Pros And Cons Of DPF System
Diesel particular filters or DPFs are now the method of choice for numerous manufacturers to deal with soot and ash after burning diesel. They are basically an exhaust filter that absorbs soot and store it to be processed in a DPF burn.
We are all about performance and we’re aware that any restriction can affect the efficiency the engine. What can we do about the DPF? What exactly is it, and how do we take care of it?
The DPF can be removed out of the exhaust and software. This is the simplest solution to the problems due to having the DPF. It is not my intention to go into all the legal ramifications of taking out an emission-related device. I’m just saying this is the best solution.
One good thing for the dpf is reducing soot getting into the air. Many would consider it a benefit to the environment. It’s a vague assertion at best. It is crucial to renew a DPF or burn off soot frequently. The method to achieve this is by making the DPF sufficiently hot to burn off the soot , so that it will pass through the filter. The way to do this is that the ECU injects additional fuel to generate additional heating in the filter that causes it to burn off. Doing this obviously uses more fuel (not environmentally friendly), and an amount of this additional fuel also is absorbed into your engine’s sump, which diluents the engine oil which can result in additional oil and filter changes.
Similar to catalytic converters were first introduced and lead was taken out of fuel since it could cause a problem for the converter. Vehicles that have DPFs require specific oils that are low in sulfate , as well as phosphorus and sulfur (low saps). Incorrect oil blocks the DPF and prevent its regeneration. This makes it necessary to replace the DPF. One downside of DPF is that it is expensive to replace it.
Some believe that the oil requirement of the DPF causes internal engine wear rates more than if an ordinary oil was employed. We will debate that another day.
The main issue we have in DPFs is when a boost leak occurs. A boost leak could cause additional soot within the exhaust system, and will block the DPF quite quickly. After the leak has been resolved, the DPF clean is likely to be required. It is possible to do a DPF cleaning while having the DPF still installed on the car. Once the DPF clean is complete, there is the possibility of a regen. Whenever it is necessary for a regen to be forced an oil change to the engine is needed following the regen. How do you know? When you inject fuel in order to make the DPF sufficiently hot to allow it to be able to regulate and this additional fuel will alter the oil in the engine.
forced regen
So what is a forced regen? Forcing a regen is a making use of a scanner tool to initiate a burning while you are stationary. In most cases, a forced burn will employ a higher temperature, and the tool used to regulate the pressures of the DPF when it is in use. Certain tools are required to perform a forced regen therefore your typical mechanic might not be able this. But there is no requirement to work with a dealer. We are a fan of a few well-equipped workshops , and they do have tools to execute force regen.
In extreme cases, an forced regen may not be possible due to the high amount of soot loaded. The next step in the process is to perform an on-car clean. The on-car cleaning tool is a two-step procedure. A cleaner is injected into the DPF and processes the soot for a certain duration. The cleaner then is removed out of the system leaving the DPF in good condition for a regen. The cleaning equipment in the car is not as common for a workshop to have. We also can assist on-car DPF cleaning.
This is just a brief overview of the DPF and some of the advantages and disadvantages regarding its application.
