If you read our diesel tuning article, race parts then you probably want to know more about the particulate filters. Particulate filter is a separate device. It is located upstream of the cat in the exhaust system and its purpose is to remove soot particles from the gas stream.
Cat proceeds to make its normal operation to convert CO to CO2 and is in no way dependent on or referenced particulate filter.
The diesel cats and two devices by work in an unregulated mode (ie O2 sensor as gasoline vehicle). Gasoline cat 3-way closed loop controlled devices, although in principle the same.
Diesel engines are much more efficient that their gasoline counterparts and release less CO2, but the diesel exhaust gases are black and sooty as the attempt to solve the diesel particulate filter.
With a diesel particulate filter to do and does it affect performance?
Most filter systems require some type of fuel catalyst mixed with the fuel. This occurs automatically whenever the filler off the machine detects the amount of fuel added and then controls the appropriate additive makes the fuel tank itself.
This additive is kept in the vessel close to the fuel tank and requires periodic refueling, typically every 50,000 km. billet crankshaft PSA vehicles use an additive made by Rhodia Inc (formerly Rhone-Poulenc), its brand name Eolys. The additive reduces the carbon combustion temperature, so that soot may be cleaned from the filter intermittently. This process is known as regeneration.
Regeneration starts automatically when the pressure sensors on both sides of the FAP (filter) detect the pressure drop due to partial lock (for blacks). During this process, the number of things:
1. Intercooler costs
2. Glow plug switch
3. Additional fuel is injected into the combustion chamber during the expansion phase.
This creates lots of heat. So much in fact accumulated soot literally burns. In my opinion, this is equivalent to the horizontal fire tube and probably as dangerous as one.
This process may be triggered manually by a specialist who has access to the appropriate diagnosis. This is called a forced regeneration may occur when the vehicle is stationary in the workshop. In this situation, in addition to an intercooler / fork / after injection engine speed itself is about 4500rpm 40 minutes to burn off soot. There are rumors flying that it creates so much heat from the exhaust it has been known to burn painted floor studio.
I was told that some systems work without a fuel additive, but the principle is the same.
So, no, the particulate filter is not a cat. No, you can not get a sports one – its job is mainly to filter out large particles in the air from your exhaust.
Technically, you can delete it, but you will have to reprogram the ECU does not pay attention to the pressure sensors, otherwise the system can go into emergency mode home with fault lights everywhere.
My car is equipped with FAP, and, in my opinion, this technology is too far. What’s the point to get rid of a bit of smoke and replace it with very very carcinogenic compounds cerium?
As regards particulate filters, turbocharger manufacturers and performance they are normal – Peugeot Le Mans car used them. I said, however, that, if I took it with my reassigned 406 (192 hp now) it will go to almost 200! So to summarize, they are a necessary evil. They are not suitable for productivity. But I wonder how much my shit will spew without him? I’m at least that warm fuzzy feeling that I did not contribute to the suffering of asthmatics across the country.
