Simulation of Turbocharged IC Engines – Detroit

This course will focus on the simulation of turbocharged IC engines using GT-POWER. It has been designed for automotive engineers who have already experience using GT-POWER to simulate engines, want to learn how GT-POWER models turbochargers and want to learn techniques that improve the speed and results of models. The class will include interactive work in GT-POWER using a model provided by GTI. In addition, the class will be flexible, allowing the participants to select among certain topics, so they have an opportunity to learn about topics that relate to their work.

1. Modeling turbocharged engines using GT-POWER
   • Modeling of turbochargers
   • Map fitting and extrapolation
   • Intercooling methods: simple, semi-predictive and predictive
   • Convergence
   • Transients
2. Control of a wastegate to meet a desired boost pressure (exercise)
3. Other potential turbocharging topics (to be decided by the participants)
   • Matching turbochargers to engines using TurboMapMatch
   • Using mean value cylinders to study advanced turbocharging concepts (two-stage, turbocompounding, e-boost, etc.)
   • CompressorSimple and TurbineSimple
   • Calibration of controls when more than one is present (e.g., wastegate and EGR)
   • Advanced map fitting and analysis techniques
   • Other topics proposed by participants
4. Open discussion (participants may pose questions to the instructor)

Participants are asked to send to Mr. Wanat ([email protected]) upon registration an e-mail listing the other topics in item 3 that they want to discuss. This will give Mr. Wanat enough time to prepare course material and exercises (if needed) for the selected topics.
