Regen a Freightliner
Since EPA's emissions control technology regulations took consequence on the production of diesel-powered engines, truck owners need to know how the process of regeneration works.
This commodity will explore the ways to identify when a regen is necessary, exactly how to regen a Freightliner, and boosted information on after treatment systems.
STEP 1: Which Type of Regeneration Should You Perform?
So at present that you know you need to perform regeneration, which type of regeneration should you perform?
-
i. Parked Regeneration: This is done when regeneration is needed immediately. Regeneration is needed immediately if one of your alarm lamps indicates that as explained above.
-
ii. Passive Regeneration: Occurs all the fourth dimension while the truck is driving at regular speeds. You don't need to practise anything special.
-
3. Active Regeneration: Occurs while the truck is driving at high speeds.
We explicate each procedure of how to regen a freightliner in the next section.
How To Regen A Freightliner With Dissimilar Types of Regeneration: Active, Passive, Parked
Hither nosotros'll discuss the three types of regeneration that can be performed and go into the specific details of how to bear a parked regen of a Freightliner truck with a Detroit diesel fuel engine.
1. Parked Regeneration (Stationary Regeneration)
DPF Switch
Parked or stationary regen is when the truck cleans the DPF while at a standstill.
If y'all've thoroughly read our above information on identifying warning lamps, and so you should know when parked regeneration is needed and when you tin do fine with the active selection.
In other words, if your error codes indicate that regeneration is immediately needed, y'all may desire to park your freightliner and deport parked regeneration. Hither is the process of proper parked regeneration:
Hither's how to regen a Freightliner using the parked/stationary procedure.
- Plow on the engine and slow idle for a few minutes. Make sure that information technology is not in the power-accept-off fashion
- Shift the transmission out of neutral and then back into neutral.
- Shift the parking restriction from OFF to ON
- Press and release the clutch pedal
- Hold the DPF switch to the ON position for five continuous seconds then let go. At this signal, the engine speed will ramp up (RPM increase), and the DPF warning lamp will disappear.
- The parked regen is now in procedure and should take 40 minutes to consummate
- Make certain you practise non push the fundamental in the ignition to the off switch, depress the clutch, release parking brake, or put truck into gear. Whatsoever of these will stop the regeneration.
The regen has ended when the engine returns to slow idle, and the DPF light remains out.
Remember, exhaust temperature increases during regeneration, so it is essential that this procedure is performed outside and away from combustible or combustible materials. Hopefully, y'all are at present educated plenty on how to perform a parked regeneration.
2. Active Regeneration
Active regeneration is the process of burning out the soot by raising the temperature from an outside energy source such as heated diesel or the truck's electricity.
How to practise active regeneration? Well information technology only requires the commuter to bring the vehicle up to highway speeds and no further action is needed. How does it work?
Well, simply, the sensors will detect that regeneration is needed and so fuel will be automatically injected to increment the temperature in your DPF.
This high temperature fuel injected then burns off accumulated soot. In some truck, this procedure may exist washed by an oxidizing catalytic converter that should too be checked and cleaned as needed.
It takes virtually 40-45 minutes of highway speed driving to complete an active regen.
3. Passive Regeneration
Passive regeneration occurs when the truck can maintain right exhaust temperatures then that the DPF can self-regenerate itself continuously.
This type of regeneration is continuously occurring equally the driver goes nigh his business driving the truck as usual.
Passive regeneration is mainly featured in vocational trucks that are intended for off-road utilize such as logging or oilfield vehicles. No activeness is required from the operator for passive regen to occur.
How To Know When Your Freightliner Needs Regeneration?
Start Method: Fault/Fault Code Lamps
The first step is to identify when a regeneration (regen) is needed. The primary way to get updates on the status of your diesel particulate filter and know when a regeneration is needed is to spotter for mistake or warning lamps on your truck's nuance.
Fault Lawmaking Lamps before Freightliner regen
Lets look at these regen error codes:
i. The Malfunction Indicator Lamp/Check Engine
The malfunction indicator lamp is commonly called the check engine light.
This error lamp is based on an the engine-management system and commonly indicates a malfunction somewhere in the engine.
Malfunction Indicator Lamp for regen
For a freightliner, many times the malfunction indicator lamp is a alarm that part of the engine'south emission system is not working correctly.
