  1. 1. 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

  3. 2. 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

  4. 3. Experimental investigation of EGR mixing and distribution on a HD diesel engine with variable venturi EGR control valve

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Krister Gritzun; Vijayaraghunathan Rajagopal; [2012]
    Nyckelord :;

    Sammanfattning : För att klara de allt hårdare emissionskraven utan efterbehandling kan blandning, kontroll och jämn fördelning av EGR mellan dieselmotorns cylindrar komma att bli allt viktigare. Genom att åstadkomma högre inloppstryck än avgasmottryck kan vinster i bränsleförbrukning uppnås men detta skapar problem att tillföra EGR till motorns insugsida. LÄS MER

  5. 4. A Method for Estimating Soot Load in a DPF using an RF-based Sensor

    Master-uppsats, Institutionen för systemteknik; Tekniska högskolan

    Författare :Victor Ingeström; John Hansson; [2012]
    Nyckelord :Soot Sensor; Diesel Particulate Filter; Black Box; Average Gain;

    Sammanfattning : The European emission standard is an EU directive which describes what emission limits car manufactures are required to meet. In order to meet these requirements car manufacturers use different techniques and components. In a modern diesel automobile a Diesel Particulate Filter (DPF) is used to gather soot from the exhausts. LÄS MER
