What does GPF mean?

[LaElaina]

Automotive GPF refers to the Gasoline Particulate Filter, which is a ceramic filter installed in the exhaust system of gasoline engines to capture particulate emissions before they enter the atmosphere. The placement of GPF in the exhaust system of gasoline engines mainly includes the following three forms: 1. Close-coupled arrangement: Integrated with the TWC and installed close to the exhaust manifold, known as the close-coupled arrangement. 2. Rear-mounted arrangement: Installed directly downstream of the TWC, known as the rear-mounted arrangement. 3. Quadruple catalyst: A ternary catalyst is coated on the substrate of the GPF, forming a quadruple catalyst.
