Pros And Cons Of DPF System
Diesel particular filters or DPFs have become the solution of choice for many manufacturers for dealing with soot as well as Ash when burning diesel. In essence, they’re an exhaust filter that collects soot and stores it to be processed in a DPF burn.
The focus is on performance and we are all aware that any restriction can affect the efficiency that an engine can provide. So , what do we do to fix the DPF? What exactly is it? And how to take care of it?
The DPF can be removed from the exhaust and software. This is a simple solution to the problems caused by an DPF. I’m not going explain the legal aspects of removing an emission-related device. I’m just saying this is the most straightforward solution.
One advantage of the DPF is that it reduces the amount of soot released into the atmosphere. It is, according to some, a positive benefit for the environment. It’s a vague statement at best. It is crucial for a DPF to regenerate or burn off soot frequently. How to do this is to make the DPF sufficiently hot to burn off soot so it can be able to pass through filter. The way to do this is the ECU injects fuel in addition to generate temperature in the filter for it to melt away the soot. The process is obviously more fuel (not eco-friendly) The result is that a significant amount of this extra fuel enters your engine’s sump, which diluents the engine oil , which could mean additional oil and filter changes.
Similar to catalytic converters were first introduced and lead was taken out of fuel since it could harm the converter. Cars equipped with DPFs require special oils that are not high in sulfate-ash, phosphorus and sulphur (low saps). A wrong oil will cause blockage of the DPF and hinder its regeneration making it essential to replace the DPF. One downside of DPF is the cost to replace.
Some say that the requirement for oil in the DPF causes internal wear rate of the engine greater than when a normal oil was employed. We will debate that another day.
One of the biggest issues we face in DPFs is the case of a boost leak. A boost leak can cause more soot to build up in the exhaust system and block the DPF pretty quickly. After the leak has been repaired, then a DPF cleaning is almost always going to be required. You can conduct a DPF clean with the DPF still in the car. After the DPF clean has been performed there is the possibility of a regen. When it is necessary to perform a forced regen it is required after the regen. Why, remember before how it is necessary to inject additional fuel to get the DPF sufficiently hot to allow it to be able to regulate, this extra fuel will alter the oil in the engine.
compelled regen
What is a compelled regen? A forced regen is using a scan tool in order to start a fire while your vehicle remains stationary. The majority of times, a regen that is forced will employ a higher temperature, and the regen tool will monitor the pressures of the dpf filter when it is in use. Certain tools are required to conduct a forced re-generation therefore your typical mechanic might not be able this. However, you do not have to use the dealer. We recommend a variety of fully equipped workshops. They have the technology to carry out the forced regen.
extreme instances
In the most extreme instances, forced regens won’t be possible because of the volume of soot loading. The next step in the process is to perform an on car clean. Our car cleaning tool involves two steps. A cleaner is injected into the DPF and works to remove the soot in a specified period of time. The cleaner is then removed out of the system, leaving the DPF ready for a forced regen. The car-specific cleaning equipment is much less common for an establishment to have. We are also able to assist on car DPF cleaning.
This is just a brief overview of the DPF and a few of the pros and cons related to its application.
