Hong Kong, 10 March, 2015 — Johnson Electric today announced a new brushless motor dosing module for Diesel Exhaust Fluid (DEF) used in the Selective Catalytic Reduction (SCR) process in heavy duty diesel engines. The Johnson Electric dosing modules are custom designed for both air assisted and airless DEF systems used in trucks, bus, and off road vehicles. Johnson Electric’s brushless motor and control technology provides the industry’s widest speed range to cover variable urea dosing requirements. Integrated motion control enables exact amounts of urea to be delivered to the selective catalytic reduction system for maximum NOx reduction.
“DEF dosing accuracy is critical for SCR systems to reduce NOx emissions,” said Jim Dick, Johnson Electric’s senior vice president of Strategic Marketing. “ Johnson Electric is working with global SCR providers and engine makers to meet NOx reduction targets,” he added.
