Du et al.  proposed a method for estimation of the DPF soot load based on a DPF equivalent circuit model, with the diesel engine transient tests based on world harmonized transient cycle (WHTC. Discussion Starter · #1 · Jul 1, 2014. I loaded some new PID's into Torque and am monitoring DPF soot percentage, and soot grams/liter. Very shortly, within 1/4 mile of an active regen completing, I noted the following: Soot %: 29.1. Soot G/L: 0.5. After driving 40 miles of mixed highway/city driving, my readings are: Soot %: 74.3. Soot G/L: 1.3. 2017. 11. 1. · Antenna Calculator . FIND THE LENGTH OF A DIPOLE. FREQUENCY IN MHz. THE TOTAL LENGTH OF YOUR DIPOLE IS: IT WILL BE ON EACH SIDE. 3 ELEMENT YAGI . W4CLL Home Page. Last Edited: 10/6/12. 2012 Plant City Data Service. After the completion, I drove 20 km back home and checked the soot load: 10.4 g! I reset (once again) the DPF learned values, and ECU showed 0.0g soot load. Took the car to a 10km ride, during which the soot load value increased to 2.1 g. Just to be sure, I disconnected the Forscan and checked the value again - still 2.1 g. So apparently the.
Been searching high and low and cannot find info on how to use my OBDeleven to check the soot / ash load in the DPF. Would really, really appreciate if someone could point me in the right direction. Car is a 2010 Golf Sportwagen TDI, CJAA engine. ... 0 100 200 300 400 500 600 700 800 900 1000 DPF flow rate kg/h mBar double blower single blower.
So where does the calculate soot load and the measured soot load come from? ... there really isn't any soot in it?? 18:45:28 Group 241: DPF Soot load 90 ml Particle Filter Oil Ash Volume 50.1 Soot Load(g) Calculated ... at idle and as high as say 650 under acceleration. The other two (post turbo and somewhere else) were generally in the 300-350. My soot level was 44 to 45 grams when regen started when regen finished my soot grams were at 11 grams. This sounds a little high to me was wanting to see what others see after a regen . ... ( DPF ) Regeneration Functionality (1570, 1575, 1580, 1585) Status Detection. ... your Tractor. When the soot level reaches a certain threshold , usually. pinball history timeline. Audi Q7 3.0 TDI DPF Removal Fault Codes: P200200 Particulate Trap Bank 1-Efficiency Below Threshold P246300 Particulate Filter Restriction - Soot Accumulation Bank 1 ... Check Engine Light - On DPF Warning Light - On Coil Light - On Solution: DPF Removed and Software Re-Engineered to exclude DPF function from the Engine Control Unit (ECU).
The DPF outlet temp should stabilize roughly 50F less than the DPF inlet temp. If outlet temp stays above inlet temp, the DOC could be dirty or contaminated or the DPF could be damaged. They should run in the 1000-1100F range. You don't want to see exhaust temps above 1300F as it will start to melt things. The EURO5 is a bit more sophisticated and regens based on a soot level calculated with respect to various parameters, the main one seemingly being the DPF differential pressure. Thus the regen distance can change dramatically dependent on the actual soot load as estimated from the DPF differential pressure. Du et al.  proposed a method for estimation of the DPF soot load based on a DPF equivalent circuit model, with the diesel engine transient tests based on world harmonized transient cycle (WHTC.
Soot load 86% DPF load 59%- ... 5th Dec, long 300 mile run over weekend soot ld 66% <<<<<-----Looks like it may have done a successful regen-I don't think I have seen the last of my P244C friend. After all, it has never played up for past 6 years, when most of driving style has been similar. (mostly 10 mile non-motorway commute daily).
The DPF Soot Load Reduction Threshold is the level at which soot is released into the air during regeneration. This is necessary to prevent a regenerative cycle from occurring. It is crucial to maintain the correct O2 levels to improve the effectiveness of the DPF. To reduce the regeneration threshold, a DPF should be flushed periodically.
Sensors tell the brains in the car when the DPF is loading up, which then triggers a regeneration cycle to begin (which involves injecting extra fuel which heats up the exhaust system, including DPF, to burn off the soot that has collected in the system (usually the DPF – you can tell this is happening as there is a heat 'smell' the start as all the cr-p on the outside of the.
