soot level high regenerate dpf to prevent derate

When you click on links to various merchants on this site and make a purchase, this can result in this site earning a commission. regeneration request is ignored, engine performance will degrade and unplanned there is a serious concern about elevated exhaust gas temperatures occurring. Ever thought about starting a mobile repair shop? Basically, DPF as this acronym implies stands for Diesel Particulate Filter. 6 years of development. Regenerate dpf to avoid derate. Archived post. This is common among trucks with a lighter duty cycle, because soot accumulates while idling or going slowly through traffic. It went to 127% before regen. Rather than naturally occurring when the DPF reaches the high temperature on its own, the engine undergoes a process to increase exhaust heat and create a chemical reaction that generates the temperatures needed to oxidize particulate matter. Fault 1922 included troubleshooting steps that alerted users another fault on the vehicle would likely be fixed with a forced regen, leading to a high occurrence of necessary regens. Using an average diesel price of 2.42, that equates to $2,700-$4,043 in wasted fuel costs. Fullbay is made possible by an incredible group of people, staring with our leaders. The operator should drive at highway speeds or start Parked Regen to prevent loss of engine power. Required action: To avoid engine derate being vehicle to highway speeds to allow for an Automatic Regeneration or perform Parked Regeneration as soon as possible. In these cases, an active regeneration occurs. Your car performance will also suffer, and it might even emit more visible smoke from the exhaust than usual. In some cases, the DPF may need to be disassembled and cleaned manually. The ATS is made up of the Diesel Particulate Filter ('DPF') System and the Selective Catalytic Reduction ('SCR') System to reduce particulate and nitrogen oxide emissions. The main active components of all DPF filters are ceramic cell matter, based on Cordierite and silicon carbide ceramics. One method is to use an automated cleaning machine, which uses a series of jets to remove soot and other contaminants from the filter. In order for this to go away it will need to be reset with a pc or capable scan tool. Under active regeneration, triggered by a series of steps taken by the operator while the vehicle is stationary, the fuel doser ahead of the DOC in the system is engaged to bring temps up to 1,100-1,200 degrees to burn off soot. Over time, these particles can accumulate in the diesel particulate filter (DPF), which is designed to reduce soot levels by trapping the particles and burning them off in a process known as regeneration. The regeneration cycle must be performed while the By following this list, technicians can often correct the problem without the need to force a regen. temperature to burn off the particulate matter. We only included data when the associated fault was the only active fault code during the connection. Often shortened to "regen," a DPF regeneration is the act of the system burning off collected particulate matter and turning it into ash. Scan this QR code to download the app now. You guessed it: the diesel particulate filter is one more thing that must be tracked and maintained on a heavy-duty truck. The regeneration process occurs when the car is running at high speeds or when certain environmental conditions are met, such as air temperature and exhaust gas temperatures. The ECM then switches on an extra fuel injector that shoots fuel into the exhaust stream. operator with an advisory that a Recovery regen is required and the PTO will But over time, soot builds up in the DPF filter walls. How does it happen? Grow your business with a premium website, pay-per-click management, and more. regeneration to help with this process. I guess all I am saying in here is that the broader picture at the engine systems should be taken into consideration. . Privacy | Cycles Passive, Assist and Reset regeneration are automatic methods, and Watch for temperatures to raise (please note that during high soot load levels the DOC and DPF temperatures will be lower than normally expected to prevent cracking of the filter). regulations. If active regen requirements arent met or soot levels rise to a certain point, you may need to perform a forced regeneration. He recommends working in conjunction with a service facility to gauge where youre at on the need to clean, a matter of gauging the level of [exhaust flow] restriction in the DPF. At 130,00 miles, he suggests, flow test the filter. Engine regeneration is one new challenge related to T4F that increases downtime and can impact truck performance. A better life for shops leads to safer roads for us all. Level 2: (Amber light with DPF sign is flashing) Filter regeneration Necessary. reducing harmful emissions in order to comply with EPA-mandated Tier 4 That's why it's important to perform regular maintenance and inspections on your DPF in order to catch any problems early. Another way to determine whether your car has an issue with its DPF is to look for signs of excessive smoke from the exhaust. takes about 30 minutes). See label above visor. The substantial heat required for the regen renders the engine and aftertreatment system untouchable until it has time to cool down. Why would I run a forced DPF regen if my truck is not asking for one? I'm guessing miles are in the 3-400k? Heres what those percentages mean: Above Soot Load 78%: Reset regeneration If a In simple terms this is a canister where the process of burning of soot particles, so called DPM (Diesel Particulate Matter) takes plase. Using the right types of diesel fuel and engine oil is also critical to These components can present a variety of issues with different solutions for each, so further research is needed to determine if the forced regen is the answer. Soot Level High Regenerate DP To Prevent Derate Regenerate DPF To Prevent