Södertälje, Stockholm, Sweden Scania Full time 450,000 - 675,000 per year

Scania is a global leader in manufacturing heavy trucks, buses, and engines for marine and industrial use. Our Scania Super engine is the most fuel-efficient on the market, meeting high-performance demands. A critical aspect of assembly is ensuring the cleanliness and integrity of engine components, as particle contamination can severely impact performance and longevity. The assembly process requires precision, with each component meeting strict quality standards. Even minor contamination can cause engine failure. Traditional crash routines involve disassembly, disrupting operations and increasing costs.

A thesis project with Scania offers excellent networking opportunities, with many employees starting their careers this way.

Background
The engine assembly line is divided into basic engine and final assembly. Along the line there are various pre assembly stations. In the connecting rod pre-assembly process, the rod is split into two separate parts which results in open surfaces where loose particles are present. in the subsequent process, the connecting rod is exposed to various impacts, shocks and vibrations, which may lead to particles falling off which can affect the degree of cleanliness. This introduces a risk of particle contamination, which in turn can lead to severe engine failures such as seizure or breakdown. To ensure the highest possible quality and reliability in the assembly process, a deeper understanding of these mechanical influences throughout the process is required.

Project Constraints / Practical information
The thesis work will be conducted on-site in Södertälje with supervision from DE Engine Assembly.
You will have access to advanced measurement equipment and the opportunity to collaborate with experts in production and quality assurance.

Target
The expected outcome of the thesis is a detailed mapping of the current process flow, providing a clear understanding of how the connecting rod is handled and affected during pre-assembly and assembly. This will be supported by a quantitative analysis of the shocks, impacts, and vibrations that occur throughout the process. Based on the findings, the study will present recommendations aimed at reducing both contamination risks and mechanical stress on the components. Finally, the work will include a benchmarking report comparing corresponding assembly lines within the Traton Group, highlighting differences and potential areas for process improvement and standardization.

Assignment
The thesis work includes:

  • Process mapping of the current handling of connecting rods within DE Engine Assembly in Södertälje
  • Measurement and analysis of shocks, impacts, and vibrations at different stages of the process
  • Benchmark - Comparison of vibration and handling units across Traton Group's engine assembly lines (Scania, MAN, and International)
  • Document findings and propose an implementation framework for production use.
