Researcher in the formation of deposits in diesel injectors - Hiring in process/Finished, not possible to apply

Job description

The commercial vehicle industry is now undergoing a transformation from being a supplier of trucks, buses and engines to a supplier of complete and sustainable transport solutions. In in order to decrease the emissions of carbon dioxide from vehicle transports it is necessary to increase the share of renewable fuels in diesel. An increase of these so-called drop-in fuels can however lead to solubility problems and the formation of soft particles. These soft particles can give deposits in the fuel injection equipment and cause drivability problems. To be able to study and understand the mechanism behind internal diesel injector deposits (IDID) is important the increase use of drop-in fuels. KTH together with Scania and Scania Cummins XPI is studying this phenomenon in an ongoing project.

The project consists of three closely connected cornerstones that interacts with each other.

One is to study problems from the field by collecting fuel injectors, fuel samples and fuel filters from the field. This includes first developing methods on how to analyse the injectors and then understand what type of particles cause the injector failure and which part of the injector is affected. The second part is to reproduce the particles in the lab and by this understand how the particles are formed. The third part is to use these soft particles and reproduce the component problems in the lab.

Your role is to work within some of the three cornerstones. You will analyse injector deposits with analytical equipment e.g. XRD, TOF-SIMS etc. You will develop synthesis in the lab in order to produce test fuel containing soft particles/contaminants that represents European fuel contaminants. You will conform/re-build experimental test in the laboratory to study the IDID mechanism. And you will performed tests in the constructed injector test rig in order to recreates the same type of deposits that we see in the field and therefore study the IDID mechanism with that rig.

As support you will have close contact with Process Technology department at KTH, Materials Technology and Fuels System department at Scania CV AB and Cummins Scania XPI.

What we offer

• A position at a leading technical university that generates knowledge and skills for a sustainable future.
• Engaged and ambitious colleagues along with a creative, international and dynamic working environment
• Work in Stockholm , in close proximity to nature
• Help to relocate and be settled in Sweden and at KTH
