Fundamental Concepts of Turbocharging Modern Engines: Current Practices and Trends

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.

What Will You Learn

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

Is This Course For You
