Research on Diesel Particulate Filter Regeneration Equipment Based on LPG

Abstract

This paper give a LPG (Liquefied Petroleum Gas) burning regeneration DPF(Diesel Particulate Filter), which the filter bodies of both the DPF were made of winded metal mesh, to fit for the high sulfur diesel. The DPF were re-designed and optimized according to a long time bus installation in-situ experiments. The LPG burning regeneration DPF could trap the most part of the particulate matter (PM) (85% at maximum) and did not have noticeable effect on engine performance. Development of performance external LPG heating regenerative devices can be completed within 20 minutes DPF regeneration. It is cheap, good durability, a high degree of confidence. Because they do not use the catalyst can be regenerated, so it can be used in high-sulfur diesel.
