What does GPF mean?

[AmirRose]

Automotive GPF refers to the Gasoline Particulate Filter, with relevant information as follows: 1. GPF: It is a ceramic filter installed in the exhaust system of gasoline engines, capable of capturing particulate emissions before they enter the atmosphere. 2. Wall-Flow Particulate Filter: The filtration mechanism of GPF is basically the same as that of diesel engine's DPF. Exhaust gases flow at a certain velocity through porous walls, a process known as "Wall-Flow." The wall-flow particulate filter consists of honeycomb-shaped ceramics with a certain pore density. By alternately blocking the honeycomb-shaped porous ceramic filter body, the exhaust flow is forced to pass through the channel walls, and particulate matter is captured and filtered through four methods: diffusion, interception, gravity, and inertia.
