  1. 1. Development of an Accelerated Test Method for Compressed Natural Gas Fuel System Robustness against Contamination

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Elias Aretorn; [2023]
    Keywords : CNG; Natural Gas; Heavy-Duty Vehicles; Fuel System; Contamination; Cleanliness; Accelerated Testing; Experimental Setup; Pressure Regulator;

    Abstract : A key factor for driving the shift towards sustainable transportation systems is alternative fuels, where compressed natural gas (CNG) is a beneficial alternative to the conventional fossil fuels with respect to greenhouse gas emissions. A fuel system is needed for heavy-duty natural gas vehicles, in order to transport the highly pressurized gas from the fuel tanks to the internal combustion engine. READ MORE

  4. 3. Life cycle assessment of coal based direct-reduced iron production in India

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

    Author : SABARISH ELANGO; [2020]
    Keywords : ;

    Abstract : The production of iron through direct reduction (Direct-Reduced Iron; DRI) involves the use of natural gas or coal to reduce iron ore to iron through carbothermic reactions at a temperature below its melting point, negating the need for a blast furnace as otherwise required. In India, around 25% of iron is produced through direct reduction. READ MORE

  5. 4. Flow and Air Quality Modelling of a Car Cabin

    University essay from Umeå universitet/Institutionen för fysik

    Author : Oskar Jolérus; [2019]
    Keywords : CFD; PM2.5; Air quality; Multiphase; LPT;

    Abstract : Adverse health effects attributable to both short- and long-term exposure to air pollution have turned the focus on different microenvironments. The interior of vehicles is of relevance as road traffic emissions and re-suspension of road dust are major sources of pollutants associated with adverse health effects. READ MORE

  6. 5. Effect of gritting sand quality on road dust pollution

    University essay from KTH/Vägtekniks laboratorium

    Author : Octavian Babiuc; [2016]
    Keywords : Pollution; road dust; particulate matter; gritting sand; studded tires; resistance to abrasion;

    Abstract : Pollution of air represents the contamination with matter that can affect both humanhealth and the environment. Road dust has been recognized as a dominant source ofparticulate matter and one of the factors that contributes to its development is the useof gritting sand. READ MORE
