Turbocharging for Fuel Economy and Emissions WB1018

Turbocharging is already a key part of heavy duty diesel engine technology. However, the need to meet emissions regulations is rapidly driving the use of turbo diesel and turbo gasoline engines for passenger vehicles. Turbocharged diesel engines improve the fuel economy of baseline gasoline engine powered passenger vehicles by 30-50%. Turbocharging is critical for diesel engine performance and for emissions control through a well designed exhaust gas recirculation (EGR) system. In gasoline engines, turbocharging enables downsizing which improves fuel economy by 5-20%.

This web seminar will explore turbocharging for gasoline and diesel (heavy and light duty) engines, including the fundamentals of turbocharging, design features, performance measures, and matching and selection criteria. It will discuss the interaction between turbocharging and engine systems and the impact on performance, fuel economy and emissions. Developments in turbocharging technology such as variable geometry mechanisms, two-stage and sequential (series & parallel) turbocharging, EGR including low pressure loop, high pressure loop and mixed mode systems and novel turbocharging systems will be described using figures and data.

Learning Objectives
By participating in this web seminar, you will be able to:
  • Identify the basics of how a turbocharger works, how to measure the appropriateness of a turbocharger, and how to select and match a turbocharger to the needs of your powertrain
  • Estimate the impact of turbocharging on performance and emissions
  • Anticipate potential issues such as packaging, noise, driveability, reliability, and durability
  • List the latest developments in turbocharging technology, their impact on engine performance and emissions, and the use of turbocharging world-wide

Who Should Attend
This course will be beneficial to powertrain development engineers, component development engineers, engineering managers, product planners, service engineers, and those developing product strategy. Heavy duty diesel engine development engineers may find the course helpful by increasing their knowledge of turbocharging and EGR systems.

To get the most out of this course, you should have a familiarity with automotive engines. A Bachelor's degree in Engineering is desirable.

Registration Information
Registration for this live web seminar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access and a telephone. The fee includes one connection to the conference calls (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the presentations, supplemental materials, and assignments.

Registrations will be accepted until 5:00 p.m. the day before the start of the web seminar, but early registration is encouraged to allow for pre-course set-up and instructions.

*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this web seminar. If your country is not listed, you may still connect using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).
