6. Defining Black: Characterization of Soot Reactivity with Thermogravimetrical Methods : Definiera svart: Karaktärisering av sotreaktivitet med termogravimetriska metoder
Master-uppsats, KTH/Tillämpad fysikSammanfattning : 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
7. Mechanical modelling of gaskets in exhaust after-treatment system of trucks
Master-uppsats, Linköpings universitet/Mekanik och hållfasthetsläraSammanfattning : 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
8. Catching Ash : Methodology for ash accumulation in diesel particulate filters
Master-uppsats, KTH/MaterialvetenskapSammanfattning : 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.

9. Evaluation of Supervised Machine LearningAlgorithms for Detecting Anomalies in Vehicle’s Off-Board Sensor Data
Master-uppsats, Högskolan Dalarna/MikrodataanalysSammanfattning : 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
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/MaskinkonstruktionSammanfattning : 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
