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
Cordierite wall flow filters Silicon carbide wall flow filters. Metal fiber filters. Metal fiber flow-through filters Regeneration is a process in which trapped particles or particulate are burned from time to time.
Thus, to conform to the emission regulations, the use of DPF in HCV would increase drastically during the forecast period.Silicon carbide is the largest segment of the DPF market, by substrate, due to its large-scale use in passenger cars.

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
Silicon Carbide (SiC) DPF Cordierite DPF Others Market Segment by Appliions, can be divided into Light CV Truck Buses Off highway There are 15 Chapters to deeply display the global Diesel Particulate Filter (DPF) market. Chapter 1, to describe Diesel
Diesel Particulate Filters (DPF) utilize cordierite wall-flow monoliths to trap the soot produced by medium to heavy-duty engines in off-road, on-road and stationary appliions. The cylindrical filter element consists of many square parallel channels running in the axial direction, separated by thin porous walls, as shown below.
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.
DPF Monolithic structure honeycoof porous ceramic material with high mechanical and thermal strength (cordierite, carbide silicon, SiC) or metal sintered. The cells are closed either by a side and the other in order to filter continuous gas discharge retain
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].
