When I do a relearn procedure with Xentry soot content is still same and fill level, how is this two value calculated. Starting in 2008, Ford began using Diesel Particulate Filters (DPF) on their diesel trucks. At this stage the The ECM will start the Regeneration process of the DPF if the soot load exceeds a calibrated value. nobody i know can help me. In other words, the amount of ash equals the amount of soot at the maximum allowable soot load limit of 6 g/L. The filter is cleaned by burning off all the diesel particles (soot). 5) If the coil and engine management light is on with a loss of power, ‘limp home mode’ will engage with a maximum of 3000 RPM and the fault code will read ‘DPF soot loading too high management of the DPF regeneration via two main ways: • Delayed injection timing and two post injections. It has a series of small, honeycomb-shaped openings covered in palladium or platinum. The parameter should be less than 5 grams. I cleared the Under normal engine operation, the DPF collects soot and other particulate matter. The gasses are able to escape through the sidewall of these cells, leaving behind solid particulate matter in the form of residual soot and ash. This varies with each vehicle manufacturer from Ford at 75,000 miles to BMW at 150,000. This was like I expected it to be. Most SiC DPFs can handle between 6 - 8 grams of soot PER LITER before pressure gets too high and they want to regen. You may notice that there are two soot level readings in GDS2. Although DPF filters lead to cleaner emissions, the soot that builds up within them must be cleaned out. Sep 19, 2016 · These readings and an estimate of the exhaust flow rate thru the dpf are used to estimate the amount of soot in the dpf. The whole reason the Diesel Particulate Filter came along was to clean up the diesel car image (Euro 5 Emissions, 2009). 0 Scale Factor – x1 Unit Type – Grams/Liter Equation – ((A*256)+B)*(100/65535)-1 OBD Header – 7E0 EGT Post Turbo – EGT 11 – On the scanner data, it’s recording soot levels of 400% in the DPF, even after cleaning. The DPF differential pressure sensor and fuel burned increase in increments of 1 gram. stop and go), etc etc. When a clogging threshold is reached (18 grams), the engine’s computer will trigger active regeneration. Beginning around 2007, school buses were equipped with diesel particulate filters, aimed at collecting soot to decrease exhaust emissions. One uses the differential pressure sensor to calculate the soot in the DPF and the other uses other engine data. • Developed single antenna RF system and demonstrated high level of accuracy for DPF soot level measurements • Demonstrated combined DPF soot AND ash measurements • RF transient response well-correlated with AVL micro-soot sensor • Demonstrated fast sensor response < 1 second • Evaluated RF performance over 380,000 mile equivalent DPF The NO 2 level at the filter outlet can vary from about 20% to as much as 60% of the total NOx.
