    Posted by Karl Sep 13, dpf-diesel-particulate-filter 4 Not a day goes past without some form of DPF tweet, email or message from fellow motorists suffering at the hands of a clogged filter.

    Normally its the same old thing but yesterday I got an email that broke the trend. I found a button that looks just like this — what does it do?

    What does it do? The procedure for using the button may differ from vehicle to vehicle but the steps below seem to be the norm. Before Pressing the button Firstly make sure you are in a well ventilated area, preferably outside. Make sure that your vehicle is not parked over dry grass or any other matter that may burn or catch fire. To kick off a manual DPF regeneration you should Put the vehicle in neutral Put on the hand brake Leave the pedals alone! Press and hold the DPF button for 2 seconds or longer When the conditions above are met the engine revs should rise as the process begins.

    It can take anywhere from 5 minutes to over an hour depending on how blocked the filter is. During this time you should keep an eye on the engine temperature and make sure it does not overheat. The fans should cut in to prevent this however we suggest you stay with the vehicle to prevent damage caused by overheating. Should I change the engine oil after the DPF clean? Much like a dealer regen we suggest that the engine oil should should be changed after a DPF regeneration.

    This is due to the extreme temperatures the engine is subjected to during the process. Most people are unaware the process is happening unless the DPF warning light comes on.

    Vehicles such as large trucks and 4x4s often spend a large proportion of this life at much lower speeds than is required for an automatic regeneration — thus have a button. If you have a magic DPF button or any experiences with it then please do get in touch in the comments below.

    Can you clean a DPF?

    November 11, Img source: thenewswheel. Most vehicles that rely on diesel are generally heavy-duty commercial vehicles but can include passenger vehicle brands such as Volkswagen. It is evident that a small fraction of prevention is worth its multiple of cure and this holds very true for diesel engine powered vehicles. In this article we explore the topic of DPF delete and mention its benefits if any and drawbacks.

    What is Diesel? Diesel is a liquid which is made from fractionally distilling petroleum fuel oil. It is the process of distillation that makes diesel a distinct fuel type.

    There are sub-types of diesel fuel such as biodiesel, BTL, GTL but petro-diesel which is standardized as ultra low sulfur diesel is the most common version. Ultra low sulfur diesel has a reduced sulfur content which was initiated as part of an emissions control campaign to make it both compatible with new emerging technologies and to lower the harmful toxins released from vehicle exhausts. Even though the sulfur content in LSD is relatively low, it became a mandate of the United States government in for highway-vehicles to strictly adhere to using only USLD.

    Locomotive and marine vehicles followed in What is a Diesel Particulate Filter? Img source: pinterest. It works by trapping soot and harmful contaminants. Eventually, the soot in the DPF filter builds up and it requires cleaning.

    As a result, the DPF filter undergoes regeneration and the soot is burned-off via high temperature heat. Regeneration is an important part of maintaining the DPF system on your vehicle because without it the DPF filter can become clogged enough that even cleaning it manually will not save its usefulness. The filter is very similar to a catalytic converter except for the fact that it is not a flow-through device.

    Health Hazards of DPF Delete There are many health hazards associated with DPF delete and most of them have to do with the substrates that the exhaust system of a diesel engine vehicle releases into the atmosphere.

    For people with respiratory problems such as asthma, bronchitis, and lung disease, it can aggravate the illness. The Environmental Protection Agency EPA has identified three key pollutants found in diesel fuel burning vehicles which are nitrogen oxides, hydrocarbons, and carbon monoxide.

    EPA Fines and Regulations The Environmental Protection Agency is the government body responsible for setting out strict emissions standards for diesel engine vehicles. For several decades now, the EPA has been setting out regulations specific to auto vehicles in order to combat and control the pollution they emit into the atmosphere.

    New diesel engines had to emit fewer particulates and lower levels of nitrogen oxides in order to pass these stringent requirements. This expanded the emissions regulations established by the EPA in Therefore, companies that are affluent and have a broader impact to harm the general health of the environment and public are dealt with harsher penalties than individuals that take their vehicles into a local mechanic shop to get a straight pipe retrofitted.

    The fines of for DPF deleting can range from a couple thousand dollars for individuals to tens of thousands for small-medium companies participating in supply and retrofitting DPF delete systems.

    One of the best ways to prevent DPF delete is to ensure that you regularly regenerate the diesel particulate filter on your vehicle. The process is very simple and all you need to know if how to activate the regeneration process which is usually a combination of pressing a few buttons and pressing the clutch depending on the type of vehicle you have. Furthermore, we highly recommend you pick up two key pieces of equipment in your DPF maintenance journey.

    They are a diesel exhaust fluid refractometer and a DPF cleaner. Diesel exhaust fluid enters the engine system to work to control nitrogen oxide pollutants and ensuring that there is an accurate urea concentration will prevent breakdowns and hefty repair bills. A DEF refractometer works to let you know if your diesel exhaust fluid is good or needs replacement.

