Background
There are three main types of exhaust particulates for diesel engines: carbon particles (Soot), particles of surface-adsorbed organic Soluble Substances (SOF), and sulfate particles. Diesel exhaust particles are mostly composed of Soot and SOF particles.
A Diesel Particulate Filter (DPF) is a Particulate Filter installed in an exhaust line of a Diesel engine, and captures Particulate matter in exhaust gas to achieve the purpose of purifying the exhaust gas. When diesel engine exhaust flows through the DPF, particulate matters in the exhaust are trapped by the DPF through processes of interception, diffusion, gravity sedimentation, inertial collision and the like, the trapping efficiency is mainly influenced by factors such as filter material structure, particle size, exhaust temperature, exhaust flow rate and the like, and the filtering efficiency of the conventional wall-flow honeycomb ceramic particulate trap on the particulate matters can be up to more than 90%.
