  1. 1. Mathematical Modelling in Catalytic Automotive Pollution Control

    Författare :Lennart Andersson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; automotive pollution control; matematical modelling; monolith; selective catalytic reduction; mass transfer;

    Sammanfattning : Design and control of honeycomb monolith reactors for catalytic automotive pollution control by mathematical modelling of the reactor has been studied. One aspect of the design has been that the use of metallic monolithic catalysts for automotive emission control raises certain optimization possibilities. LÄS MER

  3. 2. Towards a sustainable automotive industry : experiences from the development of emission control systems

    Författare :David Bauner; Staffan Laestadius; Lee Schipper; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evolutionary economics; environmental innovation; trajectories; co-evolution; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : From the mid-1970s and on, the contribution to air pollution of carbon monoxide, hydrocarbons and nitrogen oxides from gasoline passenger cars in the developed world has been reduced through co-evolution of regulation and commercial introduction of catalytic emission control technology, now part of hundreds of millions of cars, trucks and buses worldwide. This dissertation is a disaggregated study of the global introduction of catalytic emission control technology as a measure to reduce local air pollution. LÄS MER

  4. 3. Distributed diagnosis and simulation based residual generators

    Författare :Jonas Biteus; Linköpings universitet; []
    Nyckelord :Diagnosis; Distributed diagnosis; Fault isolation; Residual generator; Simulation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Fault diagnosis is becoming increasingly important for many technical systems. This is for example true in automotive vehicles where fault diagnosis is needed due to economic reasons such as efficient repair and fault prevention, and legislations that mainly deal with safety and pollution.

  5. 4. On microstructure formation and mechanical properties in grey cast iron

    Författare :Attila Diószegi; Preben N. Hansén; Linköpings universitet; []
    Nyckelord :grey iron; nucleation; primary austenite; eutectic cell; growth rate; inoculation; thermal analysis; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : A major user of cast components is the automotive industry, where the functionality of the components is related to environmental demands. Internal combustion engines are constantly being improved to emit less pollution. A vital part in this development is to increase the material properties of engine components during their life cycle.
