The strong contamination of the particulate filter adversely affects the performance of the entire vehicle, and which car owner will like that the car has noticeably increased fuel consumption, the thrust decreased, and also all the time annoying checklists. Of course, the question can be solved by replacing the part, but for this it will be necessary to pay a fairly decent amount. The only reasonable way out in this situation, from the point of view of most motorists, is the complete removal of the filter from the car, but not everyone thinks about possible consequences. About this further in the article.

Dairy filter, as it works and why it is needed

The diesel particulate filter is an important element of the exhaust system of the diesel engine. The task of this device is to clean the exhaust gases from soot to prevent them from entering the environment (about 90 percent does not pass out).

Use the sage filters began in 2001 on trucks. However, after the introduction of the Euro-5 environmental standard in 2009, all automotive manufacturers have obliged to establish this filter element on cars of any type and class working on the diesel.

The diesel filter is made in the form of a metal cylinder. The cylinder is located output and inlet nozzles for connecting to the general system for cleaning the exhaust gases. Inside it is a ceramic matrix. In addition to her, sensors that control its operation are mounted on the scene filter. Depending on the design, the diesel filter can be mounted differently.

The principle of operation of the diesel filter

Functional filter functions in two stages:

Stage 1 - Capture of soot. Saw particles at this stage are settled on the walls of the filter element, which resemble cells in appearance. Soot, while it does not remain completely, but only particles are greater than 0.5 μm. The rest comes out with exhaust gases, although the percentage of such precipitation is small - about 10 percent.

2 Stage - Regeneration. The time-consuming procedure for cleansing the cells from the particulate precipitation. The process passes according to the regulations prescribed by the manufacturer.

Methods for cleaning the size filter

There are two methods for cleaning the particulate filter - active (forced) and passive.

Passive regeneration is carried out by a car owner independently when an appropriate indication occurs and with notable symptoms of deterioration of the power unit (reduction of the dynamics, a drop in power, and so on).

The most important thing is to ensure an increase in temperature for exhaust gases, which can be obtained if you pass with a full load of thirty-forty kilometers. This movement mode provides combustion of soot and cleaning it. Alternatively, you can still use special additives into fuel, which lead to a decrease in the combustion temperature of the soot.

Active regeneration. Such a mode that allows you to clean, can automatically turn on the motor control controller, for which it analyzes the information that the current temperature sensor transmits it and the pressure difference sensor. This sensor indicates that the particle filter is clogged with particles of soot, and using the current temperature sensor, its value is determined. If the temperatures are not enough for soot to burn, the controller can produce, for example, an additional fuel injection produced during the release of exhaust gases, which will result in combustion directly in the exhaust system, and also increase the temperature of the exhaust gases to the desired value.

If the exhaust system installed on a diesel engine provides other measures aimed at increasing the temperature of the exhaust gases that enter the diesel filter, the control controller also uses them.

How does the scene filter differ from the catalyst

The particulate filter is designed to prevent / minimize the ingress of soot into the environment. It is considered part of the muffler and its main task is to clean the exhaust gases. But, it is not necessary to compare this device with a catalytic neutralizer, since the catalyst is struggling with exhaust gases, and the diesel filter is only with the soot in them.

Positive Moments of Diesel Operations with Syft Filter

To the positiveness of the operation of the diesel engine with the diesel engine, the car compliance with the Euro-5 environmental standards can be attributed. The vehicle does not pollute the atmosphere, and people no longer have to breathe sozhai.

Negative moments of diesel operation with a sump filter

There are a number of negative factors arising from the use of a sump filter:

1. Increased fuel consumption.
2. Significant maintenance and replacement costs.
3. Personal time loss due to the start of regeneration (if it started, it cannot be interrupted) and the car service.
4. Systematic deterioration of the characteristics of the car as a result of reducing the bandwidth properties of the filter.

If the diesel filter is output, positive and negative moments

Advantages of removal of the scent filter:

• There is no need to maintain the filter element.
• Power unit works more stable.
• Improving dynamic vehicle indicators (power increase).
• Reducing fuel consumption.
• The need for regeneration mode disappears.
• No emergency mode of motor and errors due to the scored filter.

Disadvantages of the removal of the scent filter:

• Deterioration of environmental indicators. Although the inspection can be passed, the level of soot emissions into the environment is sharply rising.
• The car is deprived of warranty (if available).
• Increase the load on the turbine, which reduces its resource slightly.
• In some cases, an increase in the number of black smoke from the exhaust pipe occurs.
• Problems with the operation of a car in the countries of the European Union, where all cars must comply with the Euro-5 environmental standards.

Stages of removal of the particulate filter

The process of removing the particulate filter consists of two steps - physical and software.

physical stage of removal (step by step)

The physical stage is easy. The masters find the bank where the catalyst and the filter are located, and cut it out. On some models, there will be a removal of the exhaust pipe for this. Instead of the filter, you need to deliver anything, for example, conventional metal plugs or plane sensors. The installation of the flamesteller will slightly increase the life of the muffler. If the element is equipped with carbon dioxide probes and temperature sensors, they will need their withdrawal and mounting into the cap, which makes it possible to avoid program errors.

It is extremely recommended to remove the diesel filter yourself. The probability to break something very high. The process itself occurs as follows:

1. First, disconnect the sensors and cut the exhaust pipe with the help of the grinder, located after the filter.
2. Then we unscrew the bolts from the motor side, cut and open the filter's trim.
3. Let's get the device itself. It may be necessary to knock out separate segments.
4. Brew the case and install it in place. Connect the sensors.

reprogramming of the engine block (moving methods)

After that, you should reprogram the power unit block. If you do not do this, the sensors will assume that the filter is constantly scored. The result is a demonstration of fault codes, and sometimes an emergency mode is turned on at all.

This part of the procedure is carried out only by the experts of the service center. The result can be achieved by three methods:

• Install the firmware from the manufacturer of the vehicle. This is the best option that does not actually carry any risk.
• Install the firmware developed by enthusiasts. This is a kind of lottery - not the fact that you are lucky. The quality of the firmware varies very much.
• Install the firmware from the vehicle version, where the default is the diesel filter. The method is fraught with a decrease in functionality, for example, a cruise control is turned off on Honda CRV.

In some Ford, Mazda, Toyota and Nissan models, it is impossible to complete the usual flashing - you have to apply the method of emulation. The device is mounted, which causes the unit to assume that the filter is in its place. The controller does not notice the seizure of the element, since the corresponding signals receives. But this option has one disadvantage - the regeneration mode will be completely inclusive, so that the fuel consumption will not decrease.

Possible risks who are subjected to a car when conducting the above works

First, with the independent removal of the particulate filter, there is a risk of something to break, which will entail even big problems, and the cost of repair will increase significantly.

Secondly, if the motor block is incorrectly reprogrammed, the system will see that the filter is not clogged, and this simply cannot be, so it decides that the diesel particulate filter is faulty, and translates the vehicle into an emergency mode, not to mention that The system will constantly issue malfunction codes.

Thirdly, many motorists say that after removing this device, the dynamics of the machine is improved. The reason is obvious - as a result of removal of the particulate filter, the resistance of exhaust gases is reduced. However, is it good? Due to the increase in the speed of the exhaust gases, the speed of rotation of the turbine increases, which, in this case, exceeds the calculated speed. As practice is evidenced, often after seizures of the particulate filter, a turbine is out of order.

Council Profi: Trust the work of professionals

Do I need to remove the sump filter? To solve only you. The car really becomes easier and cheap in operation, power increases slightly. But it is necessary to order this event only from highly qualified specialists, otherwise you can get more trouble than good.
