How to clean the diesel engine filter. Removal and cleaning of diesel engine filter: photo and

According to the particulate filter, in most cases it is amenable to regeneration, which can make OF. Dillers Connecting their computers and in a certain way "rolling" it, and so at normal work, he must self-clean, if it did not happen, the diesel has problems trying more than this filter because we have a diesel engine, and not a catalyst ...
Therefore, this is not a standard Diesel problem. This is a consequence ...
Some really collectively ... washed with aviation kerosene and on the road ...

Well, as a library ...

The particle filter is designed to reduce the emission of the particulate parts into the atmosphere with the exhaust gases.
IN exhaust system diesel engine The particle filter is usually combined with a catalytic neutralizer of oxidative type. Such a filter is the name of a diesel fiber with a catalytic coating. A catalytic oil filter is installed on the exhaust manifold in the immediate vicinity of the engine.
The main constructive element squeeze filter Is the so-called. The matrix, which is made of ceramics (silicon carbide). The ceramic matrix has a cellular structure consisting of small cross section channels alternately closed with one and the other side. The walls of the channels have a porous structure and perform the role of filter. A thin layer of the catalyst - titanium is applied to the surface of the walls. The matrix is \u200b\u200bplaced in a metal case.
The principle of operation of the particulate filter:
When passing out the exhaust gases through the scene filter, the soot particles are delayed on the surface of the matrix walls. The catalyst applied on the walls of the matrix contributes to the oxidation of unburned hydrocarbons and carbon monoxide.
Cleaning the filter from the accumulated soot occurs by regeneration. There are active and passive regeneration of the particulate filter.
With passive regeneration, there is continuous soot oxidation due to the action of the catalyst and high temperatures Exhaust gases (350-500 ° C). The chain of chemical transformations with passive regeneration has the following form: nitrogen oxides react with oxygen in the presence of a catalyst to form nitrogen dioxide; nitrogen dioxide reacts with soot particles (carbon) to form nitrogen and carbon monoxide oxide; Nitrogen oxide and carbon black gas react with oxygen to form nitrogen dioxide and carbon dioxide.
With certain modes of engine operation (small load, etc.) there is no high temperature of the exhaust gases and passive regeneration cannot occur. In this case, active (forced) regeneration of the particulate filter is carried out.
Active regeneration occurs at a temperature of 600-650 ° C, which is created using the engine control system. At this temperature, the soot particles react with oxygen with the formation of carbon dioxide.
The active regeneration control of the particulate filter is carried out using the following sensors: air flow meter; exhaust gas temperature sensor before the scent; Exhaust gas temperature sensor after a smbed filter; Pressure drop sensor in the Saint Filter.
Based on electrical sensor signals the electronic unit The control produces an additional fuel injection into the combustion chamber, and also reduces the air supply to the engine and stops the recycling of the exhaust gases. At the same time, the temperature of the exhaust gases rises to the required value.
What does Piece, he controls the sensors in such a way that to enter the engine to the active mode (maximum allowable) mode of regeneration.
that's all...

Saya - Corrosion Side Product fuel mixesAnd its volume in the exhaust directly depends on the proportions of fuel and air. On the sieve, the soot gets up a scene filter. It delays up to 95% harmful emissions - Does not let them out and burns. Excessive clogging of this part leads to a decrease in car power.

Why is the scene filter clog?

When driving, the filter is gradually clogged. This process monitors special sensors. Automatic regeneration can destroy the accumulated soot by burning it, but this happens only when driving over long distances. As a result of the additional supply of the fuel mixture, the temperature in the filter reaches 700 degrees, which contributes to the complete burning of the accumulated soot.

If you ride only within the city trait, partial burning of pollution will occur, which does not solve the problem. Filter clogging continues.

