Different Types Of Diesel Filters
Diesel particulate filters have really changed the way we view diesel based engines and have, also, ensured that the emissions from these engines are far lower than they were in previous years meaning a much healthier and better environment for us all to live in. Many government’s now insist that these filters be attached to every new diesel based vehicle such is their beneficial and health related nature.
There is not just one filter, however, that acts for the purpose of DPF removal, there are, in fact, several different variants of the diesel filter that are used in different circumstances. Firstly we have the Cordierite filters that are a ceramic based filter and are the most inexpensive type to use. They are very effective however, although they do suffer from a low melting point meaning that, during filter regeneration, they can become damaged and need replaced.
Next we have the Ceramic Fibre filters that are great for being shaped to fit any device or design and they also benefit greatly from having a lower back pressure which gives them a particulate removal average of 95+%. The Silicon Carbide Wall Flow filters are, after the Cordierite ones, the second most commonly seen filter type. They have an advantage over the Cordierite filters by being able to sustain more heat and have a higher melting point although they tend not to be as stable or reliable as the latter. Lastly we have the Metal Fibre Flow Through diesel filters and, as they are metal based, have the option to pass through an electrical current. They are usually the most expensive type of filters used for diesel particulate removal however are generally considered to be the most reliable and effective when it comes to cutting down on the emissions that are expelled from diesel based engines.
