With 2027 emissions regulations approaching, diesel aftertreatment systems will face significantly tighter NOx standards and more demanding operating conditions. These changes will place increased pressure on Selective Catalytic Reduction (SCR) systems to perform with greater precision and reliability. At the same time, deposit formation within SCR systems is emerging as a critical challenge that can impact vehicle uptime, maintenance costs, and emissions compliance.

This session will explore how the 2027 regulatory landscape is reshaping DEF performance expectations, why deposit prevention is becoming the next major frontier in SCR reliability, and what the aftermarket must understand to support fleets and customers. Attendees will gain insights into the causes of SCR deposits, how they affect system efficiency, and the innovations being developed to help ensure long-term emissions performance.
