Summary

In some Euro IV commercial vehicle applications as well as in larger quantities as a retrofit solution for diesel cars partial flow filters are already in the market. A stage IV non-road application on an engine with mechanical fuel injection has shown that with an appropriately optimized partial flow sintered metal filter (pSMF®) significantly higher PM reduction rates are possible than in the first-mentioned applications with a maintenance free particulate reduction system. After a short introduction to the basics of partial flow particulate filters this paper describes the possibilities to achieve significantly increased PN reduction. With the achieved PN reduction level of about 75% to 85 % of this development it seems feasible to achieve the particle number limit for emerging non-road stage V limit with a further developed partial flow sintered metal filter.
