The following InfoCenter icons are designed to provide quick, 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. 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. It starts solid, asking you please, Mustafa adds, then begins to blink to signal greater urgency, and your engine begins to derate, or reduce power output.**3. Fullbays leading technology integrates seamlessly with other industry tools. A DPF is basically a filter that captures soot particles from the exhaust gases of diesel engines. In other words, build a medical record for trucks. 2. Engines MCM will try its best to get rid of harmful soot by regenerating DPM by its own algorithm, but if it does not succeed one of four (4) scenarios will take place with DPF along with corresponding indicator lamp on a dash being lit: 1. Reset regeneration uses a combination of start a Parked regeneration within the InfoCenters Service menu (it typically The High Exhaust Gas You need to monitor a few parameters to assess whether or not it is necessary to run a forced DPF regen. Parked Regen Used to start a Parked 4. Tell-tale symptoms of a successful (or unsuccessful) forced DPF regeneration. Provide consistent, dependable repairs and maintenance that emergency vehicles can rely on. If the engine is not running correctly, or if there are any mechanical issues like worn parts or poor compression, this can lead to more soot being produced as well. Are these trucks not capable of regening while driving? The machine Youll need to clean very, very carefully so as not to damage the filter, and removing particulate matter must be handled with the proper equipment and care so technicians are not exposed to its extremely fine contaminants. the last regen was more than 50 hours ago. A warning light usually shows up, indicating it is time to literally burn out the accumulated soot. Making sure the truck is on a regular preventive maintenance program will help ensure the long life of the DPF, as will regularly replacing air filters and fuel filters. however, no action is required by the operator, and the machine may be operated 2 Years How often should DPF Regenerations take place? Paying attention to dash symbols and trying to drive long distances at a time will allow the DPF system to do its job properly and increase longevity of its potential. While expensive for truck owners, the removal of diesel particulate matter before it blows into our breathing air certainly has its benefits, and using the correct type of oil for the engine will also help prevent unnecessary wear and the problems that can come with it. A DPF system relies on many sensors working correctly. If any of these sensors has an issue that triggers a fault code, a regen will not fix the problem without first isolating and repairing the malfunctioning sensor. The last regen started at 509 miles. A forum community dedicated to Chevrolet and GMC diesel truck owners and enthusiasts. You Have The Right to Repair This TruckOr Do You?

The engine can derate when a needed regen does not occur, potentially causing downtime by leaving the vehicle in a state that is either undriveable or in limp mode where it can only operate at slow speeds. Youll also want to get to work on it sooner rather than later, as continuing to operate the vehicle at this stage can ruin the DPF and cause other damage. Considering the 1114 unnecessary regens, we discovered on a single engine model when only one active fault was present, between 1114 and 1671 gallons of fuel were wasted on unnecessary regens. In these cases, an active regeneration occurs. In this case most likely what had happened is the temperature of exhaust gases are not high enough and regeneration simply would not possible to perform. Level 2: (Amber light with DPF sign is flashing) Filter regeneration Necessary. Soot Level Low, Why Force a DPF Regen? (3-Minute Read) Nich1019.

Regeneration, or regen, of the DPF filter, is the process that burns the soot accumulation that is inside the DPF filter. Don't Worry, It's Normal: Tier 4 Regeneration Explained is activated by the engine ECU. 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. Daniel Mustafa, Assistant Manager of Technical Development for TravelCenters of America, says he still sees otherwise upstanding, wonderful people doing the kinds of things with their trucks that can turn a less-than-$1,000 major nuisance repair into a soul-crushing $11,000 one. Timewise, weve generally found that cleaning a DPF is a quick enough processit can usually be accommodated during an oil change. Choosing a selection results in a full page refresh. As a side note, newer engines allow for different methods of regeneration, even while parked or in neutral. A better life for shops leads to safer roads for us all. 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). * An UNNECESSARY REGEN indicates the vehicle was in a regen zone (0/1) where a forced regen is not recommended, ** A NECESSARY REGEN indicates the vehicle was in a regen zone (2-5) where a forced regen is recommended. Active regeneration happens when changes in engine operation are required to get the Engine Control Module (ECM) to burn out and/or some catalyst is introduced.

Repairing required not just baking/blowing the ash out of the particulate filter but replacing the diesel oxidation catalyst (DOC), just upstream of the particulate filter in the exhaust system, the DPF itself and a turbo, given excessive exhaust backpressure had damaged it. cancel a Parked regen cycle when the cycle is running. COTC PACCAR MX-13 & Kenworth Truck Regeneration ('ReGen') DPF condition: Filter has exceeded maximum capacity. Important The DPF Load gauge is 0 to 100 %. We equip you with the power to perform advanced diagnostics easier and faster than ever before while over the road. 6-11 Months The main active components of all DPF filters are ceramic cell matter, based on Cordierite and silicon carbide ceramics. 1.Yes idling is the worst thing for DEF/DPF systems, evidently the exhaust gas temps and pressures are not high enough during idling to burn off the soot. As another example, diesel trucks that frequently climb hills should have no problem passively regenerating their DPF. Some cars may also have indicators that will let you know if there are any issues with the DPF. A DPF is basically a filter that captures soot particles from the exhaust gases of diesel engines.
