Hotel & Travel Information
Public awareness regarding pollutants and their adverse health effects has created an urgent need for engineers to better understand the combustion process as well as the pollutants formed as by-products of that process. To effectively contribute to emission control strategies and design and develop emission control systems and components, a good understanding of the physical and mathematical principles of the combustion process is necessary. This seminar will bring issues related to combustion and emissions "down to earth," relying less on mathematical terms and more on physical explanations and analogies.
Learning Objectives
By attending this seminar, you will be able to:
- Identify and describe the important processes in combustion and emission
- Identify the formation mechanisms and reduction strategies of pollutant species in combustion systems
- Recognize the effects of engine design and operating conditions on combustion and emission
- Explain the technology and the logic behind after-treatment of pollutants
- Identify the underlying laws and principles used in combustion and emission black-boxed computer programs
- Explain the role chemical kinetics plays in the design of low-emission combustion systems
- Identify design trade-offs between increasing engine performance and maintaining low emission characteristics
Who Should Attend
Engineers working on the design of combustion engine components, software development and application for modeling of thermal-fluid, combustion and emissions processes, and those working on the reduction of harmful pollutants emissions will find this course valuable.

Instructor(s): Bruce Chehroudi
Dr. Chehroudi is currently a Principal Scientist at the Engineering Research Corporation Inc. He has been a Chief Scientist at Raytheon STX (formerly Hughes Aircraft STX) and is a former Professor of Mechanical Engineering, specializing in fluid mechanics and heat transfer, laser optical diagnostics, internal combustion engines, structure of sprays (their formation and combustion), gas turbine engines, furnace combustion, fuel injection issues (reciprocating, gas turbine, and rocket engines) and emission of pollutants. Dr. Chehroudi previously served as a Research Staff Member at Princeton Univ. where he engaged in experimental research in fluid mechanics and heat transfer of cold, vaporizing, and combusting sprays as well as characterization of turbulence in internal combustion engines using laser optical diagnostics. He was actively involved in the DISC (direct injection stratified charged) Engine Program, a cooperative project between the Department of Energy, General Motors Research Laboratory, Sandia-Livermore Combustion Laboratory, and Los Alamos Scientific Laboratory. Dr. Chehroudi established and directed an Engine Laboratory at the Univ. of Illinois where he conducted numerous research projects to investigate the formation of pollutants and heat transfer/fluid mechanical aspects of combustion occurring in internal combustion and gas turbine engines. He is a member of Ta Beta Pi and the recipient of several SAE awards including the Arch T. Colwell Merit Award, the Ralph R. Teetor Award, and the SAE Recognition Award. He has also received the SAE Forest R. McFarland Award in recognition of his efforts and leadership in contributions to the Continuing Professional Development Seminars. Dr. Chehroudi has taught courses in areas of internal combustion engines, thermodynamics, thermophysics of gas flows, combustion, and measurement system and has more than 70 publications in conferences, national and international journals.
