DPF Cleaner Works

How Does The RegeFlex® Dpf Cleaner Diesel Work?

The additive operates in two ways:

First, it uses a catalyst to adhere to the soot particles during the combustion in the diesel engine, and then it will be very well dispersed into the soot trapped into the DPF, lowering the temperature at which they can be burnt off.

Secondly, the additive has been formulated with a detergent and deposit control additives package to clean up your high-pressure fuel injection equipment. With the DPF clogging, all the parts and components in the upstream location of the DPF get affected by different types of deposits. Our RegeFlex Dpf Cleaner Diesel will take care of the equipment with cleaning during the vehicle operation.

The driver will experience more power, decreased noise and vibration, reduced fuel consumption, and reduced DPF maintenance after the procedure. These advantages rely on how well the car has driven in the past and how many flaws there are in the system.

The RegeFlex DPF Cleaner's unique blend of chemicals causes the soot to burn at a lower temperature, preventing "runaway" regeneration and failure from overheating during regeneration. Depending on your driving conditions, adding RegeFlex DPF Cleaner to the diesel tank every 5,000 to 10,000 kilometres will guarantee that the filter regeneration occurs under ideal circumstances.

What is a DPF filter?

Diesel Particulate Filters (DPF)–also called soot traps or particulate traps- are more common on the roads today due to ongoing changes in emissions regulations. With BS6 standards in India, Particulate Filters in Diesel vehicle exhausts have been introduced from April 2020 in all on-road Diesel vehicles.

This relatively new way to reduce vehicle pollution has proven to be very successful in providing major reductions to diesel exhaust emissions, especially in reducing black smoke. However, as with any new technology, sometimes there can be some limitations and associated issues. Evidence of these systems failing to regenerate comes to light every day. In Europe and the USA, where this technology has been applied since 2007 in mass production, more and more failures and concerns have been reported from drivers regarding the DPF malfunction light illuminated on the vehicle dashboard indicating a filter blockage, not knowing what it is or what to do about it.

How does the DPF work?

If we talk about the functioning of this filter, then the DPF traps harmful diesel particles that must be adequately cleaned to maintain the vehicle's performance. The DPF cleaning is called "DPF Regeneration," which must be washed regularly using active, passive or forced regeneration. This method effectively renews or regenerates the filter by burning off the accumulated soot at high temperatures (between 520°C and 650°C). Only a residue of ash is left behind.

How many types of DPF systems are there?

Active DPF Regeneration

This strategy is required for all diesel vehicles that are operating under urban city conditions. In that case, the fluctuation of the exhaust temperature cannot support the passive DPF regeneration mode and an active DPF regeneration is required. The target is to generate high temperatures in the DPF to burn the soot during the cleaning process of soot burn-off. All the processes use the engine to generate heat in the exhaust pipe to burn the soot according to the vehicle operation and profile. This active DPF regeneration mode is included in the vehicle from its production step and is fully automatic and transparent for the driver.

The active DPF regeneration is usually supported by a catalyst that can be introduced directly into the diesel fuel - called “fuel borne catalyst” - or a catalyst coating along the channels of the DPF module.

Passive DPF Regeneration

This DPF regeneration strategy is usually dedicated to heavy long haulers trucks and buses for goods and people transportations over long distances and high speed. In that case, the DPF system is located in the hotter part of the exhaust pipe and does not need frequent soot burn-off as the soot is continuously burned during the vehicle operation at high speeds and long distances.

Diesel Particulate Filter (DPF) Blockage Causes

  • The obstruction of the filter in various vehicle types and engine combinations can be attributed to multiple factors. The generation rate of particulates by the engine, the fuel quality, engine oil quality, driving style, and even the placement of the DPF Particulate Filter Cleaner in the exhaust system are all potential contributors to either the filter blockage or the incomplete regeneration process.

  • Usually, the problems arise during intense and long driving conditions in urban areas with successive start/stop driving where the regeneration process might not be complete. A warning light will illuminate, or a message indicating the DPF is 'full' will be displayed on the dashboard. If you continue to drive in the same manner, the soot built up will increase until the warning lights illuminate, and the vehicle will go into limp mode, where driving speed is restricted.

  • This warning stage will now involve a visit to the mechanic to carry out a forced regeneration on the filter. In cases where filters cannot be regenerated will then be replaced. To get  DPF cleaner online you can check our website as we have other products too. 

Causes for the DPF failure:

1- Incorrect Engine Oil: When you use low ash engine oil that does not meet the specifications for your engine, this can contribute to increased soot accumulation.

2- Diesel BioFuel Usage: Using 100% Diesel BioFuels will lead to additional soot buildup in the DPF, potentially affecting its efficiency.

3- City Cycle Driving: The short trips may result in a faster soot accumulation in the DPF. This leads to an incomplete regeneration process that might impact the filter's performance.

4- Inadequate Temperature: The DPF relies on high temperatures, around 600°C, to initiate and complete the regeneration process. 

5- High Kilometer Vehicles: Vehicles with DPF systems may have increasing regeneration difficulty as they age. Like other car parts that may eventually need to be replaced rather than repaired, the DPF may become more burdensome to regenerate due to wear and tear.

6- EGR-Valve, Fuel Injection System, and Turbocharger: these three parts and components of the engine and the vehicle can also be fouled of deposits that can change the emissions from the engine, with, usually, more soot in the exhaust and then into the DPF. This event is not expected and manageable by the engine and the vehicle. The automatic DPF regeneration manager cannot anticipate these modifications and the DPF cannot be properly regenerated

What do I do if my DPF warning lamp is “on”?

“Follow the vehicle manufacturer’s handbook on the procedure to unblock the DPF”. It should be possible to start a complete regeneration and clear the warning lights by driving for 20 to 30 minutes at high speed or high rpm at low gear or at speeds greater than 60 Km/Hr on the highway to heat the exhaust system and facilitate the soot burn-off. 

But when the DPF is fully blocked, this procedure does not support a complete DPF regeneration, and at this point, the customer can add a single 250 ml dose of our RegeFlex® DPF Cleaner BS6 for approximately 30 to 40 litres of diesel fuel. Pouring directly this dose into the fuel tank is simple, safe, and easy to manage for the driver. Then, he has to drive for a certain period to recover his original DPF status. This should clear the warning light within the first few ten to hundred kilometres- depending on how blocked the filter is and its history with the previous DPF regeneration. You can add a second dose with the next tank refilling with 30 to 40 litres of fuel if necessary.


In Summary:-

  • As preventive usage, a 250ml dose has to be added to a 30 - 40 litre fuel tank to keep clean the exhaust DPF and Fuel Injection system, whose effect lasts for about  5,000 km, ie for several DPF regeners.

  • As curative usage "4 -in -1" (DPF code alarm "ON" unusual engine power losses....), (2 x 250ml) doses have to be added to 30 - 40 litres fuel tank to clean up the exhaust DPF system and hot exhaust parts EGR, Turbocharger & clean up the Fuel injection system that has suffered during  DPF troubles ( a min. 100 - 200 km driving is necessary to get complete DPF cleaning.

  • In the case of a large fuel tank  (for instance, with heavy trucks and buses)  the dose has to be adapted to the fuel volume. Soot loading will accumulate until approximately 75% of the filter's capacity if you ignore the light and continue to drive in a comparatively leisurely, stop/start manner. At that point, you should anticipate seeing more dashboard warning lights glow. Driving quickly won't be enough to remove the obstruction at this point. Thus, the vehicle will need to be inspected by a dealer and may require having its DPF manually cleaned or replaced or undergoing forced regeneration.
