Ceramic Diesel Particulate Filters

A dpf typically uses a substrate made of a ceramic material that is formed into a honeycomb structure.

Ceramic diesel particulate filters.

Dpf is a device designed to remove diesel particulate matter or soot from the exhaust gas of diesel engine vehicles the dpf filters first trap particulates and then use a catalytic technology to continuously burn them at normal diesel operating exhaust temperatures. Cordierite material which is raw material molding and synthesized cordierite after burning cordierite dpf filters are one of. In order to satisfy environmental regulations that should become increasingly strict in the future. These openings trap soot on the channel walls and prevent it from exiting the exhaust tail pipe.

With an optimal diesel particulate filter dpf soot emissions may be decreased to 0 001 g km or less. New particulate filters can capture from 30 to greater than 95 of the harmful soot. For example a high sulphur content diesel produces more particles. Corning duratrap particulate filters offer monolithic design and advanced material compositions to optimize pressure drop filtration efficiency durability and system cost.

The quality of the fuel also influences the formation of these particles. It has a series of small honeycomb shaped openings covered in palladium or platinum. Twenty five years of diesel particulate filter dpf developments have shown that ceramic materials are well suited candidates to fulfill the harsh requirements of exhaust after treatment. Jintai cordierite diesel particulate filter hereinafter called dpf is designed to remove black smoke soot hereinafter called pm form diesel engine exhaust making great contribution to clean the exhaust gas from diesel cars while attracting much attention from worldwide car manufacturers.

A diesel particulate filter or dpf is an exhaust aftertreatment device that traps particulate matter such as soot and ash.
