Daily filter - what is he needed and how to care for him?

For many people, when they hear the phrase "Symbol Filter", immediately goosebumps, and unpleasant memories arise before their eyes. Is the design of the particulate filter successful?

This filter is installed only in diesel engines and is designed to purify exhaust gases from particles of soot and ash. Depending on the brand of the car, it can be found under two names: DPF (diesel filter) or FAP (solid particle filter). Their use in passenger cars is intended to eliminate black smoke emissions characteristic of cars equipped with a diesel engine. The filter is one of the components of the exhaust system. Most often, it is located immediately behind the catalyst.


In short, the particulate filter is a metal jar with special channels inside. The filter housing is made of stainless steel, which is very resistant to harsh working conditions. Inside the filter there are channels of a small diameter located in parallel to each other. Each of them has one closed end - alternately: one on the side of the entrance and one on the exit side. The result of this processing is the creation of the grid, and therefore the exhaust gases should penetrate the porous walls so that they can go out. The walls are made of silicon carbide coated with aluminum oxide and cerium oxide, and in many cases they are additionally applied platinum particles.


In most cases, filters used in our cars can be restored. Of course, there are disposable filters that are subject to expensive replacement after fill. Filters of solid particles that can be restored are divided into two types: a wet filter and a dry filter. In the case of a dry filter, there are two types of recovery: active and passive. Passive occurs without the intervention of the engine controller and occurs when the temperature of the exhaust gases is reached in the range from 350 to 500 degrees. Active occurs only when the engine controller intervention is interfering and occurs at a temperature of about 600 degrees. With passive, the recovery of soot reacts with the filtering material. The result is cleaning the filter. Active recovery takes approximately 5-10 minutes and is carried out approximately every 200-600 km. On-board computer reports the need for recovery. At the same time, the soot accumulated in the filter simply flashes. The restoration of wet filters is carried out by regularly adding to special fluid fuel. It significantly reduces the temperature of the burning of the soot, which makes it possible to restore the filter.
