Introduction
Thesis project at Scania is an excellent way of building a network for your future working life and learn more about the ongoing transformation towards a more sustainable transport system. Many of our current employees started their career with a thesis project at Scania.

 

Background 
Scania is undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions. One important part in this strive is the use of hydrogen as an alternative fuel. 

Hydrogen produced from renewable sources such as wind- or solar power offers an alternative to battery electric in applications where for example long range and fast fuelling are important features. 

 

The hydrogen could be used either in fuel cells generating electricity or directly in specially adopted internal combustion engines (H2-ICE). The latter is a fairly mature technology which will be an important part in the implementation of hydrogen fuelled heavy trucks. 

The use of hydrogen will offer new challenges for the design of the trucks exhaust aftertreatment system as the exhaust temperatures and composition will differ greatly for common diesel or petrol engine exhausts. But it also opens up new opportunities at cold-start conditions hydrogen can react with oxygen form the air over a catalyst to produce heat either to heat up the engine itself or the exhaust system. This process have been shown possible even at sub-zero temperatures. In the exhaust system the hydrogen could also act as a reductant in the de-NOX system. 

 

Objective 
The work aims at studying the performance and use of catalytic hydrogen combustion as a mean to overcome cold-start problems and improve ignition of hydrogen fuelled engines. This is an exciting novel approach to the use of catalysts on-board a hydrogen fuelled vehicle and has a great potential for improvement of the performance and emissions. 

 

Job description 
The assignment will cover the whole process from idea to design of experiments and testing. It will include both theoretical and hands-on work in the laboratory as well as the use of advanced characterization techniques. The assignment involves contacts with different experts both at Scania and KTH.  

 

We expect you as a candidate to have a curious mindset and a will to see things through from idea to final product. You will work in a dedicated team of driven experts from many aspects of engines and exhaust aftertreatment technologies.

 

The work will be performed mainly at Scania Materials Technology in Södertälje and some work at Process Technology, KTH.
