BorgWarner is a provider of engineered components and systems for vehicle powertrain applications. 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.

Designed to reduce nitrogen oxide 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.

Thomas Waldhier, president and general manager of BorgWarner Emissions Systems, said: “Today's commercial and industrial diesel engines require state-of-the-art EGR systems to lower the combustion temperatures that produce harmful NOx emissions. As emissions standards in this market segment continue to become more stringent, we anticipate demand for our advanced EGR systems to grow significantly.”

Will the new EGR valve reduce nitrogen oxide emissions?
