WebExhaust gas recirculation (EGR) is the most common technology to reduce nitrogen oxides (NOx) emissions on diesel internal combustion engines (ICE). EGR takes exhaust gases from the exhaust manifold and … 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 ...
