Thesis Work - Investigation of tribological properties for cylinders and piston ring combinations

We are now looking for students within mechanical engineering, material science or calculation and simulation that are interested in doing their thesis project at Husqvarna Group!

The surface properties of a cylinder bore and piston ring are crucial to engine performance. Production outcome and experimental surface treatments are today validated on product. Robust standalone evaluation methods are required for continued development of Husqvarna engines.

The objective 

Develop and evaluate a standalone test method consisting of test rig and mathematical analysis to assess tribological properties of different cylinder and piston ring combinations.

 

Proper area of education 

Bachelor or Master in Mechanical Engineering, Material Science or Calculation and Simulation.
 

The thesis will include work such as 

• Evaluate the tribological parameters of a cylinder bore through literature studies.

• Develop a test method where cylinder bore and piston ring are interacting at operational conditions.

• Develop a mathematical method to analyze the outcome.

 

How to apply   
Please send in your application with CV and cover letter no later than 28th of April. Due to GDPR, we do not accept applications by email.  

 

Start date of the thesis project is in the beginning fall of 2025, Q3.
