CNH Selective Catalytic Reduction (SCR) – Tier 4a Emission Strategy

9,99

This factory training manual provides a complete overview of the Tier 4a SCR system used in CNH NEF engines, detailing how nitrogen oxides (NOx) and particulate matter (PM) emissions are reduced through chemical aftertreatment.

It explains emission regulations, pollutant formation, AdBlue (DEF) properties, SCR operation, and system diagnostics. The presentation includes flow diagrams, sensor layout, hydraulic DEF circuits, and maintenance schedules for filters and injectors.

The system works by injecting urea-based DEF into the exhaust stream, converting harmful NOx into harmless nitrogen and water through a catalytic reaction.
