouse gas emissions and air pollution from passenger cars in a short- to mid-term time perspective. Using Stockholm County as a case study, this has been done in a three-step process by modeling the relative change in emissions between 2019 and 2030. READ MORE

  5. 24. Liquid Natural Gas : A study of the environmental impact of LNG in comparison to diesel

    University essay from Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Author : Jonas Edfors; Robin Bremberg; [2021]
    Keywords : Methane; LNG; Engine; Marine; Mole; Methane Slip; Ship; CO2; CH4; Emission; IMO; Exhaust gas; Environment; Propulsion; Heavy Fuel Oil; Ultra Low Fuel Oil; Diesel; Marine Diesel Oil; ECA; SECA; NECA; IMO; g kWh; EEDI; LSFO; Metan; LNG; Motor; Mol; Skepp; Miljö; Miljövänligt; Tjockolja; Diesel; Marine Diesel; Avgas; CO2; CH4; ECA; SECA; NECA; IMO; g kWh; EEDI; LSFO;

    Abstract : Liquefied Natural Gases (LNG) has been an alternative fuel in the marine industry for several years, but lately, the amount of ships that have been powered by methane has increased a lot. Some of the reasons for this is because LNG does not contain any sulfur and releases less nitrogen oxides than traditional maritime fuels. READ MORE

  6. 25. Identifying risks of AdBlue spray on stainless steel surfaces

    University essay from KTH/Kemiteknik

    Author : Evelina Tvinne Flyg; [2021]
    Keywords : Urea; Stainless steel; SCR; Deposit; Corrosion; Urea; rostfritt stål; SCR; Avlagring; Korrosion;

    Abstract : Utsläppskontroll, reglerad av allt strängare lagstiftning, ställer höga krav på utvecklingen av noggranna efterbehandlingssystem för avgaser. När det gäller utsläpp från dieselmotorer utgör NOx-minskning en av de största utmaningarna. För tunga fordon tacklas denna utmaning ofta genom ett SCR-system. READ MORE
