“We’ve seen a dramatic shift with our valve technology since its introduction just three years ago,” said Tim Jackson, executive vice president and chief technology officer, Tenneco. “Tenneco’s latest generation valve has evolved to a modular, scalable design that is lightweight, can be easily packaged to fit within any engine architecture and offers on-demand customization, which provides significant cost and time savings for customers. Additionally, the valve can accommodate exhaust temperature specifications up to 750°C for EGR applications, which enables efficient NOx reduction – even with highly loaded engine conditions and high return flow rates.”
Tenneco’s latest generation valve features a dynamic flap control designed to generate optimal pressure conditions for efficient EGR and also provides fail-safe operation. The actuator is interchangeable using a simple mounting concept without any loose interface components and the valve’s flexible actuator orientation allows for simple installation in any engine control environment, without the need to change parts.
The valve delivers important acoustical benefits as well. Whether during engine start or while idling, the flap minimizes internal leakage, which helps to optimize sound quality. The electronically controlled variable flap remains closed during normal driving conditions for a quieter ride and opens during harder acceleration, creating lower backpressure, higher attenuation and more engine power for maximum efficiency.
“Tenneco’s new valve design serves as another important example of how our emissions technologies serve as enablers for improving fuel efficiency and helping customers meet important emissions regulations like EU6c, while maximizing engine performance,” Jackson said. “In the future, we’ll continue to see valve technology evolve into hotter areas of the vehicle and we are already in development with valves that provide exhaust heat recovery solutions to address that need.”
