Auburn Hills, Michigan, January 25, 2011 – BorgWarner’s actuator technology powers its new electric exhaust gas recirculation (EGR) valve for the Cummins 11.9-liter and 15-liter engines, launched recently for various on-highway commercial diesel trucks. The combination of BorgWarner’s leading EGR valve and actuator technologies reduces emissions while offering durable and reliable operation in the harshest commercial diesel powertrain environments.
“Today’s commercial and industrial diesel engines require state-of-the-art EGR systems to lower the combustion temperatures that produce harmful NOx emissions,” said Dr. Thomas Waldhier, President and General Manager, BorgWarner Emissions Systems. “As emissions standards in this market segment continue to become more stringent, we anticipate demand for our advanced EGR systems to grow significantly.”
Designed to reduce nitrogen oxide (NOx) emissions, BorgWarner’s new electric butterfly EGR valve features precise and responsive control combined with high flow capability, excellent sealing, corrosion resistance and reliable operation in the most severe operating environments. All major components, including the housing and valve, are built with stainless steel for durability. The butterfly EGR valve is driven by BorgWarner’s compact brushless actuator. With a robust and reliable gear train, the actuator delivers high operating torque, fast response and proven durability in a small package. Sensors within the compact brushless actuator provide feedback to a closed-loop control system to position the butterfly EGR valve and ensure precise control of recirculated exhaust gas. With electric actuation, smart electronics and proven reliability, the compact brushless actuator can be used in a variety of powertrain applications. It is available in both smart and non-smart versions and can be water-cooled for extreme temperature applications.
