  1. 1. Multiscale methods for the fundamental understanding of diesel soot mitigation

    Author : Carl Justin Kamp; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nanofabrication; Catalyst; Soot; Aftertreatment; Carbon; Particulate Matter; Oxidation; Ash; Diesel Particulate Filter;

    Abstract : Current regulations for diesel exhaust emissions cannot be met by engine improvements alone, and for this reason the diesel particulate filter (DPF) is a widely used aftertreatment component for the control of diesel particulate matter (PM). The DPF functions by trapping PM and destroying it by oxidation. READ MORE

  2. 2. Analysis of carbon black oxidation

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Soheil Soltani; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; diesel particulate filter DPF ; deconvolution; inverse problems; residence time distribution; computational fluid dynamics CFD ; kinetic modeling; transient kinetics;

    Abstract : Diesel engines are known to be a major source of a highly pollutant material known as particulate matter, PM, which is a strongly threatening agent to human health. Therefore, diesel particulate filters are used to reduce PM emissions by trapping soot. READ MORE

  3. 3. Acoustic modelling and testing of advanced exhaust system components for automotive engines

    University dissertation from Stockholm : Farkost och flyg

    Author : Sabry Allam; KTH.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; acoustic modelling; testing; two-port; diesel particulate filter; after treatment device; Teoretisk fysik; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik;

    Abstract : The increased use of the diesel engine in the passenger car, truck and bus market is due to high efficiency and lower fuel costs. This growing market share has brought with it several environmental issues for instance soot particle emission. READ MORE

  4. 4. Deactivation of emission control catalysts for heavy-duty vehicles Impact of biofuel and lube oil-derived contaminants

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Sandra Dahlin; KTH.; [2020]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; catalyst deactivation; diesel oxidation catalyst; sulfur; phosphorus; biodiesel; heavy-duty; emission control; regeneration; alkali metals; NH3-SCR; Cu-SSZ-13; V2O5-WO3 TiO2; katalysatordeaktivering; dieseloxidationskatalysator; svavel; fosfor; biodiesel; tunga dieselmotorer; avgasrening; regenerering; alkalimetaller; Chemical Engineering; Kemiteknik;

    Abstract : Catalytic emission control is used to reduce the negative impact of pollutants from diesel exhausts on our health and on the environment. For a heavy-duty truck, such a system consists of a diesel oxidation catalyst (DOC), a diesel particulate filter (DPF), a selective catalytic reduction (SCR) catalyst, and an ammonia slip catalyst (ASC).

  5. 5. Particles and unregulated emissions from CI engines subjected to emission control

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Kent Nord; [2005]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chemistry of Interfaces; Gränsytors kemi;

    Abstract : Compression ignited (CI) engines, commonly known as diesel engines, are widely used power sources with complex emissions used in on-road and nonroad applications. To find out the impact of diesel exhaust emissions on health and the environment, both regulated and unregulated exhaust gas properties have to be evaluated. READ MORE
