Gasoline Particulate Filter (GPF)
-Due to many advantages, such as increased output, reduced engine size, improved fuel economy, and emissions regulation in gasoline engine cars, the ratio of fuel injection to indirect injection (MPI) to direct injection (GDI) is increasing. The engine produces a large number of nano-sized particulate matter due to the low fuel uniformity in the cold start section and the high speed, high load operating range, which can be removed by using a gasoline filter (GPF) with a rare catalyst.
-Heesung Catalyst GPF products can be classified into three types according to the location of use, and they meet all the characteristics required for each product.
CC Only (Close Couple Only)
ㆍ The role of existing three-way catalyst (TWC) and GPF to remove PN are composed of one catalyst
CC-2 (Close Couple – 2)
ㆍ Constructed as one converter by placing three-way catalyst at CC-1 position and GPF at CC-2 position
UCC
ㆍ Two-way catalyst in CC position and GPF in UCC position, consisting of two converters.PN removal system that is easy to apply to existing three-way catalyst system
