POWERTRAIN SYSTEMS Delphi Dual Diesel Electronic Throttle Controls Delphi Dual Diesel Electronic Throttle Controls regulate the intake manifold pressure on diesel engines to help increase exhaust gas recirculation (EGR) rates. They also include a mechanism to enable intake air to by-pass the intercooler allowing particulate trap regeneration. The valves can also provide low minimum flow for smooth diesel engine shutdown. 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 Achieves low minimum flow rates for smooth engine shutdown, and minimized noise, vibration and harshness (NVH) Non-contacting throttle position sensor technology provides improved reliability and durability Delphi Dual Diesel Electronic Throttle Control Valve Typical Applications The principal application for Delphi Dual Diesel Electronic Throttle Controls is for light duty high speed diesel engines to contribute to reduced NOx emissions and particulate trap regeneration. Performance Advantages Delphi Dual Diesel Electronic Throttle Controls offer 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 manifold vacuum and to accurately repeat — and hold — any given position of flow. Their 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. Delphi Dual Diesel Electronic Throttle Controls provide a packaging alternative for the separate by-pass valve.