Over time, it becomes critical - it is necessary to change an element that can cost 800 euros. By the way, the use of poor-quality gasoline "contributes to" to wear. Riding with a clogged filter leads to the fact that regeneration is activated systematically, but the full burning of the soot due to its large quantity does not occur. Moreover, the system is clogged even rapidly, since it is too frequent to launch a regenerative process that does not completely burn out fuel. The remaining substances fall into the exhaust.

A part of the unburned mixture can also get into the oil, worsened its quality. Excessive pressure raises the oil level - in the end it will fall into the intercooler. Too high pressure is able to "kill" the motor. That is why the filtering system should be flushed from time to time using a special cleaner.

Signs of clogging of the particulate filter

Symptoms include critical clogging of the filtering system:

• increase fuel consumption;
• high level oils in the system;
• the thrust decreases (as indicated by the instruments);
• on the idling Motor is unstable;
• with the onboard engine, suspicious noises are heard (hissing);
• of exhaust pipe It turns out too much smoke.

On the diesel engine signs of critical blocks are the same. By the way, the degree of contamination determines the electronics, so the generation of errors can occur in the absence of a strong blockage.

Advantages of regular service

The Syzhevik resource depends on the number of cycles of regeneration initiated by electronics. Frequent cleaning can cause the full burnout of the platinum catalyst layer due to too high temperatures. The main plus of regular diagnostics and cleansing is to save money on installing a new filtering device.

When driving B. extreme conditions Soot is more active. Preventive cleaner will help to avoid the replacement of the node. In addition, the car with a pure Syazhevik consumes less fuel, its motor is more powerful. Is it worth talking about a significant decrease in harmful impurities into the atmosphere? In general, regular service contributes to an increase in the resource of the node and makes it more reliable.

Cleaning the particulate filter should be made during maintenance. Only so you can avoid accumulation of excessive amounts of particulate sediments. There is another way to extend the resource of the filtering device - use additives. They help reduce the activity of the formation of particulate sediments and reduce the temperature that occurs during the regeneration process.

There are additives that add to the diesel fuel so that it burns in full. This leads to a decrease in soot emissions into the system. When using additives, it is often not necessary to clean the SAZHIK - but it is sometimes necessary to check anyway.

Than rinse the scene filter

Cleaners of the company consider quality Liqui Moly.But they are expensive. The tool helps to reduce the formation of Nagar. It is suitable for transport with diesel. Continuous use of cleaning additives will increase the filter resource.

Another effective tool - Diesel PartikelFilter Schutz. One package is enough for 2,000 km. IN fuel tank This substance is added before filling the fuel. It is not recommended to use Diesel PartikelFilter Schutz along with other means. At 75 liters of fuel takes 1 vial.

JLM is also a high-quality remedy for washing the Syzhevik. If you add it every 10,000 km, it will be able to fully restore the performance of the element. JLM can be used on any car.

Russian tool - "Protection". According to the manufacturer, it can reliably protect DPF from clogging. Norma - 1 bottle by 10,000 km run. The substance is added to the fuel tank. The cleaning process starts during the vehicle movement. It does not turn to the elements of fuel and exhaust systems of negative impact. The use of the "Protection" means leads to a significant reduction in exhaust toxicity.

Cleaning the diesel engine filter with their own hands

Washing the diesel engine filter (as well as a gasoline engine) produce 2 ways:

• without dismantling the device;
• after dismantling.

For self cleaning the node, it is removed. The procedure is quite troublesome - takes 8 hours. The filtering device is removed, its housing is filled with a flushing agent. Cleaning fluid is usually sold in 5 liters in canisters. One procedure takes up to 4 liters. Means fill through the hose, which is included with Kanishystroe.

Filling the filter, the substance begins to dissolve the sage sediments. Proper effect can be expected after finding fluid inside the case for 8 hours. Do not neglect reading instructions before applying the tool, as the dosage is painted in it.

After 8 hours, seeded deposits are separated and removed under pressure from the water jet. Then the Syazhevik put in place.

Some drivers think that chemical cleaners may pose a danger to the catalyst, but it is not. In modern additives are contained safe elementswhich only destroy South.

