WebJan 1, 2024 · For increased EGR flow at high engine loads, some diesels (such as the VW 2.0 liter common-rail TDI) also use a low-pressure EGR system. Low-pressure loop (LPL) EGR takes exhaust gases from the outlet of the diesel particulate filter and sends them into the turbocharger air inlet. LPL EGR may also incorporate a cooler to further decrease NOx ... WebOct 20, 2007 · Most light duty diesel engines use high-pressure EGR. And, the newer VW P-D engines are in fact throttled! The control strategy for the EGR valve opens the EGR valve fully first, but if the amount of EGR drawn in is still not sufficient, it closes the "throttle" to cause more EGR to be pulled through the EGR system.

WebApr 30, 2013 · Comparing these variables to the dual loop EGR system under constant boost pressure, approximately 8% of torque and 5% BSFC improvement were achieved except at high load conditions (case 4). For the optimized dual loop EGR system, 60% improvement of deNOx efficiency was achieved with increasing EGR rate through all the cases compared … WebDec 23, 2015 · There are TWO EGR valves on your car, two completely independent systems, a high pressure and low pressure. I assume you replaced the high pressure one, on the front of the engine, behind the throttle flap, attached to the intake manifold, as the other one is part of the EGR cooler and buried underneath the turbo on the back side of the engine. WebA high pressure (HP) EGR Valve is a very demanding application for dry running sealing solutions due to the close position to the exhaust tract.
