Product Description

SiC DPF is a wall-flow honeycomb ceramic filter. Its channels are alternately plugged at opposite ends. Diesel exhaust flows into the inlet channels and is forced to penetrate the porous SiC wall. Soot and particulate matter (PM) are trapped on the porous substrate, while clean gas passes through to the outlet channels. Filtration efficiency can reach over 95%.

As soot accumulates, exhaust backpressure rises. Regeneration burns off trapped soot to restore filter capacity:

Passive Regeneration: NO₂ generated from upstream DOC oxidizes soot at relatively low temperature with catalytic coating.
Active Regeneration: Exhaust temperature is raised to 550–650°C. The soot reacts with oxygen and burns into CO₂.

Silicon carbide has much higher thermal conductivity than cordierite. It distributes heat evenly during regeneration, effectively avoiding thermal cracking and local overheating, which makes it ideal for heavy-duty diesel engines.
