1. Exhaust system for hydrogen fuelled combustion engines: effect of high-water content on the SCR vanadium catalyst
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : Transportation represents a key secot in the journey towards a greener future, and alternative solutions are needed to meet the decarbonaisation need. Hydrogen internal combustion engines could represent a solution in the short-term, allowing for emission reduction with limited modification to the already existing traditional combustion engines.

2. Characterization of NOx sensor performance under oscillating pressure conditions
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : 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.

3. Development and understanding of a model V2O5/anatase TiO2(101) SCR catalyst
University essay from Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionenAbstract : A model V2O5/ anatase TiO2(101) SCR catalyst is studied with the purpose of developing and understanding the reaction mechanism through which this catalyst reduces NOx. Several reaction mechanisms have been proposed for this catalyst in the past, but there is still no agreement on which of these describe the reaction the best, if any. READ MORE

4. Development of Elastic Mechanism for actuation of Valve
University essay from KTH/MaskinkonstruktionAbstract : The HGR valve, or hot gas recirculation valve, is an essential component of modern internal combustion engines. Its main function is to reduce emissions of nitrous oxide (NOx), which is a harmful pollutant produced during combustion. READ MORE

5. Acoustic Characterization of Catalyst
University essay from KTH/Skolan för teknikvetenskap (SCI)Abstract : 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. READ MORE
