  1. 6. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Adarsh Roy Choudhury; [2020]
    Nyckelord :Diesel Particulate Filter; Chemical Kinetics;

    Sammanfattning : Exhaust emissions in a vehicle has to flow through an exhaust aftertreatment in a diesel vehicle. In a diesel engine, the exhaust emissions are treated with Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), and Selective Catalytic Reduction (SCR). Every engine produces a different kind of soot depending on the drive cycle. LÄS MER

  2. 7. Mechanical modelling of gaskets in exhaust after-treatment system of trucks

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Aneesh Ravikumar; [2020]
    Nyckelord :;

    Sammanfattning : With the world proceeding towards a clean and sustainable environment,the creation of technology and its implementation also needs to be sustain-able. The importance of combustion engine vehicles to meet more stringentemission standards puts a requirement on the industry to develop suitableafter-treatment systems to meet those standards. LÄS MER

  3. 8. Catching Ash : Methodology for ash accumulation in diesel particulate filters

    Master-uppsats, KTH/Materialvetenskap

    Författare :Charis Pavlou; [2019]
    Nyckelord :diesel engine; diesel particulate filter; particulate matter; testing rig; accelerating ash accumulation;

    Sammanfattning : The diesel particulate filter captures particulate matter that is produced in the diesel engine. A small fraction of particulate matter is comprised by ash forming matter. When the combustible fraction of particulate matter is removed from the filter, the ash, which is incombustible, remains. LÄS MER

  4. 9. Evaluation of Supervised Machine LearningAlgorithms for Detecting Anomalies in Vehicle’s Off-Board Sensor Data

    Master-uppsats, Högskolan Dalarna/Mikrodataanalys

    Författare :Nor-Ul Wahab; [2018]
    Nyckelord :Anomaly detection; rule-based; one class support vector machine; k-nearest neighbor; random forest; confusion matrix; accuracy; precision; recall; F1-score;

    Sammanfattning : A diesel particulate filter (DPF) is designed to physically remove diesel particulate matter or soot from the exhaust gas of a diesel engine. Frequently replacing DPF is a waste of resource and waiting for full utilization is risky and very costly, so, what is the optimal time/milage to change DPF? Answering this question is very difficult without knowing when the DPF is changed in a vehicle. LÄS MER

  5. 10. A Method for Reducing Ash Volume in Wall-Flow Diesel Particulate Filters : Water Injection as a Service Tool to Improve Fuel Consumption and Particulate Filter Service Life

    Master-uppsats, Linköpings universitet/Maskinkonstruktion

    Författare :John Allen; [2017]
    Nyckelord :;

    Sammanfattning : In order to meet today’s environmental standards, diesel vehicles must capture the soot and ash emitted from the engine in what is known as a diesel particulate filter (DPF). The continual ash loading of this filter and subsequent exhaust backpressure, increase in fuel consumption, etc. is seen as an unavoidable expense. LÄS MER