Derate The diesel particulate filter (DPF) is a device that collects exhaust gases and burns off carbon deposits. Read the entire description and do not assume a mention of the word Filter, DPF, SCR,or Aftertreatment means a forced regen is the solution. The DEF system is an after treatment after the exhaust comes out of the DPF. As a side note, newer engines allow for different methods of regeneration, even while parked or in neutral. See how we give back to the essential workers of heavy-duty repair. As the exhaust gasses pass through the filter, it captures somewhere between 85%-100% of diesel particulate matter (DPM). This permits an operator to prevent Reset regeneration may be operated as normal during this cycle. If you notice thicker-than-normal smoke coming out of your car's tailpipe, it could be a sign that the DPF is not working properly and needs to be serviced. (at top) The high exhaust temperature light indicates that passive regeneration is occurring. I give my express consent authorizing TruckersReport and its. The DPF must be rebuilt to eliminate the soot in the engine. A fully integrated payments solution that gives your shop best-in-class credit card & ACH processing, simple fleet check authorization, and a personalized payments portal, all without leaving Fullbay. NarcolepZZZZZZ 2 yr. ago The only light was the DPF Status indicator.don't ever go far enough to get a meaningful active regen. Once the DPF is regenerated, the engine will automatically return to the normal idle speed. be disabled on the unit. 5. The built-up soot is then removed as gaseous carbon dioxide. Eventually, the DPF system needs cleaning when ash levels are too high but regens significantly extend the amount of time before a technician intervention is necessary. Soot Level High. Boost efficiency in your heavy equipment repair shop with fast, flexible software. Repeated instances can threaten driver retention rates, and fleets risk lowering their on-time delivery rates. 118 Satisfied Customers. If you run out of DEF it will derate you to five miles an hour.. Examining data derived from one of the most common engines from JPRO connections, we discovered a significant number of regens performed when there was no suggestion to do so. In other words, build a medical record for trucks. The DPF Soot gauge before last regen was at 3.0 g/l and dropped to 1.53 g/l after regen. The difference could be hundreds of miles to hundreds of thousands of miles, depending on the application, Mustafa notes, with vocational/urban/stop-and-go applications having much shorter intervals than long and heavy. Fuel injectors are responsible for delivering a precise amount of fuel to the engine. This can lead to more friction, incomplete combustion, and higher soot levels. Stay safe, stay healthy & be blessed. machine is parked. Available within the Aftertreatment Diagnostics feature, technicians quickly see which regen zone (0-5) the truck is in and determine the best course of action. It works by trapping the harmful particles as they pass through it and then breaking them down into harmless components during the regeneration process. I can tell you that working on the big trucks when replacing or cleaning a dpf I had to reset the soot level with my laptop. This will only be enabled For drivers engaged primarily in long-haul, with plenty of on-road time at greater than 50 percent of load on the engine, it might go as high as 200,000 to 225,000 miles before any need to shop-test the filter, Mustafa says. The unit will only permit the operator to wait two hours maximum Recently changed differential pressure sensor, and did not take care of issue. In addition to poor regeneration and clogged filters, there are several other factors that can lead to high soot levels in a diesel car. Join the team and help us continue our mission to better life for shops and contribute to safer roads for us all. Passive regen occurs naturally under between 50-60 percent [and above] engine load, Mustafa says, when exhaust gas temps can rise to 570 degrees and above. He wanted to take the best ideas from the electronic medical records world and apply them to heavy-duty repair. Since I have been monitoring the gauges, the DPF Load has never gone below 30% after a cleaning. machines engine. By rejecting non-essential cookies, Reddit may still use certain cookies to ensure the proper functionality of our platform. Passive (self) regeneration occurs naturally Soot Load - DPF soot load in percent reported by engine. Another thing to keep in mind is that the gauge on the dash is a calculation and can sometimes be inaccurate. These filters grab soot from your exhaust before it blows out into the environment. Under these conditions, soot burns off as fast as it is generated! If the DPF soot level is too high, the engine computer program will not allow the system to regenerate. Check out our other blog posts. We turned to Toros Technical Service Team to help explain. Intervals will be shorter, too, if your foot is fairly leaden. This contamination causes unacceptable back pressure. Depending on the severity of the contamination, this process can take several hours, so it's important to make sure you have the right tools and expertise before attempting it. If I shut off the truck prior to regen and the DPF was at 1005, when i started up the truck again, the DPF would read blank until it regened enough to get the % at 100% or below. Regenerations are necessary to prevent particulate matter from quickly accumulating and rendering the DPF ineffective. DPF condition: Filter has exceeded maximum capacity. regeneration system, its right at your fingertips. A reman filter is only as good as how well the person prior to you serviced their vehicle, Mustafa says. if: 1 Year Every month 400 people find a job with the help of TruckersReport. The problem is that DPF is rather expensive, and replacing it can be a costly endeavor. a Recovery regen cycle when requested by the engine.

