Gasoline particulate filters (GPF) are used to remove particulate matter from the exhaust gas of gasoline direct injection (GDI) engines. Due to regulations to reduce carbon dioxide emissions, GDI vehicles are becoming more and more popular, and the most cutting-edge is legislation like Euro 6.2. However, GDI engines have higher particulate emissions than port fuel injection gasoline engines.

Gasoline particulate filters (GPF) are used to remove particulate matter from the exhaust gas of gasoline direct injection (GDI) engines. Due to regulations to reduce carbon dioxide emissions, GDI vehicles are becoming more and more popular, and the most cutting-edge is legislation like Euro 6.2. However, GDI engines have higher particulate emissions than port fuel injection gasoline engines. GPF captures particulate matter to control particulate matter emissions, and ultimately makes the cars we drive cleaner for the environment. It includes a honeycomb filter structure made of synthetic ceramic material. When the exhaust gas passes through, the filter traps soot particles. When the exhaust gas temperature is high, the soot is burned and the filter is regenerated. In most cases, the filter operates in a passive manner under a constant capture and regeneration cycle. The DPF will capture soot, and then need a special engine mode to regenerate. The GPF filter is very efficient and can capture more than 90% of the airborne particles that would otherwise be released into the atmosphere.
