Turbocharging Internal Combustion Engines

See upcoming dates

Course Overview

Patented over 115yrs ago, Turbochargers altered the path of Internal Combustion Engine Design. In the very first application, shipping vessels were changed forever when power was increased from 1750hp to 2500hp utilizing the original twin diesel engines. Upon completion of this course, learners will

  • Understand the objectives of turbocharging for diesel and spark-ignition engines.
  • Become familiar with key terminology associated with features of turbo design and distinguish between fluid processes in the turbine and compressor sections.
  • Be introduced to turbocharger operational limits and walk-through efficiency calculations.
  • Gain a familiarity with engine-compressor matching along with turbocharger sizing, selection and control.

Ultimately, this course will arm learners with powerful knowledge pertinent Turbocharger considerations in Internal Combustion Engine Design.

Who Should Attend?

Anyone wanting to gain deeper knowledge on Turbocharger applications, impacts and considerations in Internal Combustion Engine Design.

Kevin Hoag

Mr. Hoag has over 40 years of experience in diesel and gasoline engine development, both in industrial and academic environments, and is a Fellow of the Society of Automotive Engineers. He holds the position of Institute Engineer, the highest technical level position at SwRI and currently chairs SwRI’s Advisory Committee for Research (ACR). His experience is wide ranging and includes both diesel and spark-ignition combustion, engine performance development, emission control, engine layout and balance, casting, forging and materials, structural fatigue analysis, air handling, cooling, and lubrication systems. He also has extensive experience with customer interaction, engine application and service, and engineering education.

Mr. Hoag’s work experience includes two years in automotive heat exchanger development (Modine Mfg.), 16 years in diesel engine development (Cummins, Inc.), and 14 years in engineering education and engine research (University of Wisconsin) all prior to joining SwRI in 2013. He continues to hold an appointment at the University of Wisconsin, teaching one graduate course by distance each semester.

Specific highlights of Mr. Hoag’s technical contributions include development of explicit formulation for Second Law analysis of IC engines, creation and management of the Heat & Fluids group at Cummins, Inc. and Founding Director and Lead Developer of the Master of Engineering in Engine Systems (MEES) Program at the University of Wisconsin.