Remember the platinum layer covering the inner part of the Supil. It is rather fragile, and the excessive impact on it is unacceptable.

Flushing of the particulate filter without dismantling

The work will be performed faster if you do not remove the device. It becomes possible thanks temperature sensor. After its unscrewing, a hole appears through which you can fill washing fluid.

Do not forget about safety equipment - remember that the liquid can ignite. The remedy is supplied to the hole using a gun or probe.

Here is how to act:

1. Engine warming up.
2. In the hole fill the liter of the fluid and leave for 15 minutes.
3. Pistol connect with probe.
4. Probe insert into the hole. Spraying fluid takes 10 minutes. Then 10 minutes the procedure stop, then resume.

The ten-minute cycles (cleaning stop) should be 4 or 5. For better spraying of the composition of the probe during the cleaning process, it is recommended to scroll and move forward-back.

After procedures in the system, fuel the rinse (0.5 liters), which is needed to neutralize the remains of the active substance. Rinsing by sprayer with the same time intervals.

At the end of the work, the sensor is screwed into place, the motor warms up to operating temperature. Then launch the regeneration process, which will destroy the remains of the particulate sediments. The duration of the process is 15 minutes. The natural lap of the soot begins after the engine is for some time (15-20 minutes) runs on medium turnover.

The process may not be launched naturally - due to the problems with electronics. In this case, it must be launched independently using a scanner for diagnostics.

Methods of cleaning have their advantages and cons, but it is still better to dismantle the device. And it does not depend on what force aggregate It is worth the car - Diesel or gasoline engine.

The appearance of a diesel engine on the mass consumer market forced the developers of such motors to bring them to world environmental standards. Diesel engines should effectively deal with the spent gases, delaying elements dangerous to the atmosphere. During the modernization of the system of exhaust gases of diesel engines, the SAZH filter DPF was used everywhere, which effectively purify the exhaust. During the operation of the diesel engine, the particulate filter is contaminated and requires cleaning or replacement.

What is a diesel filter DPF: the task and principle of work

How can I understand from the name, the task of the particulate filter is to hold the soot particles when they appear in the exhaust. It accumulates soot, which after surviving, thereby achieved less harmful to ambient exhaust.

The principle of operation of the DPF filter in the following:

1. The filter accumulates soot to a critical moment, which depends on the pressure difference before the filtering element and after it;
2. When this pressure deviates from the norm, that is, the filter bandwidth decreases, the electronic motor control unit receives information and activates the afterburning mode of the accumulated soot;
   Please note: depending on the engine manufacturer, the process of afterburning can be activated under various conditions.
3. The process of afterburning occurs at an increased speed of rotation. crankshaft and enhanced fuel injection, the command to which is supplied by the control unit;
4. Thus, the temperature increases exhaust gases Before the values \u200b\u200bin which the cargo shift occurs.

Despite the presence of the cargo of the soot, nevertheless, it can accumulate in the DPF filter and not burn. This is especially true for drivers who rarely exploit the car at elevated circulation, moving, mainly in the city trait.

Since the cost of the DPF particulate filter is high enough, the drivers need to follow these elements and to clean it in a timely manner in order not to encounter the need to replace it.

Causes of clogging of the diesel engine filter

Saya - Side Product Working diesel fuel In engine cylinders. In the exhaust gases, it is represented in the consistency of the fine powder, which is delayed almost completely with a mesh of the particulate filter.

The operating cycle in the chamber does not burn particles of hydrocarbons that go into exhaust. Because of them begin to form resinous sediments. This resin gluits small particles of soot, which leads to the formation of a car. In a place with a soot in this nagar, there are other elements of the game of diesel fuel, as well as metal sulfates arising in the exhaust due to the combustion of the oil that has fallen into the cylinder.

Please note: metal sulfates are a product of combustion of additives for fuel containing metal elements. Especially many metal-containing additives are in universal oilswhich can be used for diesel and petrol engines. This is one of the reasons why such oils are not recommended to be applied on a regular basis for diesel engines.

