Engine Exhaust Aftertreatment Aging

See upcoming dates

Course Overview

Although the concept of internal combustion engine exhaust aftertreatment has been around since the 1950’s, vital improvements are made daily.  Continued emission regulations place emphasis on engine aftertreatment systems.  Upon completion of this course, learners will:

  • Have a foundation in the fundamentals of automotive catalysis for both spark-ignited gasolineand compression-ignited diesel engines.
  • Be able to describe how various anatomy of an exhaust aftertreatment component ages.
  • Understand the thermal, chemical and physical modes of deactivation in multiple engine designs.
  • Be armed with regeneration methodologies to counteract deactivation modes.
  • Gain a basis for accelerated aging for both gasoline and diesel catalysts.

Ultimately, this course will arm learners with critical knowledge of exhaust aftertreatment aging for both spar and compression ignited, internal combustion engines.

Who Should Attend?

Those wanting to gain deeper knowledge on exhaust aftertreatment applications, impacts, considerations and design. Learners seeking a deeper look at both spark-ignited and compression-ignited catalysis in automotive applications.  The content in this intermediate course appeals to engineers, engineering students, ICE enthusiasts and management responsible for overall aftertreatment design.

Instructors

Scott Eakle

Mr. Eakle is experienced in many areas of engine exhaust aftertreatment research and development and integration of such systems with engine management systems. Project work has included the development, modeling, evaluation, and integration of various aftertreatment systems for both gasoline and diesel applications, including particulate filters, Selective Catalytic Reduction (SCR), oxidation catalysts, as well as combined technologies such as SCR on filter. Mr. Eakle has derived numerous accelerated aging protocols for gasoline, CNG, and diesel aftertreatment devices that replicate real-world deactivation mechanisms. Modeling efforts include prediction of urea derived deposits in SCR systems. Mr. Eakle has commissioned numerous test stands capable of completing various forms of aftertreatment performance and durability studies. He has also set up controls on engines and burner systems to demonstrate accelerated aging of engine aftertreatment systems. Mr. Eakle also manages the division burner activities that cover aftertreatment durability testing and evaluations on SwRI’s ECTO-LabTM burner system. In addition to aftertreatment evaluation activities, Mr. Eakle is currently managing the Advanced Combustion, Catalyst and Aftertreatment Technologies (AC2AT) consortium.


While attending Colorado State University (CSU), Mr. Eakle gained a strong understanding of aftertreatment systems used in diesel applications. His research focused on a method to use non-thermal plasmas (NTP) in reducing NOx emissions for mobile and stationary lean burn engines. During his time at CSU, Mr. Eakle commissioned an NTP aftertreatment research facility which included an engine capable of being accessed and controlled from anywhere in the world through a webpage. He also designed and fabricated an NTP aftertreatment system for this facility that was able to achieve NOx reductions greater than 90%.


PUBLICATIONS: In his tenure with SwRI, Mr. Eakle has co-authored and presented 11 papers for the Society of Automotive Engineers in both the United States and Japan.
