Diesel Engine Noise Control
I.D. # WB1041 Duration 4 Hours
This web seminar provides an in-depth overview of diesel engine noise including combustion and mechanical noise sources. In addition, the instructor will discuss a system approach to automotive integration including combining sub-systems and components to achieve overall vehicle noise and vibration goals.
Learning Objectives
By participating in this web seminar, you will be able to:

  • Identify and analyze commonly occurring diesel engine noise sources
  • Understand how analytical and experimental techniques can be used to solve diesel noise issues
  • Prescribe appropriate noise control analysis and solutions for specific diesel engine NVH issues

Who Should Attend
This course is ideal for those want to understand the root causes of many diesel engine noise issues, and how to use this understanding to better diagnose and control diesel engine-related noises.
Those intending to take this web seminar should have at least a Bachelor's degree in engineering, or equivalent, and be familiar with basic engineering mechanics and vibrations.

Instructor(s): Thomas Reinhart
Tom ReinhartThomas Reinhart is a Program Manager for NVH in the Engine, Emissions, and Vehicle Research division of Southwest Research Institute. Previous roles include Senior Manager for NVH at Visteon Chassis Systems, where Mr. Reinhart was responsible for the NVH analysis and development of axles, driveshafts, and power steering systems. From 2001 to 2004, he was NVH Program Manager at Roush Industries, Inc. where he was responsible for NVH testing and development of diesel and gasoline engines, as well as transmissions, axles and accessories. Diesel fuel system noise was a special focus of this work. Prior to Roush, he was Director of Noise & Vibration Technology at Cummins, Inc. Mr. Reinhart has been involved in solving noise and vibration issues in engines, as well as in a wide variety of engine applications, including pickup trucks, heavy duty trucks, construction equipment, and marine. Mr. Reinhart has developed noise reduction features for diesel engines, four of which have been patented. He has published 15 technical papers on Powertrain NVH topics. Mr. Reinhart received his B.S. and M.S. in mechanical engineering from Purdue University. He also spent a year studying automotive engineering at the Technical University of Hannover, Germany. His master's thesis focused on the application of acoustic intensity measurements to diesel engines.
