What Is Regen?

Wondering what is Regen? Regen is a process that occurs when the engine is running and the vehicle is stationary. The purpose of regen is to clean the exhaust system by burning off any deposits that have built up on the catalytic converter or diesel particulate filter.

How Does Regen Work?

The engine management system monitors the level of exhaust deposits and when they reach a certain level, the system initiates a regen. The process starts by slightly increasing the engine temperature to help with the burning off of the deposits. This is done by injecting small amounts of fuel into the exhaust system. The fuel ignites and burns off the deposits. The process can take up to an hour to complete and during this time, the vehicle may produce more smoke than usual from the exhaust.

Why Is Regen Important?

Regen is important because it helps to keep the exhaust system clean and operating efficiently. A build-up of deposits can eventually lead to a blockage in the exhaust, which can reduce engine power and efficiency. It can also cause the vehicle to fail an emissions test.

How Often Does Regen Need to be Done?

The frequency of regen will depend on how the vehicle is driven. If the vehicle is mainly driven short distances, then the build-up of deposits will happen more quickly and regen will need to be done more often. However, if the vehicle is driven mainly on long journeys, then the build-up of deposits will happen more slowly and regen can be done less often.

How Do I Know If My Vehicle Needs a Regen?

Most modern vehicles are equipped with an engine management system that will monitor the level of exhaust deposits and initiate a regen when necessary. However, some older vehicles may not have this system and a visual inspection of the exhaust may be required to check for a build-up of deposits.

What Causes Exhaust Deposits?

Exhaust deposits are caused by a build-up of soot and other particles in the engine’s exhaust system. These particles can come from a variety of sources, including engine oil, fuel additives, and even the air filter.

What Are the Symptoms of a Clogged Exhaust System?

If the exhaust system is clogged, it can cause a number of problems, including:

  • decreased fuel economy
  • increased engine noise
  • and reduced power

In severe cases, it can even lead to engine damage.

How Does Regen Fix the Problem?

Regeneration is the process of burning off these deposits, restoring the efficiency of the catalytic converter or diesel particulate filter. This is typically done by injecting a small amount of fuel into the exhaust stream, which ignites and burns off the deposits.

What Are the Benefits of Regen?

1) Increased Fuel Economy

By keeping the exhaust system clean, regen can help improve fuel economy by up to 5%.

2) Reduced Emissions

A clean exhaust system means fewer harmful emissions being released into the environment.

3) Improved Engine Performance

With fewer deposits clogging up the engine, it can run more smoothly and efficiently.

4) Extended Engine Life

By preventing engine damage from a clogged exhaust system, regen can help to extend the life of your engine.

5) Fewer Maintenance Costs

Fewer exhaust deposits means less frequent trips to the mechanic for cleaning or repairs.

How to Avoid the Need for Regen

1) Use High-Quality Fuel

Using high-quality fuel can help to reduce the build-up of deposits in the engine.

2) Use a Fuel Additive

Adding a fuel additive to your tank can also help to reduce the build-up of deposits.

3) Drive More Efficiently

Driving more efficiently can help to reduce the amount of deposits that are produced.

4) Get Your Vehicle Serviced Regularly

Getting your vehicle serviced regularly can help to keep it running smoothly and prevent a build-up of deposits.

5) Use the Right Oil

Using the wrong oil can cause an increase in deposits. Make sure you use the correct oil for your vehicle.

How to Prepare for a Regen

1) Check Your Fuel Level

Make sure you have enough fuel in your tank before starting the regeneration process.

2) Find a Safe Location

Find a safe location to park your vehicle before starting the regeneration process.

3) Turn Off the A/C

Turn off the air conditioning before starting the regeneration process.

4) Turn on the Engine

Turn on the engine and let it idle for a few minutes before starting the regeneration process.

5) Follow the Instructions

Follow the instructions that came with your regeneration kit to ensure that the process is done correctly.

6) Monitor the Progress

Monitor the progress of the regeneration process and make sure that it is completed properly.

7) Let the Engine Cool Down

After the regeneration process is complete, let the engine cool down before driving.

8) Check the Oil Level

After the regeneration process is complete, check the oil level and add more if necessary.

9) Check the Tire Pressure

After the regeneration process is complete, check the tire pressure and inflate the tires if necessary.

10) Reset the Engine Hours

After the regeneration process is complete, reset the engine hours so that you can keep track of when the next one is due.

The main drawback of regeneration is that it can cause increased engine noise and vibration. Additionally, it can take a significant amount of time to complete, which can be a problem for busy drivers.

Overall, regeneration is a necessary process that helps keep the engine running smoothly and efficiently. While it can cause some short-term inconvenience, the long-term benefits far outweigh any negatives.
