BorgWarner Turbo & Emissions Systems developed an exhaust gas recirculation (EGR) valve enabling heavy commercial vehicles to comply with emissions standards. The electric butterfly EGR valve features responsive control, high flow capability, improved sealing, and resistance to exhaust soot and condensation. The torque from a high-strength brushless dc motor is transferred by a two-stage gear train, which opens the valve to control the flow of exhaust gas back to the air intake system, improving power-to-weight and durability in harsh environments. The motor’s sensors provide feedback to a closed-loop control system to position the valve and control the recirculated exhaust gas. Stainless steel components improve heat and corrosion resistance, while the valve design ensures low leakage and reliable operation within diesel exhaust systems.
