Diesel Engine Emissions and Aftertreatment Systems
Improve your understanding of diesel aftertreatment as it relates to product design, system development and environmental compliance. This course will provide members with a high-level system overview and deep dive into the details of component performance.

Introduction to Emissions Formation and Aftertreatment for Gasoline Engines
ETTN members will learn how regulated emissions are formed within a gasoline engine, what to consider if you fail and emissions test, and how aftertreatment systems work during this webinar. Hear Robert Prucka, Associate and Kulwicki Professor of Motorsports Engineering at Clemson University, discuss common issues associated with the test cycle and provide insight based on his technical expertise and real-world experiences.

A Practical Approach to Emissions Calibration and Compliance
As the industry focuses more heavily on improving emissions along with performance, companies need to know how to improve testing procedures and results, as well as efficiency. Hear Stephen Ruiz from the Automotive Consulting Services (ACS) as he shares how to go through the process of emissions. Ruiz has extensive experience with powertrain calibration for internal combustion engines and transmissions to meet specific engineering requirements.

ADAS Technology and Its Impact in the Aftermarket
ADAS technology is included on virtually every part of a new vehicle and it's impossible to avoid. Regardless of the product being developed, aftermarket product developers, engineers and programmers must understand ADAS technology and learn to work around it. Hear industry experts as they explain the unknowns surrounding ADAS technology, including modifications, repairs, calibration, and testing, and details on the ADAS Research Center that will be available to members at the new SEMA Garage Detroit facility.   

Engine Cylinder Pressure Analysis
Discover what tools are available to help diagnose cylinder pressure issues, how to read and interpret the data and what you need to adjust to get the most out of your engine. During this session, Gary Patterson, R&D engineer at Roush Yates Engines, shares details about cylinder pressure measurement, common abnormal events, and how to optimize engine cylinder pressure analysis for peak performance.
