Great American Inc. Aftertreatment Technical Training (East Dublin, GA)

Learn diesel aftertreatment basics with Skyline HDD—DPF, DOC, SCR operation, failures, and maintenance to prevent emissions system issues.

Join us for an in-depth Aftertreatment Technical Training presented by Skyline HDD, designed for technicians, parts professionals, fleet managers, and anyone working with modern diesel engines. This hands-on educational session will break down the fundamentals of today’s diesel aftertreatment systems and provide practical insights into how these systems function, why they fail, and how proper maintenance can prevent recurring issues.

Modern emissions systems have dramatically changed how heavy-duty engines operate. In this class, Skyline HDD will walk through the evolution of diesel aftertreatment, explain why these systems were introduced, and provide a clear mechanical understanding of the key components that keep trucks compliant and running efficiently.

Participants will gain valuable knowledge about how major aftertreatment components operate together, including the DPF (Diesel Particulate Filter), DOC (Diesel Oxidation Catalyst), and SCR (Selective Catalytic Reduction) systems. The training will also cover common failure points, diagnostic perspectives, and maintenance practices that can reduce downtime and costly repairs.

Whether you’re looking to strengthen your technical knowledge or better support customers and fleets dealing with emissions-related issues, this session provides practical, real-world insight from industry experts.

Training Topics Include:

• The history of diesel aftertreatment and how emissions regulations shaped today’s systems
• Why aftertreatment systems became necessary in modern engines
• A complete aftertreatment system overview
• Component breakdown of major system parts
• How the DPF, DOC, and SCR systems function from a mechanical standpoint
• How the industry has evolved and how engine operation has changed
• New ways to approach aftertreatment failures and recurring issues
• How preventative maintenance can reduce common system problems
• Understanding how and why each component fails

This training is an excellent opportunity to expand your knowledge, ask questions, and gain a deeper understanding of the systems that power today’s heavy-duty trucks.

Who Should Attend:
Technicians, diesel mechanics, fleet maintenance personnel, parts professionals, service managers, and anyone working with heavy-duty diesel equipment.
