Tailored Emissions Control: Doosan Bobcat Cummins ISB 6.7L DEF Head Unit
What is it?
The Doosan Bobcat Cummins ISB 6.7L DEF Head Unit is a dedicated emissions component in the Selective Catalytic Reduction (SCR) system used with Cummins ISB 6.7L engines installed in Doosan Bobcat construction and utility machinery. It precisely meters Diesel Exhaust Fluid (DEF) into the exhaust stream to convert harmful NOx emissions into clean nitrogen and water. Integrated sensors continuously monitor fluid level, temperature, and pressure—ensuring accurate DEF delivery and reliable emissions system operation.
