1. Characterization of NOx sensor performance under oscillating pressure conditions
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : The NOx sensor is essential in the modern after-treatment system. Due to the introduction of regulations from the US, it is necessary to investigate how these sensors operate in conditions of pulsating pressures generated engine - out, after the turbocharger.

2. Acoustic Characterization of Catalyst
Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)Sammanfattning : The WHO has set a sound level threshold of 55 dB, beyond which noise is considered harmful to humans when exposed for an extended period of time. It is, however, estimated by the European Environmental Agency that over 110 million people in the EU are regularly exposed to levels of traffic noise above 55 dB. LÄS MER
3. INVESTIGATING THE TOXIC AND ACIDIFYING EFFECT OF SCRUBBER EFFLUENT ON STRONGYLOCENTROTUS DROEBACHIENSIS LARVAE
Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskapSammanfattning : To meet the new environmental requirements of reduced sulfur emissions from ships, many shipowners have installed an open-loop scrubber to clean the exhaust. In this scrubbing process, seawater is pumped from the ocean and combined with the emission gas, creating an acidic and toxic effluent that is directly discharged into the ocean, potentially damaging the marine environment.

4. Design of flow guiding parts through CFD topology optimisation
Master-uppsats, KTH/FordonsdynamikSammanfattning : Scania works continuously to develop internal combustion engines and after treatment systems which can achieve low pollutant emissions and high efficiency. A major principal that Scania adopted for this goal is the Simulation Driven Development (SDD) process. LÄS MER
5. Evaluation of model-based fault diagnosis combining physical insights and neural networks applied to an exhaust gas treatment system case study
Master-uppsats, Linköpings universitet/FordonssystemSammanfattning : Fault diagnosis can be used to early detect faults in a technical system, which means that workshop service can be planned before a component is fully degraded. Fault diagnosis helps with avoiding downtime, accidents and can be used to reduce emissions for certain applications. LÄS MER
