and multi-stage turbocharging, high and low pressure loop EGR systems, assisted turbocharging and turbocompounding are discussed. Students will have the opportunity to perform hands-on exercises to gain an appreciation of parametric effects in a wide range of engines. **Participants are expected to bring a laptop computer, with Excel, to the seminar for class exercises. Learning Objectives By attending this seminar, you will be able to: • Describe the thermodynamic principles governing the turbocharging of internal combustion engines • Articulate the critical contribution of turbocharging to modern day diesel engine performance and emission control • Determine the possible benefits of turbocharging for specific gasoline and heavy and light duty diesel engine applications • Estimate the appropriate turbocharger characteristics for specific applications based on engine system requirements • Describe the limitations of current technologies and evaluate new technologies and their possible role in meeting future engine/vehicle system challenges • Apply the basic principles of matching turbocharger with engine and optimizing overall system for desired performance and emissions Who Should Attend This seminar is designed for engineers, managers, and other technical personnel from OEM and support industries concerned with the design and development of optimized diesel and spark ignition engine systems, including performance, fuel economy and emissions for passenger car, light truck and heavy duty engines. Some background in thermodynamics, IC engine performance and emissions will be helpful. Individuals who need more background should consider attending SAE seminar “Diesel Engine Technology” (ID# 93014) or “The Basics of Internal Combustion Engines” (ID# C0103).

Turbocharging Internal Combustion Engines 3 Days | Classroom Seminar I.D.# C0314 The need to control emissions and maintain fuel economy is driving the use of advanced turbocharging technology in both diesel and gasoline engines. As the use of diesel engines in passenger car gasoline and diesel engines increases, a greater focus on advanced turbocharging technology is emerging in an effort to reap the benefits obtained from turbocharging and engine downsizing. This seminar covers the basic concepts of turbocharging of gasoline and diesel engines (light and heavy duty), including turbocharger matching and charge air and EGR cooling, as well as associated controls. The limitations and future possibilities of today’s systems will be covered, as well as details on how emerging technologies will impact engine/vehicle performance. The seminar’s primary focus is on the turbocharger-engine interface (subjects such as matching, benefits, limitations, and new technologies) rather than detailed turbocharger aerodynamics and design. Advanced technologies such as variable geometry