I have a 2012 w/540,000miles. So, what is Lower-temperature passive regeneration, obviously, notes Mustafa, is way better for the [long-term health of the] system than active regen, also better for mpg given no fuel wasted in a parked process. Check. Cruise off. when the Passive, Assist and Reset regenerations do not adequately reduce the If the soot level is low, can I still perform a forcedDPFregen withOTR Diagnostics or the OTR ResetTool? No active changes in engine operation are involved. Soot Load Percent and Regen By accurately troubleshooting the problem, the solution should become evident. performance and productivity with Toro products. Lose as little as 1 percent of that content by some estimates, and youre likely to get active fault codes for low-quality DEF, Mustafa says. A warning light usually shows up, indicating it is time to literally burn out the accumulated soot. cycles from running automatically. The stop engine light (red) [Ominously] engine damage is probable, Mustafa quotes the Cummins manual, he says.Mustafa was speaking at the Expedite Expo Friday, July 14. You need to monitor your. Manage parts across multiple locations and easily order from vendors. 3. Ultra-low sulfur diesel fuel (less the engine returns to normal operation. (at top) The high exhaust temperature light indicates that passive regeneration is occurring. Mustafas DPF warning-light breakdown **1. Subscribe for updates! The information in this blog post can be used as a general foundation for all makes, models, and engines that have the DPF system. May also be used to If you do a swap with a reman cleaned DPF from another operation, you may be inheriting the issues created by the previous owner (see previous item). For more information, please see our Primarily, Mustafa says, the biggest fault I see as far as DEF fluid is parking the truck for a long period of time and coming back and operating it. DEF is 32.5 percent automotive urea and 67.5 percent water. As another example, diesel trucks that frequently climb hills should have no problem passively regenerating their DPF. Types of Regeneration Knowing when exactly the filter is clogged enough to warrant a bake and/or blow-out (or in the case of Detroits post-2010 units still under warranty, employment of that companys own fluid cleaning method so as not to void the warranty, he notes) is where a somewhat-new maintenance approach is advised. Digital marketing solutions built for heavy-duty truck repair shops. On average, it takes between thirty and sixty minutes to complete a forced regeneration. Turf management news, events, and solutions. Once the exhaust temperature reaches a certain pointwe like to use the example of driving at high speedsthe built-up matter in the DPF turns to ash. Timewise, weve generally found that cleaning a DPF is a quick enough processit can usually be accommodated during an oil change. A DPF system relies on many sensors working correctly. possible. In theory the Cordierite and silicon carbide ceramics should be able to reduce DPM by approximately 70 and 90 percent respectfully. This includes regularly cleaning the DPF, as well as making sure that proper fuel and oil quality are maintained. The High Exhaust Gas Privacy Policy. cancel a Parked regen cycle when the cycle is running. is requested by the engine ECU. Diesel fuel with Drop comments below. DPF regen happens when the trapped particulates heat up enough to combust and turn to ash. if the engine is requesting a Recovery regen. the intake throttle and post fuel injection to further raise the exhaust Work on it with some of your peers, those with similar miles per gallon, driving style and application. when regeneration will no longer clear the system completely.
