Automotive Powertrain Laboratory

Location: City Campus Esslingen, building 2
Laboratory Exercises and Projects
Laboratory Exercises and Projects
Laboratory work in the Bachelor degree programmes:
- Emissions of a spark ignition engine: Cold start and lambda variation – raw emissions and exhaust gas post-treatment
- Efficiency/losses: speed, load and ignition point variation
- Charge cycle in the spark ignition engine: scavenging and internal residual gas variation
- Emissions and noise of a diesel engine: variation of fuel injection timing, exhaust gas recirculation rate and pilot injection
Laboratory work in the Automotive Engineering Master programme:
- Thermodynamic analysis on the whole engine
- Optical investigations on a single cylinder engine
Student projects and final theses:
Project work is undertaken in the 4th and 6th semesters. The Lab Automotive Powertrain regularly advertises projects which it supervises itself.
- H2 projects
- Cooling circuit in the loop
- Motor simulation: 3D CFD of charge cycle and injection processes
- Projects in collaboration with the Rennstall Esslingen racing car project
- Develop a concept for a hydrogen infrastructure on the test stand
- Develop concept strategies for hydrogen internal combustion engines and fuel cells
The Lab Automotive Powertrain also supervises projects and final theses which form part of the Master programme:
- Combustion analysis on the thermodynamic single cylinder research engine
- Research and development relating to the combustion process in the spark-ignition engine for hybrid car applications
- Gas discharge anemometry: development of a method to measure the internal cylinder flow
