Fundamental Concepts of Turbocharging Modern Engines: Current Practices and Trends WB1858

Turbocharging is rapidly becoming an integral part of many internal combustion engine systems. While it has long been a key to diesel engine performance, it is increasingly seen as an enabler in meeting many of the efficiency and performance requirements of modern automotive gasoline engines.

This web seminar will discuss the basic concepts of turbocharging and air flow management of four-stroke engines. The course will explore the fundamentals of turbocharging, system design features, performance measures, and matching and selection criteria. Both spark ignition and diesel engine systems will be discussed as well as the impact of different applications. It will discuss the interaction between turbocharging and engine systems and the impact on performance, fuel economy and emissions. Developments in turbocharging technology will also be discussed.

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
  • Recognize potential issues such as packaging, noise, driveability, reliability, and durability
  • List the latest developments in turbocharging technology and their attributes

Who Should Attend
This four-hour course will be beneficial to powertrain development engineers, component development engineers, engineering managers, product planners, service engineers, and those developing product strategies. 

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).

Although WebEx Training Manager will automatically launch when you join the web seminar, you or your system administrator are encouraged to download the plug-in in advance to help ensure successful setup. Click here, then follow the onscreen instructions.

Multiple Seat Discount - Does your company have a group of employees who need this course? Register one individual at the appropriate member or list price, then register additional employees at half off the list price. Registration by phone with SAE Customer Service is required to take advantage of this discount. Register all individuals at the same time or mention the confirmation number for the first registrant. The offer is good for only the same web seminar offering. All registrants will receive a personal account and opportunity for CEUs.

If you cannot attend, you may register a substitute in your place or transfer your registration to a future offering. A full refund is issued if you notify SAE at least 14 days prior to web seminar start date. If canceled less than 14 days prior, the full fee is charged. For $50, you may process a one-time transfer to a future offering within one year of canceled web seminar. Canceling may reduce group discounts.
