If a fuel-borne catalyst (FBC) is used as part of the regeneration strategy, then making sure that the dose is correct is very important. If it is too low (or if the requirement for the FBC is simply forgotten), then the filter may fail to regenerate leading to blockage and potential damage both to the filter and the engine. Conversely, if the dose is too high then excessive amounts of ash will accumulate in the filter, requiring more frequent cleaning. In order to avoid these problems, Blackthorn can supply an electronic dosing system comprising a small tank for the FBC, a dosing pump and a controller. This system is easy to install and, once calibrated for a particular application, will ensure that the dosing level is correct and that the particle filter regenerates as intended.
