The emulator is designed to completely remove the particulate filter on diesel engines with Common rail injection system. Diesel cars meeting the requirements of the Euro - 4 standard and equipped with particulate filters appeared in 2001. The Euro-4 standard itself has been operating in Europe since 2005, the Euro-5 standard has been operating in Europe since 2009. This device allows you to play all the signals associated with the particulate filter.
Advantages of the FAP / DPF particulate filter emulator:
- - You significantly save on replacing the particulate filter (The cost of the filter starts at $ 1,000);
- - You get a certain increase in power by reducing the resistance to exhaust gases;
- - Reduced fuel consumption due to changes in the regeneration period;
- - The particulate filter will never bother you again;
- - The control unit does not open when installing the emulator.
Symptoms of a defective particulate filter
The driver usually learns about the existence of a particulate filter (FAP / DPF) after the appropriate indication appears on the instrument panel. Failure of a diesel particulate filter usually entails a decrease in power and an increase in fuel consumption, smoke, and unstable operation of a diesel engine. When reading DTCs, error code P2002 “FAP / DPF Low Efficiency” usually appears.
Particulate filter principle (FAP / DPF)
Reducing the amount of harmful emissions is achieved both due to the design features of the engine with the common rail system, and using a diesel particulate filter. On most modern diesel vehicles, a particulate filter is structurally combined with an oxidizing catalyst. An oxidizing catalyst is located in front of the filter. Thus, the functions of both the FAP / DPF filter and the catalyst are fulfilled.
A particulate filter traps soot particles contained in exhaust fumes. The function of the catalyst is to oxidize the hydrocarbons (afterburning unburned fuel), as in a gasoline engine.
For the diesel particulate filter to work correctly, a lot of sensors and those functions that are absent in the gasoline engine are involved in the car's control system.

The FAP / DPF filter is usually installed in close proximity to the turbine.
The filter is a ceramic matrix enclosed in a metal housing. It is permeated with inlet and outlet channels. The filter walls are made of porous silicon carbide coated with excipients. The walls trap soot particles, and the gas passes through the channels freely.
During operation, a large amount of soot accumulates in the particulate filter, which prevents the free exit of exhaust gases. Therefore, from time to time, you need to periodically osfobodait filter from soot. The process of releasing the filter from soot is called regeneration.
There are active and passive regeneration of the particulate filter. The regeneration process for the driver is not noticeable.
Regeneration types depending on the degree of filling of the FAP / DPF filter
With passive regeneration, the soot burning process is carried out continuously and without interference with the engine management system. Passive regeneration is possible mainly with engine loads above average, when the temperature of the exhaust gases in the filter reaches 350 degrees or higher. With passive regeneration, chemical reactions of the conversion of soot to carbon dioxide occur. The acceleration of these reactions is carried out using a layer of platinum, which acts as a catalyst.
The control unit constantly monitors the degree of clogging of the filter with the help of temperature sensors, differential pressure and air flow. Upon reaching a critical degree of contamination, the control unit starts active regeneration.
The essence of active regeneration is to artificially increase the temperature in the particulate filter to 600 degrees or more. Achieving this temperature is possible with directional engine control.
To increase the temperature of exhaust gases, the control system performs the following actions:
- Exhaust gas recirculation is stopped to increase the temperature of fuel combustion;
- An additional portion of fuel is injected when the crankshaft is rotated by 35 degrees. after TDC;
- Using the throttle, the air supply to the engine is reduced;
- Another additional fuel injection can be made, while the fuel does not ignite in the cylinder, but burns directly in the FAP / DPF filter;
- The boost pressure is maintained at such a level that the driver could not notice the transition to the regeneration mode.
