Technology & How it works

Installation of an SMF^® sintered metal filter and the systems based on it is quick and simple. HJS diesel particulate filters are exceptionally reliable in operation and also benefit from a long service life. The pocket-type construction of the SMF^® prevents clogging such as that familiar, for instance, from conventional ceramic filters with their honeycomb structure. The HJS filter system requires neither extra regeneration aids nor additives or any intervention in the engine management system. Electronic monitoring constantly guarantees the complete operability of the filter. Its modular design also minimises servicing and maintenance costs.

The CRT^® (Continuous Regeneration Technology) effect continuously frees the filter from the deposited soot

HOW THE FILTER WORKS

The hot exhaust gases from the engine – which contain soot particles – are fed into the filter housing and through the SMF^® sintered metal filter developed by HJS. The gaseous components flow through the microscopic pores of the filter pockets; the soot particles, including the ultra-fine particles, are trapped on the surface and deposited on the individual filter pockets.

Electronic monitoring constantly guarantees the complete operability of the filter system

FILTER CLEANING

The CRT^® (Continuous Regeneration Technology) effect is used to break down the soot that collects in the SMF^®. The HJS system combines a highly efficient, upstream diesel oxidation catalyst (DOC) with an SMF^®. Optimised tuning of the system results in the filter being continuously and effectively freed from the deposited soot.
