What To Expect From a Diesel Particulate Filter
Diesel particulate filters are now very much the norm on many diesel cars, vans and lorry’s (in fact, some countries now have laws in place that make it mandatory for new diesel vehicles to come with these filters already installed). What they help to do is reduce the amount and frequency of harmful chemicals being emitted into the atmosphere and into the faces of the general public whilst the engine is running. The filter itself is a vacuum that traps the likes of soot etc… and stops it from escaping from the exhaust and therefore significantly reduces the risk of ill health to those who happen to breathe in the fumes.
Some of these vacuums and filters can help to reduce the emissions by over 80% and this can have a tremendous effect on the environment as a whole and also to our general health. One of the big parts of DPF removal is the regeneration process that helps to clear the filter of all the accumulated and excess soot. This can be done in two ways. The first method is to passively remove the excess by the engine removing it while it is in usual operation through the warming up of the filter. This is generally what happens on long journeys as the engines heats up more and more and therefore helps to remove the accumulate particulates.
The second method is the active method and this involves manually introducing a high temperature to the filter itself in order to clear it of the soot and grim that is has built up during use. The kind of filter you use can have a large bearing on how this is done because there are certain types of filters that are far better suited to the slow, building up of heat as opposed to a quick blast.
