Norgren Air Intake Throttle Improves Emissions Control for Heavy-Duty Diesel Engines

Littleton, CO, May 11, 2013 --(PR.com)-- A robust air intake throttle from Norgren stands up to the demands of heavy-duty diesel engines while precisely regulating airflow so that emissions control systems operate at peak efficiency. Common techniques for reducing nitrogen oxides (NOx) and particulate matter or soot to meet 2013 EPA Tier IV Final Emissions Regulations include Exhaust Gas Recirculation (EGR), Selective Catalytic Reduction (SCR) and Diesel Particulate Filters (DPF). When these three are used in combination, managing the airflow is essential for boosting the EGR while maintaining high exhaust temperatures for maximum SCR and DPF efficiency.

Throttle technologies adapted from automobile gasoline engines often fall short of the long-term requirements in the harsh operating environment of heavy-duty diesel engines in commercial vehicles. Now Norgren, a global supplier of motion and fluid control solutions, has engineered air intake throttles specifically for these engines. The corrosion resistant design incorporates FKM seals, high temperature-range greases, steel gears, pressure die cast housings and a durable brushless electric geared motor. The machined flap meets tight tolerances inside the bore for precise sealing and is spring loaded to default to the open position as a failsafe. The brushless motor withstands vibration and high temperature to retain great precision over millions of cycles. The compact unit is available in multiple sizes to fit virtually any commercial vehicle design.
