  2. 21. Combustion characteristics of some alternative fuels in ICE: : a detailed numerical study

    Author : Siyuan Hu; Strömningsteknik; []
    Keywords : Combustion; duel fuel; methane; hydrogen; nheptane; methanol; DNS; simulation; openFoam; mixture-averaged; RCCI; ignition wave;

    Abstract : Two major fuels commonly used in compression ignition (CI) and spark ignition (SI) enginesare diesel and gasoline. The reserve of diesel and gasoline is limited, however the combustion ofthese fuels giving rise to air pollution. READ MORE

  4. 22. Evaluation of test cycles for freight locomotives

    Author : Mattias Skoglund; Stefan Östlund; Peter Thelin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; duty cycles; test cycles; diesel locomotives; locomotive emissions; dual modes; hybrid systems;

    Abstract : Diesel locomotives provide versatility to the railway system as they do not depend on electric feeding. Worldwide they constitute important parts of locomotive fleets used for various tasks such as mainline services, shunting and terminal operations. The main drawbacks are emissions of CO2, NOx and other pollutants. READ MORE

  5. 23. Lean Homogeneous combustion for SI-Engines

    Author : Gerben Doornbos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lean homogeneous combustion; lean limit.; Dual Coil Ignition; ammonia formation catalyst; valve-timing;

    Abstract : This thesis is about the application of lean homogeneous combustion in SI engines using a passive SCR after treatment system. By implementing this concept a decrease in fuel consumption and engine out NOx is expected. The data and results are obtained through engine experiments. READ MORE

  6. 24. High-speed optical and laser diagnostics - Internal combustion engines and gas turbine applications

    Author : Saeed Derafshzan; Förbränningsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fysicumarkivet A:2023:Derafshzan;

    Abstract : Increasing demands to meet regulations on combustion emissions and their environmental impact, and the need to improve their efficiency in different applications, have been the centre of focus in research and industry for decades. Optical and laser diagnostics have been proven to be amongst the best available tools due to their remote nature and non-intrusiveness, high spatial and temporal resolution, and their ability to investigate combustion processes and emissions in ways unprecedented before.

  7. 25. Model-Based Control of Gasoline Partially Premixed Combustion

    Author : Gabriel Ingesson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pressure-Sensor Feedback; Model Predictive Control; Model-Based Controller Design; Partially Premixed Combustion;

    Abstract : Partially Premixed Combustion (PPC) is an internal combustion engine concept that aims to yield low NOx and soot emission levels together with high engine efficiency. PPC belongs to the class of low temperature combustion concepts where the ignition delay is prolonged in order to promote the air-fuel-mixture homogeneity in the combustion chamber at the start of combustion.
