  1. 1. Dynamics Study of an Automobile Exhaust System

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Johan Wall; Blekinge Tekniska Högskola.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Exhaust system; Experimental investigations; Finite element method; Flexible joint; Modal analysis; Model updating; Simplified modelling; Structural dynamics;

    Abstract : Low vibration levels are a critical objective in automobile exhaust system design. It is therefore important for design engineers to be able to predict, describe and assess the dynamics of various system design proposals during product development. READ MORE

  2. 2. Dynamic characteristics of automobile exhaust system components

    University dissertation from Karlskrona : Blekinge Institute of Technology

    Author : Thomas Englund; Blekinge Tekniska Högskola.; [2003]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Correlation; Exhaust system; Experimental investigation; Finite element model; Flexible joint; Modal analysis; Non-linear; Simplified modelling; Structural dynamics; Updating;

    Abstract : Demands on emission control, and low vibration and noise levels have made the design of automobile exhaust systems a much more complex task over the last few decades. This, combined with increasing competition in the automobile industry, has rendered physical prototype testing impractical as the main support for design decisions. READ MORE

  3. 3. Simulations of compressible flows associatedwith internal combustion engines

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Olle Bodin; KTH.; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Gas exhange; exhaust port; exhaust manifold; POD; DMD; exhaust; LES; Gasväxling; avgasport; avgasgrenrör; POD; DMD;

    Abstract : Vehicles with internal combustion (IC) engines fueled by hydrocarbon compoundshave been used for more than 100 years for ground transportation.During these years and in particular the last decade, the environmental aspectsof IC engines have become a major political and research topic.

  4. 4. Cardiovascular effects of diesel exhaust mechanistic and interventional studies

    University dissertation from Umeå : Umeå university

    Author : Magnus Lundbäck; Umeå universitet.; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; air pollution; diesel exhaust; nitrogen dioxide; endothelin-1; cardiovascular effects; exhaust particle trap; MEDICINE Dermatology and venerology; clinical genetics; internal medicine Internal medicine Lung diseases; MEDICIN Dermatologi och venerologi; klinisk genetik; invärtesmedicin Invärtesmedicin Lungsjukdomar; lungmedicin; Lung Medicine;

    Abstract : Background: Air pollution is associated with negative health effects. Exposure to combustion-derived particulate matter (PM) air pollution has been related to increased incidence of cardiovascular and respiratory morbidity and mortality, specifically in susceptible populations. Ambient particles, with a diameter of less than 2. READ MORE

  5. 5. Studies of a Heavy-Duty Diesel Aftertreatment System Based on the NOX Storage and Reduction Technology

    University dissertation from Department of Chemical Engineering, Lund University

    Author : Klaus Papadakis; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel penalty; injection parameters; DoE; design of experiments; exhaust; diesel engine; NO oxidation; simulation; modelling; oxidation catalyst; NOX trap; NOX storage and reduction; NSR; Kemiteknik och kemisk teknologi; Chemical technology and engineering; dosing strategy; system optimisation;

    Abstract : Popular Abstract in Swedish Gränsvärden för NOX-utsläppen i avgaserna från tunga dieselmotorer kommer att minskas i den Europeiska Unionen från 3,5 g/kWh (Euro IV) idag till 2,0 g/kWh (Euro V) år 2008. I USA och Japan är trenden likadan och utveckling av ett avgassystem för tunga dieselfordon verkar oundviklig. READ MORE
