  1. 1. Injection Strategies for Heavy Duty DI Diesel Engines

    Författare :Tanja Rente; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; multiple injections; injection pressure; local heat transfer; diesel combustion; injection duration; orifice number; injection strategies;

    Sammanfattning : Diesel engines enjoy widespread popularity in transportation and industrial systems. The reasons for this popularity are their simplicity, relatively low capital costs, durability and high fuel efficiency. LÄS MER

  2. 2. On the Combustion Characteristics of Closely-Coupled LD Diesel Injection Strategies

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Knock Mitigation; Downsized SI engine; RON; Water Injection; Particulates; Relative Humidity;

    Sammanfattning : In recent years, there has been a major shift towards the partial or complete electrification of vehicles that have traditionally been powered by conventional internal combustion (IC) engines; almost all major automotive manufacturers have rightly stated that they will make such a shift. This has been motivated in large part by pressure from governments and policymakers to minimize vehicular emissions, especially those of the greenhouse gas CO2, in order to control climate change.

  4. 4. Spray combustion with multiple-injection in modern engine conditions

    Författare :Ahmad Hadadpour; Strömningsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Spray combustion; Multiple-injection; Internal combustion engine; LES; FGM; ESF;

    Sammanfattning : Combustion of fuel in diesel engines emits substances harmful to the environment such as soot. These emissions can be reduced by either in-cylinder treatments or after-treatments. One of the common in-cylinder treatments is multiple-injection, which divides a single fuel injection to multiple smaller injections. LÄS MER

  5. 5. Strategies to improve cancer radioimmunotargeting

    Författare :Anders Ullén; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; : cancer; monoclonal antibody; antiidiotypic antibody; radioimmunotargeting; placental alkaline phosphatase; cytokeratin; BIAcore.;

    Sammanfattning : Radioimmunotherapy (RIT) and radioimmunolocalisation (RIL) are developing and promising technologies to diagnose and treat tumours by use of radiolabelled antibodies targeting tumour specific antigens. The major reason why RIL and RIT not are efficient enough, is the comparatively low accumulation of radiolabelled antibodies in the tumours. LÄS MER
