Diesel particulate filter is also called DPF, is the key component of exhaust system of diesel engine vehicle or machine.it is a kind of wall-flow honeycomb ceramics, made of cordierite ceramics, with features of strong mechanical strength, high open porosity, high soften temperature, low thermal expansivity etc. Because of the above features, DPF is an idea component for diesel soot filter; it has an excellent performance in filtering the fine particulates in the diesel engine exhaust. Cordierite DPFs are the most used component in the diesel exhaust treatment.

Cordierite-based Diesel Particulate Filter is used for car catalytic converter can trap the particulate matter from diesel exhaust emissions, and have high filtering efficiency.
Main advantages of Diesel particulate filter (DPF) as below:
*High filtering efficiency.
*Low thermal expansion coefficient.
*High porosity.
*Good flow and uniform distribution.
*High temperature resistance.
*Anti acid erosion.
*High thermal shock resistance.
*Low backpressure.
*Suitable for all kinds of regeneration.
*High soot removal:>95%
