DPF solutions
WHAT IS THE DPF SYSTEM WHY USED?
The diesel particulate filter is a part that gives a lot of users a headache as it gets clogged frequently and the vehicle malfunctions. First of all, we would like to share the problems with this piece and its solution.
The diesel particulate filter (DPF) is a part of the engine exhaust system used to meet the emission requirement. The working principle of the diesel particulate filter is to keep and trap the particles harmful to the environment. While it is available in some Euro 4 vehicles due to emission standards, all Euro 5 and Euro 6 vehicles have diesel particulate filters.
WHAT ARE THE CAUSES OF DPF SYSTEM FAULTS?
DPF and EGR get clogged over time, especially with the use of poor quality diesel and engine oil that does not comply with the standards. When the blockage reaches a certain level, the vehicle's display gives an engine failure warning or a particulate filter full warning and engine power is restricted.
Using low quality fuels
Prolonged driving in heavy traffic
Prolonged driving at low speed
Leaving the vehicle idling for a long time
Engine oil burning
Filter clogging with fine soot due to high mileage
Failure of sensors preventing DPF regeneration
Engine problems such as injector leaks, valve stem oil seal leaks, worn piston rings
Frequent city and short distance uses
Poorly made tuning practices.
WHY CANCEL DPF SYSTEM?
The DPF system, which is built to protect nature and the atmosphere, has advantages as well as major disadvantages in some cases. The biggest problem is that this system is clogged and malfunctions and it is not possible to repair it. Vehicle; When the DPF reaches a certain 'fullness' level, it performs a regeneration cycle to burn off the particulate matter inside the filter. When the ECU initiates a regeneration cycle, it burns a small amount of fine soot before the particles are completely removed from the filter. Over time, the fine soot content builds up to a point where a regeneration cycle can no longer yield benefits, at which point the filter becomes clogged and must be emptied or replaced.
As with every part in the engine, the Particulate Filter has a design life, but this life is approximately 75,000 km in our country due to fuel quality. However, this can vary greatly depending on vehicle use and engine condition.
Changing this system can start from 3000-4000 TL for B class vehicles and go up to 15.000 TL depending on the class and the price of the vehicle. If it is not repaired, the fault lamp constantly lights up as a result of the filter clogged, the valves can be damaged by backpressing the engine due to the blockage, or the engine is knocked out by missing the time setting, and even in some vehicles, the vehicle deliberately restricts its own power (up to 30%-40%) because the DPF system does not work, and some It is known that the vehicles do not work because the filter is full. Since it is known that the repaired or replaced system will not be as compatible and trouble-free as the system installed at the factory, and due to high replacement costs, most people in our country and in many parts of the world prefer to cancel it.
As a result of the cancellation process, the emission standards of your vehicle are converted to Euro 4 level. As a result of our Ecu software prepared by our engineers, you do not experience any problems in the exhaust emission inspection. As the engine system provides more comfortable air flow as a result of the process, its benefits in power and fuel consumption have both been proven and confirmed with customer feedback.
