Built for Urban Duty: Dennis Eagle Cummins DEF Head Unit – Reliable Emissions Control
What is it?
The Dennis Eagle Cummins DEF Head Unit is a key component in the Selective Catalytic Reduction (SCR) system used in Dennis Eagle vehicles powered by Cummins ISB and B6.7 engines. It regulates the injection of Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce harmful nitrogen oxide (NOx) emissions. Equipped with sensors for temperature, fluid level, and pressure, it ensures accurate dosing and consistent emissions compliance.
