Learning Outcomes: After successfully completing this unit the student will be able to:
* Describe the aerodynamic and thermodynamic theory that relates to centrifugal compressors and turbines in a turbocharger.
* Discuss the parameters that define turbocharger and supercharger performance.
* Explain how the performance of turbochargers is measured in a gas stand facility.
* Describe turbocharger performance map characteristics and critically analyse how these relate to the interaction and matching with the engine.
* Understand the modelling methods commonly used to assess performance of boosted engines and critically assess their limitations.
* Explain the importance of modern boosting systems in addressing the environmental issues of transportation
* Discuss future trends in turbocharger and supercharger technology.

Aims: To provide knowledge and understanding of turbocharging and other boosting systems applied to internal combustion engines. To analyse turbocharger and supercharger interactions, performance and component design.

Skills: Problem solving; numeracy; working independently; written communication.
