DPF COMES CLEAN: TrapBlaster 7 corrects for failures in traditional methods

摘要

The Diesel Particulate Filter (DPF) has proven a huge success in removing soot particulate matter from the exhaust stream since the 2007 EPA emissions mandate went into effect. The good news is these vehicles no longer belch black smoke and leave the stench of diesel fuel in their wake. The bad news, according to Drew Taylor, president of FSX Inc, Granite Falls, WA, an industrial filtration cleaning company, is that the DPF is more fragile than originally thought and requires some careful maintenance of its own. "In the case of the DPF, the designers anticipated the gradual buildup of ash deposits in the filter," Taylor says. "Unfortunately, the tools to correct this condition were almost an afterthought." He says once the mandates came out following an "endangerment finding," and EPA then implemented its emission reductions in successive stages. OEMs and vendors went scurrying to incorporate the best available methods for achieving compliance.