The result of the processes described above becomes the formation of a sump nagar with particles of other elements that settled on the filter and do not burn in the cargo cutting mode.

What depends on the service life of the diesel filter

Depending on how carefully the car owner is suitable for clogging the particulate filter, the service life of the element is directly correlated. Also for the service life affects the amount of activation of the modes of carbon sage. The more often the car engine activates the sage cutting mode, the smaller the diesel filter.

Experts are recommended to increase the service life of the diesel filter, especially if the car with a diesel engine is operated within the city, on each then to clean this item. It is especially important to do if there are problems in the engine work, which can lead to the formation of a mass carpet on the filter element.

Please note: a clean sump filter is effective from an economic point of view. If the filter is contaminated, the engine power is reduced, which increases the motor consumption for the movement of the car with the same dynamics.

To improve the service life of the particle filter is possible if you use special additives for diesel fuel.In automotive stores, you can find additives that are aimed at reducing the number of formed by Nagar as a result of the operation of the motor. This is achieved due to the maximum combustion of fuel in the engine cylinders, which leads to a decrease in the amount of soot in the exhaust gases. Use such an additive is recommended no less than 1 time in 3,000 kilometers of car run.

Also, the quality of the fuel used is strongly influenced by the quality of the fuel used on the particulary, so it is necessary to refuel with a high-quality diesel engine to maximize the service life of this element.

How to Clean the DPF Symbol Filter

There are two main methods for cleaning the DPF particulate filter from the car. The first implies the need to remove the filter element from the car, and the second implies the action directly by car. Both ways have their advantages and disadvantages, so consider them separately.

Cleaning the sump filter with removal

Complexity this method It is necessary to dismantle the diesel engine diesel filter, as well as in the duration of the procedure. On average, the filter cleanup will take about 8 hours.

Used for cleaning special fluids Flushing with a sump filter that can be purchased in car stores. It is better to choose the compositions of proven brands, such as Luffe, Pro-Tec, Liqui Moly and the like. These fluids are the compositions of oil components and various additives that are able to dissolve the particulate chuck. Fluids are supplied in 5-liter cannors, on average, the entire canister will need one flushing. The canisters from above can take place for fastening the hose, some of them have a hose bundled. The hose allows you to easily fill the sump filter with flushing fluid.

The housing of the suspension filter must be filled with flushing fluid fully and leave for the time specified in the instructions for applying the composition (about 8 hours). After that, it is enough to wash the water jet filter to wash off the dirt residues, as well as the remnants of the cleaning agent.

Please note: to the wash question with water, it is necessary to come seriously, since the means for cleaning the fuel and can ignite when the exhaust gas is received.

After washing the particulate filter, water remains to be dried and installed in place.

Cleaning the particulate filter without removal

The method of flushing the particulate filter without removal is faster, as work is carried out directly by car. Constructive features The filter allows you to submit a cleaning fluid through a hole to install a pressure sensor or temperature, after removing them.

It is important to note that the other composition is used to clean the particulate filter without removing. This is due to the fact that work is carried out right by car, and there is no possibility to make sure that completely petroleum products will be removed from the particulate filter. Therefore, the composition is used on a water-alkaline basis. With fluttering liquid. The fluid will allow you to neutralize the remaining alkali after cleaning.

To wash the particulate filter without removal, you will need to get a spray gun.

Please note: you can also find the washing fluid in the aerosol cans. For efficient use of fluid in the balloon, be sure to read the instructions for it.

Before washing the carbon black filter, the car engine must be warm up, after which it is necessary to wait until the temperature of about 40 degrees Celsius will be installed in the filter element. This must be done to improve the efficiency of alkaline composition.

