30 credits – Robust emission control system for sustainable transport

Scania genomgår nu en transformation från att vara en leverantör av lastbilar, bussar och motorer till en leverantör av kompletta och hållbara transportlösningar.


Thesis project at Scania is an excellent way of making contacts for your future working life. Many of our current employees started their career with a thesis project.


Scania is driving the shift towards sustainable transport. Energy efficiency, alternative fuels and electrification, and smart and safe transports are the three pillars of sustainability for Scania. A robust emission control system for heavy-duty diesel engines is a key success factor for achieving long lasting, cost effective transport solutions with high performance and minimized environmental impact. 

Diesel engines have the advantages of being highly efficient and easily adapted to different types of renewable fuels. This gives the diesel engine a prominent place in the low-carbon future.

The emissions of nitrogen oxides (NO


) are a drawback of diesel engines, which can lead to air quality and health issues.

Scania’s diesel engines have a world-leading exhaust treatment system that lowers NO


emissions well below the strictest regulations. Nevertheless, at Scania we keep working to maintain our leadership and develop even better and more durable systems for meeting future challenges.

In this master thesis project you will work with selective catalytic reduction (SCR) catalysts, whose task is to reduce NO




The targets of this master thesis project are 1) to develop a lab methodology to study the chemical deactivation of a SCR catalyst, and 2) to assess how chemical deactivation impacts the catalyst’s performance over time.


You will investigate how the SCR catalyst tolerates different compounds that could adversely affect its performance over time. For this task you will use a new, advanced instrument (TGA-FTIR-GC/MS). It is very accurate thermobalance with a gas measuring system, which is one of a kind in Scandinavia. You will set up methodologies for probing the catalyst, understand fundamental physical and chemical phenomena, correlate results to real-life operation, and document and present your results. 

You will work in a team of dedicated and driven experts on many aspects of engine and exhaust treatment technologies.

The work will be performed at Scania Materials Technology in Södertälje in cooperation with the Department of Chemical Engineering and Technology at KTH.


Master student in chemistry, chemical engineering, material science, engineering physics or equivalent. You should have an interest in experimental work and the ability to address technical challenges in the laboratory. The ability to work independently, interest in problem solving and a curious mindset are very valued qualities.