Detroit Diesel fuel has stated that the truck tin can be driven to the end of the shift and is not a warning indicator that requires immediate attention.
ii. The HEST Lamp
The HEST lamp is for high frazzle system temperature. It ways that the exhaust is at loftier temperature due to extra regen speed which occurs when the truck is traveling at depression rates or is parked.
The HEST Lamp rain
If this lamp flashes information technology ways that parked regen is in progress and that system temperature is not up to par yet.
This warning light is but to circumspection the operator to be careful around the hot exhaust system and to keep flammable materials or vapors at a safe distance.
iii. DPF Status Lamp
DPF lamp is the diesel particulate filter light and if it is stable and so parked regeneration is required presently.
The DPF status light is very important to determine when DPF regeneration is needed for a Freightliner.
Now, in general, DPF warning lights might be solid or flashing. These two states indicate two unlike types of warnings:
DEF Lamp regen
If this light is flashing, then parked regeneration is needed immediately.
The other option hither is to bring the vehicle to highways speed to enable an active regeneration of the filter.
Furthermore, if the DPF lamp illuminates aslope the check engine and stops engine light, and then that means the diesel fuel particulate filter has exceeded system limits, and your only pick is to perform a parked regeneration.
If your truck is reaching its 500,000 miles or 10,000 hours mark, then information technology may fifty-fifty be time to replace the filter system altogether.
Second Method: Use A Scanner
An piece of cake way to bank check if your DPF needs regeneration and bank check the general wellness of your Freightliner is to use apply a scanner/lawmaking reader.
These heavy-duty scanners will tell the health of your DPF, oil and more. The NEXAS LUMNX-NL102P is a keen example and a practiced choice not just for freightliners, merely cars and light-duty vehicles from 1996.You tin can utilize this device to fore regeneration for Detroit, Cummins, Maxxforce and more than.
Third Method: The DPF Status Light Is On Steadily
The steady light is a warning that indicates that your engine may require regeneration. This also indicates that you may have a few or even several hours earlier the engine starts to de-rate.
In such a case, you can perform active or passive regeneration on the truck (these processes are explained beneath).
Basically, all you would have to practice is to bulldoze the at highway speeds (on a highway) uninterrupted. Yous can do so for about 45 minutes or then, but ensure the light goes away.
Forth Method: The DPF Status Lite Is Flashing
Now a flashing light is more than serious as it indicates that your DPF must be regenerated urgently.
This will happen especially if you accept been ignoring the steady DPF status light. This light is telling y'all that parked regeneration is required and should exist performed every bit soon as possible. Parked regeneration is explained below.
Fifth Method: DPF Light Flashing With Check Engine
Parked DPF regeneration must be performed immediately.
Alarm: Remember, if the DPF isn't cleaned for a long menstruation of time, it volition begin to derate. Even more serious, it will shut down at some point in time without whatever additional warning.
Aftertreatment Systems
If your truck has reached the 500,000 miles or 800,000-kilometer interval and a check engine calorie-free illuminates on your truck's dashboard, then information technology may be telling you that manual ash must be removed from the DPF.
This means you or a mechanical technician needs to remove the DPF filter for transmission cleaning.
Often you will need to replace the DPF filter entirely forth with the diesel oxidation catalyst (DOC). This interval may occur sooner depending on your truck'southward engine model/make/year.
Moreover, be informed of DPF filter cleaning methods and avoid the "bake & blow" procedure that blow compressed air into the DPF substrate to remove loose ash.
Sometimes thermal baking is used to burn off hydrocarbons clogging the filter. However, these methods are not correct cleaning methods and can damage an after-treatment system.
New Diesel Particulate Filter For Detroit Filter
In some cases, you may simply want to change your DPF. At present if your Freightliner has a Detroit diesel engine, it'southward pretty easy to go a replacement DPF. In fact, yous tin can go one on Amazon!
The DD15 A6804910594 is a DPF for the 2007 2008 2009 Detroit Diesel fuel DD15.
Decision
Smog can be caused by deleting your dpf
The Environmental Protection Agency put engineers at Detroit Diesel in a position of little choice regarding meeting its ready-out regulations.
However, while the early on applied science for controlling emissions may not have been the about reliable, newer models accept improved significantly regarding fuel efficiency and maintenance.
Look at the image beneath and run across how countries such as Mainland china who have less strict pollution laws appear.
