How to Regen a Kenworth T680

The Kenworth T680 is a popular choice for long-haul trucking. Its powerful engine and aerodynamic design make it a great option for drivers who need to get the job done quickly and efficiently. However, like all diesel engines, the T680’s emissions system requires regular maintenance to keep it running smoothly. One of the most important maintenance tasks for a T680 is to perform a regeneration, or “re-burn.”

A regeneration is a process that burns off the soot and other harmful emissions that build up in the diesel particulate filter (DPF). If the DPF is not regenerated regularly, it can become clogged and eventually fail. This can lead to expensive repairs and downtime.

Performing a regeneration on a T680 is a relatively simple process, but it is important to follow the manufacturer’s instructions carefully. In this article, we will walk you through the steps of regenerating a Kenworth T680.

We’ll also provide some tips on how to keep your DPF clean and functioning properly. So if you’re a T680 owner, read on to learn how to regen your truck like a pro!

What is a Regen and Why Do I Need to Do It?

A regen, short for regeneration, is a process that cleans the particulate matter (PM) filter on a diesel engine. The PM filter traps soot and other pollutants from the exhaust, and over time, it can become clogged. A regen burns off the accumulated soot, keeping the filter clean and working properly.

There are two types of regens: passive and active. A passive regen occurs when the engine is under heavy load, such as when climbing a hill or towing a heavy load. The increased exhaust temperature burns off the soot. An active regen is initiated by the truck’s computer when the PM filter reaches a certain level of saturation. The computer injects extra fuel into the exhaust, which causes the temperature to rise and the soot to burn off.

Regens are important because they keep the PM filter clean and working properly. A clogged PM filter can restrict airflow, which can lead to decreased fuel economy and performance. It can also cause the engine to run rough and emit more pollutants.

How to Perform a Regen on a Kenworth T680

To perform a regen on a Kenworth T680, you will need:

• A Kenworth T680 truck
• A DPF Regeneration Tool (available from your Kenworth dealer)
• A safe place to perform the regen, such as a large parking lot or truck stop

Step 1: Connect the DPF Regeneration Tool to the truck.

The DPF Regeneration Tool plugs into the truck’s diagnostic port. Once connected, the tool will automatically start the regen process.

Step 2: Follow the instructions on the DPF Regeneration Tool.

The DPF Regeneration Tool will display instructions on how to perform the regen. These instructions may vary depending on the model of your truck.

Step 3: Allow the regen to complete.

The regen process may take several minutes to complete. Once the regen is complete, the DPF Regeneration Tool will notify you.

Step 4: Disconnect the DPF Regeneration Tool.

Once the regen is complete, you can disconnect the DPF Regeneration Tool from the truck.

Important Safety Information

• Always perform a regen in a safe place, such as a large parking lot or truck stop.
• Do not perform a regen while the truck is in motion.
• Do not perform a regen if the truck is low on fuel.
• Do not perform a regen if the truck is overheating.
• Do not perform a regen if the truck is smoking.

If you have any questions about performing a regen on your Kenworth T680, please consult your Kenworth dealer.

How To Regen A Kenworth T680?

Regeneration, also known as a “DPF burn,” is a process that removes harmful soot from a diesel particulate filter (DPF). The DPF traps soot as it passes through the exhaust system, and regeneration burns off the soot so that it can be released through the exhaust.

Regeneration is an important part of maintaining a Kenworth T680, as it helps to keep the DPF clean and functioning properly. If the DPF becomes too clogged with soot, it can cause the engine to run poorly and emit excessive smoke.

There are two types of regeneration: passive and active. Passive regeneration occurs naturally as the engine runs, and it is not something that the driver needs to do anything to initiate. Active regeneration, on the other hand, is a more intensive process that is initiated by the driver.

Active regeneration is typically performed when the DPF is nearing its capacity for storing soot. The driver will see a message on the instrument cluster indicating that a regeneration is required. To initiate the regeneration, the driver will need to press the “regen” button on the dash.

The regeneration process will take several minutes, and during this time the engine will run at a higher RPM and the exhaust will be hotter than normal. It is important not to interrupt the regeneration process, as this could damage the DPF.

Once the regeneration is complete, the message on the instrument cluster will disappear. The DPF is now clean and ready to continue filtering the exhaust.

What to Do If Your Regen Fails

If the DPF regeneration fails, it can cause the engine to run poorly and emit excessive smoke. There are a few things that you can do to try to fix the problem:

• Check the engine oil level. If the oil level is low, it can cause the engine to run hot, which can lead to a failed regeneration.
• Check the fuel filter. A clogged fuel filter can restrict the flow of fuel to the engine, which can also lead to a failed regeneration.
• Check the air filter. A dirty air filter can restrict the flow of air to the engine, which can also lead to a failed regeneration.
• Have the DPF inspected. If the DPF is clogged with soot, it will not be able to regenerate properly. A qualified technician can clean or replace the DPF as needed.

If you are unable to fix the problem yourself, you should take your truck to a qualified diesel mechanic.

Tips for Extending the Life of Your DPF

There are a few things you can do to help extend the life of your DPF:

• Drive your truck regularly. The DPF needs to be heated up in order to regenerate properly, so it is important to drive your truck regularly for at least 20 minutes at a time.
• Avoid short trips. Short trips do not allow the DPF to heat up enough to regenerate properly, so they can shorten the life of the DPF.
• Avoid idling your truck. Idling your truck wastes fuel and can also shorten the life of the DPF.
• Use the right grade of fuel. Using the wrong grade of fuel can damage the DPF.
• Have your truck serviced regularly. A qualified diesel mechanic can inspect your DPF and make sure that it is functioning properly.

By following these tips, you can help extend the life of your DPF and keep your Kenworth T680 running smoothly.
