These particles essentially contain carbon with a size between one micrometre and 10 mm. The principle of particulate filters consists in storing and destocking filters emitted by Peugeot car engines. A temperature of at least 550°C is required to properly dispose of them. However, engines only achieve this condition when the car makes long journeys on motorways. In the city, the temperature is below 150°C with a speed of 50 km/h. Also, regeneration must be carried out regularly in order not to damage the particulate filters.
The different technologies of particulate filters
There are two particulate filter systems on the market and each uses projection at the combustion zone where the gas is heated. The difference between filter types is in the regeneration process. You will find several types of Peugeot particulate filters on krosfou.fr/. The fap models for Peugeot 807, fap for Peugeot 508 and fap for Peugeot 607 are in an independent tank. This is a major innovation since the mixture of cerium oxide and iron oxide creates a catalytic effect when it meets soot. Oxygen is released into the core of each particle to accelerate combustion. This is even when the required temperature is not reached. This process promotes a rapid regeneration of less than 5 minutes. It limits over-consumption of fuel. The only disadvantage is that you must fill up with Ealys when the car has driven 120,000 km. Ealys is the name given to the mixture of cerium oxide and iron oxide. The second technology has made it possible to develop the oxidation filter whose walls are covered with precious metals such as platinum. The latter have a catalytic effect when they meet soot. This implies that the regeneration of the particles is carried out at a temperature of at least 650 °C for at least 20 minutes, resulting in high fuel consumption. Additional devices have been added to accelerate regeneration, particularly in cities.
Types of problems on a particulate filter for Peugeot
Problems can occur with the particulate filter for Peugeot 508. Indeed, it is difficult to create all the conditions for good particle regeneration. Many vehicles are equipped with a FAP that is not optimized when they make a short trip. The temperature required for the destruction and regeneration of the particles is therefore not reached in these cases. This inevitably leads to clogging of the particulate filter for Peugeot 607, so that regeneration is no longer possible after a certain time. Vigilance is required regarding the various symptoms of failure indication of the particulate filter for Peugeot 807. You will notice that there is a loss of power in the engine or that an indicator light on the dashboard keeps flashing. This system applies to all vehicles equipped with an electronic dashboard. You will also notice that the particle filter works, but in degraded mode. Sometimes you get stuck for no apparent reason or your engine chokes because of a clogged or clogged particulate filter. In all cases, it is preferable to contact a professional mechanic directly. He performs an adequate intervention to force the regeneration of the particles in his workshop. The only solution may be to replace the faulty equipment. You should also know that diluting the oil or using a poor-quality product can damage the particle filters because of poor lubrication of the turbo. Other reasons may explain filter damage such as malfunction of injectors, flowmeter, thermostat or because there is oil in the intake system. Therefore, it is important to always contact a qualified and experienced garage because solving this type of problem is a real brainteaser.
The frequency of replacement of particulate filters
In general, the service life of a particle filter corresponds to that of the car. However, its longevity depends on many criteria such as driving style (city or highway), quality of maintenance, frequency and effectiveness of regeneration. All these factors can cause premature replacement or clogging of the APF. It is very important to always refer to the manufacturer’s recommendations for verification periods. For additive APFs, the service life depends mainly on the year of the car. It should be noted that Peugeot has developed many types of particulate filters. Innovations have made it possible to have a longevity between 80,000 and 210,000 km. In any case, you must request a systematic inspection from your garage for preventive maintenance. Consider the part numbers of the spare part you are going to buy to be sure that it is compatible with your car. Also, the removal of AHF is prohibited by law because of the health risk posed by particulate matter.
Maintenance to be done on the particulate filter
It is quite possible to clean and maintain the particulate filter before considering its replacement. There is an effective technique using hydrogen combustion to minimize the level of fouling. It is best to make trips to reach the temperature necessary to start the regeneration process immediately after the garage intervention. This method promotes a better regeneration and your car regains all its performance. You won’t have to worry about the black fumes coming out of the exhaust pipe, the engine stalling or choking. It is recommended to carry out descaling at each maintenance to ensure that the engine is in good condition and the particulate filter is working properly. To avoid clogging, it is possible to apply certain tips. City dwellers and those who rarely use their cars can travel long distances on the highway for 20 minutes at least once a month at a minimum speed of 3000 rpm. You will avoid going to the garage for forced regeneration. It is also very important to ask your dealer for advice before using an engine additive or biofuels. Note that it is not recommended to switch off the engine after a heavy load, as this increases the temperature and can cause damage to the particulate filter.