Spraying of the composition on the particulate filter occurs under a pressure of about 8 bar. In this case, the spraying process must be interval: 10 seconds the liquid is injected, then 10 seconds need to wait before the inrupt of the new dose. Thus, it will be necessary to enter about 1 liter of cleaning fluid. It is also important to rotate and move the spray probe to clear the scene filter entirely. After the washing with an alkaline composition was carried out, clear water is sprayed in the same way.

After cleaning the scene filter cleaning work, it is recommended to carry out the procedure for downloading the residues of soot, by operating the vehicle at elevated circulation for 20-30 minutes.

The scoring of the particulate filter in diesel engines, occurs in the case of operation of cars on short distances. The filter does not have time to warm up to normal operating temperatureTo fully eliminate the accumulated South. If you have a problem, make cleaning or removing the diesel engine squeeze filter.

Owners diesel cars Must know - if the filter has been hampered, the machine automatically turns on the regeneration function. This means that to achieve a high temperature of exhaust gases into the engine vehicle More fuel begins to be injected. If the regeneration process is not performed for some reasons, DPF (diesel diesel filter) It will be clogged with each trip more, as a result, the efficiency of work is equal to zero.

Process of purification

Cleaning the antique element is carried out in case of serious problems or at the time of maintenance of the car. On the automotive market There are many special preparations to prevent DPF clogging.

The service life is determined by the frequency of the location of the element. If the process is often happening, then a lot of catalyst will be unmanned irretrievably. If we speak scientific language, then a reduction in the working temperature of this procedure and an increase in the run between the burnings is a greater resource of the DPF operation.

The resource of the element is designed for 120-150 thousand km of transport mileage and less often - by 180 thousand. The service life depends on the normal and correct operation of the motor, as well as from the style of driving on the car and the most important - the quality of the fuel filled. Therefore, the use of the element with improper operation of the engine may not reach 100 thousand km.

DPF cleaning process spend at an early stage of component contamination. The procedure is intended to improve bandwidth - it will solve problems with low engine power.

The cleaning of the element can be made inexpensively for a hundred, if the filter just started to clog. Try to get rid of the problem personally if DPF is contaminated at an early stage. The component is a grid that during the operation of the car is clogged with fuel combustion products. Use a special additive for cleaning, which is poured into the transportation tank and is mixed with flammable.

The method of cleaning with the help of adding an efficient and popular method among domestic motorists. But the regular use of counterfeit or additives from a dubious manufacturer may harm fuel system. Buy products recommended by a car manufacturer.

There is another version of solving a problem - removal of DPF. With the detail you need to do the following:

• dismantle, adhering to the actions described in the operating instructions;
• soak the component for some time in a special chemical agent (from 15 minutes to several hours depending on the means);
• blow under the action of high pressure;
• install the item back to its place.

Is it possible to wash?

More and more companies are mastering the technique. So, the owner of the car disappears the need to buy a new element. The undertaking will be not suited to the driver: depending on the manufacturer, the DPF car can cost from 60 to 150 thousand rubles. (17-35 thousand UAH).

Attention!DPF washing can not be done with water, otherwise the engine breakdown is guaranteed! For this, special means are used.

Liquid STEP 1 and STEP 2 and probe

To clean the particulate filter, special cleansing agents should be used, injected through holes on DPF and dissolving combined combustion items. So, the soot is burned directly inside the system. Consider the process by steps:

1. FROM exhaust system Remove the pressure and temperature measurement sensor.
2. Then, through the existing hole, a special probe is entered through which the cleansing solution is sprayed onto DPF. If the filter is not removed from the mounting site, use an alkaline water-based alkaline solution. It is necessary to comply with fire safety.
3. Repeat procedure several times with an interval of 5 seconds and with the same pause. This is done so that the solution began its action. To increase the efficiency of cleaning, the probe rotate around the axis, periodically move it forward-back.
4. Take the washing fluid, another probe and the process repeat with all time intervals. Products after combustion in DPF are dissolved and distributed by cleaner element So, that can be eliminated at the time of regeneration.
5. When the process is completed, and the sensor is set to the place, make a control run in a minimum of 20 minutes with the subsequent start of the regeneration process. Either the procedure will begin automatically with the motor system.

