Tackling SCR Fouling in Marine Engines: Causes, Consequences, and Effective Remedies
Selective Catalytic Reduction (SCR) systems are essential for reducing nitrogen oxide (NOₓ) emissions in marine engines, particularly under strict regulations. However, fouling issues can arise, especially during low engine load operations, affecting performance and increasing maintenance costs. This article discusses the causes of fouling and preventive measures for optimal SCR functioning.
