A diesel engine generates diesel particulate matter<\/strong>\u00a0or\u00a0soot\u00a0<\/strong>every time the pump releases more fuel than it can be burnt at a given moment (for example during a sudden acceleration).<\/p>\n

Following injection, diesel fuel is nebulized into small drops. Some of them won\u2019t burn completely, but only partially, creating fine dusts with a size of the order of microns. The temperature of the exhaust gas is not enough to burn this uncombusted fuel, which eventually flows towards the exhaust pipe to be released.<\/p>\n

The soot\u00a0is therefore mainly formed by carbonious material, which needs to be burnt (oxidized) to be removed. This process is called regeneration.<\/p>\n

The two ideal conditions for the oxidation to take place, are the presence of oxygen and a temperature of about 600\u00b0C.<\/p>\n

However, since the typical diesel car engine operates at about 300-400\u00b0C, these two conditions can be recreated in two ways:<\/p>\n

    \n
  1. By increasing the temperature of the exhaust gasses.<\/li>\n
  2. By lowering the temperature required for the oxidation with the help of catalytic fluids (Eolys).<\/li>\n<\/ol>\n

    However, whenever the process is not completely successful, most of the dusts will remain in the filter, blocking the pores. With a clogged filter, there are two possible solutions: replacement or regeneration.<\/p>\n

    Under no circumstance is washing the filter recommended, because water or other cleaning liquids will simply flow through the unblocked pores, leaving the clogged ones untouched.<\/p>\n