The advantage of flushing DPF is environmental safety. Burned combustion items will not enter the environment, and will be eliminated in the process.

Important!Do not try to do an independent flushing of the filtering element without having sufficient knowledge and equipment! Make the flushing on specialized hundred, where the masters thoroughly know the nuances of the process.

Removal

The new DPF costs a lot of money, especially the filters of the original production. The replacement process does not represent complexity and is to dismantle the old and installing a new element. But domestic motorists carry out such actions rarely. It's connected with high cost details.

Much more often car enthusiasts are resorted to DPF removal - the way to solve the problem of a contaminated component. Its removal will reduce diesel fuel consumption, since the driver does not have to ride from time to time on increased turnover for regeneration. Disassembly of the element will increase the power of the transport and forget about the risk of a failure of the engine as a result of clogging by the filter part.

What advantages gets a driver removing an antique filter:

• errors in B. emergency mode associated with DPF;
• the regeneration procedure will stop, the oil level will not increase, and when moving in traffic jams, there will be no black or gray smoke from the exhaust;
• you will not have to wait for the end of regeneration, if you need to urgently stroke the car, and you do not have to additionally "get out" kilometers for cleaning DPF.

We decided to make with your own hands, perform the process in several stages. Without having experience, do not do it yourself. In the case of an error assumptions, the repair may cost much more expensive.

Soot in the engine occurs as a by-product combustion of fuel. Although its volume depends on the ratio of air and fuel, it is still formed in one or another quantity. Bringing the pollution of the environment by it helps a diesel filter that delays about 97% of all particles in itself. He does not give her to go out, and in the future it is simply burned when the engine is working. Such an effect of burning and is called regeneration.

The device of the particulate filter and the principle of its action

The scene filter has a simple device based on a cellular membrane. It is made of silicon carbide and is a variety of small channels connected by jumpers. The use of such a design and material ensures the following characteristics filter:

Due to this, it is able to fulfill its task for a long time, intercepting miniature particles of soot on the path of exhaust.

The principle of operation of such a device is no different from an ordinary filter. Say particles simply remain in the membrane system without going out. Since all spent gases are passed through this filter, the system is able to block a substantial part of the soot in the exhaust process.

But it is important to remember that the filter is constantly filled with soot particles, which leads to a reduction in bandwidth. To eliminate them, regeneration is carried out, which is provided for by the structure itself.

Signs of clogging of the particulate filter

When the car is working, it is important to maintain the bandwidth of the filtering system. Therefore, sensors defining this parameter and, if possible burning soot in the element, are often built into the system. The problem is that bodies are possible only with a long ride on high revolutionsTherefore, it does not turn on when driving for short and winding distances.

For this reason, riding within the city does not give a chance to regeneration. The burning occurs in the minimum degree, while maintaining most of the zoom in the system.

Tip! Poor fuel quality also contributes to an increase in the amount of soot. If the motorist saves on it, then it is necessary to diagnose the filter zoom.

Therefore, it is important to control the state of the system and follow the possible symptoms of the sampling filter:

• increase fuel consumption;
• reduction of thrust;
• consistently high oil level;
• non-medical work system;
• smoky exhaust;
• it is possible to hiss when driving.

And the main feature to pay attention - the filter icon on dashboard. If she caught fire, it is necessary to urgently go to the diagnosis.

Riding a scored filter is contraindicated for any car. With an abundant amount of particulate precipitation, a breakdown of various elements is possible in the system. Oil clogs, which leads to a decrease in engine performance. Over time, the gas recycling system is destroyed, and in the future the engine itself breaks.

Regeneration of the diesel filter

The principle of regeneration is simple: microparticles, scoring the membrane, are burned at a temperature of more than 500 ° C. Therefore, the cleaning process is to raise the temperature in the system to such a mark so that the exhaust gases can burn pollution. This is possible only with the full load of the engine.

