Eberspächer diesel particulate filter - fork lift truck as example of use

Modern Eberspächer particulate filters are used in commercial vehicle engines of every type and ensure a dramatic reduction in emissions even in fork lift trucks. More than 90% of the particulates can be filtered out and burnt in the filter - including many superfine particles featured in the press these days.

Thousands of channels

With their characteristic honeycombed structure, consisting of innumerable channels arranged in parallel, particulate filters are similar to ceramic catalytic converters. Silicon carbide (SiC) and cordierite perform the best service as ceramic materials.

The filtering process

In the filtering process the exhaust gas flows through the porous ceramic walls. The particulates are transported by diffusion to the pore walls and remain trapped there. With increasing loading of the filter with particulates, a particulate layer also forms on the channel walls.

Regeneration of the filter

One of the main tasks of particulate filter technology is to ensure the effective combustion of the accumulating particulates - therefore effective regeneration of the filter.

In fork lift trucks standby regeneration has proven to be especially effective. This means that the particulates accumulating in the filter are burnt off during operating breaks - by a diesel burner integrated in the system.
