2017/11/5· In theory a DPF needs no maintenance - it’s just a steel chaer up near the engine full of Cordierite or silicon carbide designed to trap microscopic soot, and then periodically the computer
2015/6/15· 1. Introduction Since 2009 wall flow DPFs (Diesel Particulate Filters) have been adopted for all European passenger cars, in order to comply with the PM (Particulate Matter) EU5 emission limits. Several studies , , , , , , demonstrated that DPFs are capable of physically capturing diesel particulates with extremely high filtration efficiencies, thus preventing their release into the atmosphere.
Starting with 2007 model years, diesel trucks are “blessed” with a diesel particulate filter (DPF). DPFs grab soot from your exhaust before it blows out into the environment. It’s a wall-flow filter usually made of cordierite, silicon carbide, or a ceramic monolith.

Diesel engines produce large amounts of particulate matter, or soot, as a by-product of coustion, and require diesel particulate filters (DPFs) as part of the exhaust system. IV, HS, KA27-28, KW, PA20-49, PA60-78, PH17-26, PH30-44, ZE, BT, IM, TR21-25, AB

2015/7/3· Silicon carbide was chosen instead of cordierite because in a passively regenerating system, its higher thermal mass and thermal conductivity can provide a greater measure of safety against performance degradation or failure due to interactions between the].

Brussels, Belgium, March 2014 As a leading global manufacturer of original equipment DPF units, Tenneco has realigned its Aftermarket range under the Walker Evolution name. The company offers Walker “EVO S” silicon carbide filters matching the technology used by many vehicle manufacturers and in addition new “EVO C” units, featuring advanced cordierite technology that is appropriate
How Can We Control Diesel Emissions? Diesel emissions are controlled either at their very source, through engine design and modifiions, or by exhaust gas aftertreatment. The two approaches are in fact complementary and are followed simultaneously in real life.
Cordierite (Mg2Al2O3SiO2) – low thermal expansion <0.5x10-6/K – low thermal conductivity 0.5 Wm/K – softening range of 1260 - 1360 C – Mass = 0.50kg/l Silicon Carbide (SiC) – Expansion of SiC is 3.54x10-6/K – high coefficient of thermal conductivity 1030
However the lower melting point of cordierite (it is heat resistant to 1430 degrees centigrade versus SIC’s 2200) can mean there is a risk of the component melting during DPF regeneration. Cordierite is also more susceptible to thermal crack due to sudden changes in …
Cordierite DPFs look very similar to alytic Converters and are mostly used in additive systems in conjunction with Diesel Oxidisation alysts. They are often used in aftermarket products and can be found in our standard DPF range. Silicon Carbide They