There are two types of membranes that differ in location: FAP and DPF. The first type is located on the removal from the engine, and the exhaust gases cannot sufficiently heat the particles. Therefore, for such a task, the fuel additive is used.

Since the exhaust gases pass a big way from the engine to the cleaning element, they simply cannot burn blockage. Temperatures are not enough for such a task, so it is necessary to increase it. For this, special ceriable additives are applied. Ceria microgranules allow you to warm up the gases to the required plank, thereby destroying the blockage.

The additive itself is a cerium microgranules in a special substance. This form allows you to save your structure before entering the filter. Initially, the gases will only evaporate the shell of the granules, freeing the cesium. When he falls on a heated membrane, it is sharply flammable, raising the temperature of the surrounding gases to 1000 ° C. Such a bar is safe for the system, because the heating occurs locally.

Interesting! Although such a temperature can destroy the ceramic lattice, the duration of heating is minimal. This makes this method safe for the system.

The second type of filters is located near the engine, so necessary level Temperatures are achieved without additional tools. The spent gases almost immediately fall into the filter, thereby burning the blockage and continuing its path.

Such a cleaning procedure occurs only in full speed, so it is important to periodically squeeze the engine on full power. But it is worth remembering that the regeneration does not need to be carried out daily, the frequency depends only on the intensity of soot formation.

Forced regeneration and cleaning manually

If the filter was used in adverse conditions, thereby clogging, then use it is prohibited. He simply destroy the system and the engine, which will turn into overhaul. Therefore, with full blocks, it is necessary to undergo a procedure for forced regeneration.

Forced regeneration can be launched with special equipment, often present in service centers. It allows you to quickly eliminate the zoom by connecting the cleaning system. However, it is not always possible to enable it. In cases where the filter is filled above the norm, the cleaning system will not be turned on.

If this happened, the washing will help here with special means. Often it allows you to eliminate most of the soot, after which it is possible to connect regeneration.

Flushing is carried out by two methods:

• without removing the element;
• full flushing with removal.

In the first case, you need to take a spray gun and a flexible tube, as well as a filter cleaning agent. Tunap MP 131 is suitable for such tasks. The pressure source is also needed - compressor. Access to the filter is carried out through a pre-removed temperature sensor or pressure. It is necessary to thoroughly clean this element, approximate consumption per cleaning - to a liter of liquid.

Next, it is necessary to eliminate the liquid with the Tunap MP 132 concentrate. After that, the cleaning procedure is complete, you need to return the sensor to the place and regenerate the filter by regular methods. If the procedure does not help, it is necessary to carry out a complete flushing with the removal of the item.

The second method is to complete the filter and flushing it. First you need to remove the filter from the system and open it. Next it must be washed through special means like DPF Cleaner. They eliminate the remains of soot and oil, as a result of which those easily eliminate under water pressure. Such cleansing agents are washed off with water. Cleaning can be supplemented with special cleaning agents like Pro-Tec Dpfcatalyst Cleaner. However, it depends on the situation.

Tip! The use of the compressor can increase the filter cleaning efficiency. It is enough just to push the cleaner with pressure of compressed air.

After completion of the procedure, you need to dry the filter and install in the car. Then it is worth checking its condition and run regular regeneration. But it is worth considering that not always washing capable of helping against blockages. If available methods did not help, you will have to acquire a replacement.

Important! When using flushing means you need to wear gloves. It is important to remember that these are aggressive substances capable of harming the skin.

Replacing the filter is recommended for passing 180 thousand kilometers. This point can be pulled out by cleaning and regeneration, but the eternally this element cannot serve as the use of a clogged or poor filter will result in a sage in the system, which will definitely fall out in high repair costs.

And for a better understanding of the effectiveness of the washing of the particulate filters, it is recommended to see this video. Cleaning segment clogged filter Using the LUFFE tool. The stages of the procedure and the effectiveness of such washing are clearly shown:
