  1. 21. Inductive heating of exhaust aftertreatment system

    University essay from Lunds universitet/Industriell Produktion

    Author : Ludvig Nilsson; Kim Karlsson; [2018]
    Keywords : induction heating; exhaust aftertreatment; nox reduction; Technology and Engineering;

    Abstract : Heavy trucks are commonly powered by combustion engines running on diesel. Since these trucks often run on highways they rarely have to perform cold starts. READ MORE

  2. 22. Power and Methanol Production from Biomass Combined With Solar and Wind Energy : Analysis and Comparison

    University essay from KTH/Kraft- och värmeteknologi

    Author : Husni Firmansyah; [2018]
    Keywords : ;

    Abstract : The purpose of this work is to investigate the feasibility of an integrated system consisting of biomass-based power generation built-in with carbon capture technology combined with a water electrolysis unit operated by solar cells and wind turbines to produce fuel through the methanol synthesis process. The configurations are examined both technically and economically to determine their feasibility, and subjected to sensitivity analysis to determine their economic viability and optimum performance.

    Abstract : The legislation has forced the vehicle industry to reduce tail-end emissions. The air pollutant nitrogen oxide (NOX) has been shown to have a negative impact on human health and the environment. One of the key technologies to reduce the levels of NOX emitted from a vehicle is by implementing an after-treatment system. READ MORE

  4. 24. An alternative future for shipping – the way there : Risks and benefits of energy efficiency measures and alternative fuels for CO2 reduction in

    University essay from KTH/Marina system

    Author : Johanna Sunneland; María Sofía Gutiérrez Dufourq; [2018]
    Keywords : Alternative fuel; benefit analysis; capital expenses; operational expenses; carbon dioxide emission; CO2 emission; container ship; energy efficiency; environment; payback period; risk analysis; sustainability;

    Abstract : Shipping is the world’s largest mode of transportation, considering mass moved a distance: it is the most e˙effective way to carry large volumes far. In order for the shipping industry to keep its position and develop even further, efforts are made to increase efficiency and reduce the environmental footprint from the industry. READ MORE

  5. 25. PILCs for trapping phosphorus in a heavy duty engine exhaust system : An experimental evaluation of the phosphorus sorption capability of different clay materials

    University essay from Uppsala universitet/Strukturkemi

    Author : Anders Kvarned; [2016]
    Keywords : PILC; PCH; phosphorus sorption; exhaust treatment; catalyst poisoning;

    Abstract : In order to fulfil the requirements in the EURO VI standard, regulating emissions from heavy duty vehicles, the exhaust aftertreatment system needs to maintain its efficiency for at least seven years or 700 000 km. In diesel applications the diesel oxidation catalyst (DOC) is located closest to the engine and is thus the most vulnerable to poisoning contaminants, such as phosphorus originating from fuel and oil additives, which deactivates the catalyst.
