What does GPF mean in cars?

[VanElliott]

GPF in cars refers to the Gasoline Particulate Filter, whose main function is to reduce particulate emissions. It is installed in the vehicle's exhaust system to capture particulate matter from the exhaust gases, effectively reducing particulate emissions. Controlled by the ECU, it oxidizes and burns the particulate matter collected in the filter to achieve regeneration. When the pressure reaches a specific value, meaning the particulate matter has accumulated to the point where it may affect normal vehicle performance, the GPF's regeneration function is triggered. Regeneration refers to burning off the accumulated particulate matter in the GPF to restore its functionality. This regeneration process is primarily automatically controlled by the vehicle's ECU, which increases exhaust gas temperature and oxygen content to meet the conditions for triggering and sustaining regeneration.