    Secondly, a DPF cleaner involves catalyst reactions and will help deteriorate the trapped soot inside the filter. DPF cleaners can also activate the regeneration process inside the filter. Sustainability Energy supplies a DEF refractometer as part of its e-commerce platform to increasing sustainability. You can collect yours today at Amazon. The DEF refractometer arrives with a screwdriver to adjust the prism, an instructions manual, a carrying case, solution dropper, and the refractometer itself.

    It thoroughly cleans the filter and helps initiate the regeneration process. This system met the emissions standards through air management, highly controlled combustion, improved electronics and an after-treatment system. These changes led to significant problems that affect the people who rely on this technology in the field.

    The new features added to the C13 and C15 engines from Caterpillar, following the introduction of EPA guidelines, have led to numerous problems. Increased repair time, wasted miles and unnecessary costs can all result. While the problems caused by the new engine configuration show up in a variety of ways, they share a similar cause. When the soot builds up, the Electronic Control Module starts the regeneration system, which burns up the soot and circulates the air back through the system.

    In some cases, this regeneration cycle is not triggered properly. This leads to computer errors causing the vehicle to shut down, clogged Aftertreatment Regeneration Device ARD heads, low back pressure leading to lack of proper filtration and fluid dilution, and other potential problems.

    When the Cat Regeneration System does not activate, the computer kills the engine. The most common sign that the system is faulty is that the ARD head gets clogged. When that happens, the truck has to go into the shop, the ARD head must be removed and cleaned out or replaced, and the computer must be reset.

    Depending on whether you need a new part, and whether the nearest authorized service location has the part, you can lose significant time to this repair. To separate itself from competitors in the race to maintain power and fuel economy while meeting stringent new emissions standards, Caterpillar designed an entirely new system that is used on its C13 and C15 engines.

    While other companies focused on cooling and re-circulating the exhaust back through the engine, Caterpillar attempted to meet emissions standards by changing the initial combustion profile and by dealing with particulates in a new way. This involves injecting a controlled amount of fuel into the system and burning off the soot. All of this is meant to happen automatically in order to save maintenance time.

    While undoubtedly meeting EPA standards, the engines with this configuration have experienced numerous problems and cost the owners and operators of these trucks significant time and expense. In many cases, the ECM would fail to detect soot buildup and the truck would simply shut down.

    However the problems arise, Caterpillar should be held accountable for the defective design and the economic harm suffered by those who purchased vehicles with the and newer emissions packages. In an effort to meet emissions regulations, Caterpillar added new features to its model trucks.

    An electronic control module is supposed to detect soot buildup and add a precise amount of fuel to oxidize the soot. Early engines with this package have experienced significant problems, leading to excessive down time, missed deadlines, tow costs, repair costs and a host of other negative consequences for their owners.

    As is the case with this case study, it is evident that manufacturers including Ford Powerstroke and Cummins ISX had a difficult time in the early days of DPF filters and regeneration. However, you are not likely to see these issues in modern vehicle models because both manufacturers and vehicle owners have accepted the fact that the diesel particulate filter is part of doing business with fossil-fueled powered technology. It may be the case that the future will yield more energy efficient vehicles that are powered through renewable sources such as electricity non-fossil fuel based or that existing systems will improve altogether.

    Conclusion Img source: pexels. It mentions preliminary information to understand diesel fuel, filter systems, EPA fines for deleting emissions technology, solutions for maintaining the DPF, and a case study involving a manufacturer.

    If you found this article helpful and a deterrent in deleting the DPF, we feel you and us have done the task of preserving the environment and public human health.

    The Dangers of DPF Delete – 2020 Review

    Normally with the first tank of treated fuel. What can prevent normal regeneration from taking place? The single biggest cause of incomplete DPF regeneration is the duty cycle of the vehicle.

    Engines need to achieve extended periods of high temperature, high RPM activity in order to complete a DPF regeneration. DPF Remedy keeps this from happening.

    Diagnosis sequence The majority of vehicle manufacturers have the same warning light sequence but you should always check the vehicle handbook to be safe.

    Diesel Particulate Filter (DPF) Regen and Repair

    This is not covered under warranty. Useful checks and advice 1. Check pressure sensors as there could be a build up of water; 2. Examine pressure pipes for damage. They must be clean or they could freeze in extreme temperatures due to water build up; 3. Check that the EGR system is working correctly; 4. Check that the vehicle has the correct specification engine oil; 5.

    The engine is set to run in a certain specific way and can inject up to eight times more fuel per stroke to produce a high amount of NO2, which will help oxidize the particulates, increasing the temperature as the exhaust gases pass through the catalytic converter; 7. It is advisable to check the oil for diesel contamination as a result of constant DPF regeneration.
