1. Degradation of acrylonitrile butadiene rubber and fluoroelastomers in rapeseed biodiesel and hydrogenated vegetable oil
Sammanfattning : Biodiesel and hydrotreated vegetable oil (HVO) are currently viewed by the transportation sector as the most viable alternative fuels to replace petroleum-based fuels. The use of biodiesel has, however, been limited by the deteriorative effect of biodiesel on rubber parts in automobile fuel systems. LÄS MER
2. Towards sustainable heavy-duty transportation : Combustion and emissions using renewable fuels in a compression ignition engine
Sammanfattning : Transportation should become sustainable and available to everyone. Currently, transportation accounts for approx. one sixth of greenhouse gas (GHG) emissions globally, and heavy-duty trucks are responsible for almost 30% of that. LÄS MER
3. Deactivation of SCR catalysts - Impact of sulfur and the use of biofuels
Sammanfattning : In a near future, limits on CO2 emissions from vehicles will be introduced, which requires development of more fuel-efficient engines and most likely a transition towards the use of more biofuels. With the implementation of biofuels several issues could arise, one being the lack of fuel standards for these new type of fuels, leading to higher concentrations of catalyst poisons compared to conventional fossil fuels.

4. Experimental Studies on Using Butanol and Octanol Isomers as Drop-in Fuels for Diesel Engines
Sammanfattning : The increasing importance of transportation in modern societies has caused fossil fuel consumption to increase greatly in recent decades. However, burning fossil fuels in internal combustion engines can lead to high emissions of greenhouse gases, which cause climate change. LÄS MER
5. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines
Sammanfattning : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. LÄS MER
