Powertrain Systems

The Delphi Dual Diesel Electronic Throttle Control is designed to control or regulate the intake manifold pressure of a diesel engine to increase rates of exhaust gas recirculation (EGR) flow. It also includes a mechanism to enable intake air to by-pass the intercooler allowing particulate trap regeneration. Customized mounting interfaces are available.

 

 

Benefits

• Accurate manifold flow control can achieve high EGR flow rates with minimal system effect
• Built-in valve to by-pass the intercooler allows regeneration of the particulate trap
• Permits low minimum EGR flow for smooth engine shutdown
• Non-contacting sensor provides improved reliability and durability
  

Typical Applications

The principal application for the Delphi Dual Diesel Electronic Throttle Control is for light duty high-speed engines.

Performance Advantages

The Delphi Dual Diesel Electronic Throttle Control offers manufacturers a number of functional advantages versus systems without manifold vacuum regulator valves and performance advantages over systems with pneumatic activation technologies. Some of these advantages include the ability to accurately regulate the manifold vacuum and to accurately repeat – and hold – any given position of flow. Its switching capability provides the advantage of fine control over the charge temperature allowing particulate trap regeneration to occur over a wider range of engine conditions compared to conventional technologies. This function can also be achieved with a separate by-pass valve. The Delphi Dual Diesel Electronic Throttle Control provides a packaging alternative for the separate by-pass valve.

The Delphi Advantage

Delphi is actively involved in the development of advanced diesel technologies to help manufacturers meet stringent emissions standards and to help enhance fuel economy. Delphi designs and supplies complete diesel engine management systems for light duty, medium duty, and heavy duty applications including injection systems and electronics. Delphi has six diesel design and engineering centers located in Europe, Asia, North America, and South America, and 11 diesel manufacturing facilities in eight countries enabling exception on-time delivery.
