Cordierite Diesel Particulate Filter

Cordierite Diesel Particulate Filter is a key component in modern diesel engines designed to reduce particulate emissions, specifically soot and other harmful particulate matter that can be harmful to both the environment and human health. It is primarily used in diesel-powered vehicles, including trucks, buses, and passenger cars, as well as in industrial machinery and off-road vehicles, to comply with stringent emission regulations. Cordierite DPFs are widely favored in the automotive industry due to their excellent thermal stability, high filtration efficiency, and long-term durability.

DPF Installation

A DPF is installed between an engine and a muffler to remove suspended particulate matter (SPM) from diesel engine exhaust gas.

The working principle of the particulate trap: By alternately blocking both ends of the pores of the honeycomb porous ceramic, the ceramic wall is used to filter and remove PM.
