DEF dosing maximizes NOx reduction

A new brushless motor dosing module suits air-assisted and airless diesel exhaust fluid systems used in Selective Catalytic Reduction treatment of heavy-duty diesel 56 DEF 400engine emissions. The motor and control technology provides a wide speed range to cover variable urea dosing requirements. Integrated motion control enables exact DEF amounts to be delivered to the SCR for maximum NOx emissions reduction. — Johnson Electric, www.johnsonelectric.com
