What does GPF mean in cars?
1 Answers
GPF stands for 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. Through ECU control, the captured particles are oxidized and burned, achieving the purpose of regeneration. More related information is as follows: 1. When the warning light comes on, it indicates that active regeneration during driving can no longer effectively remove the deposited particles in the GPF, and it needs to be cleaned or replaced promptly. Driving at high speeds can help the GPF process the deposited particles on its own. 2. Generally, gasoline engines do not require a particulate filter. However, since direct-injection gasoline engines also have particulate emission issues, gasoline engines have started using particulate filters to comply with Euro 6 emission regulations. 3. 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 active regeneration function is triggered. (Regeneration involves burning off the accumulated particles in the GPF to restore its function. This regeneration process is primarily controlled automatically by the vehicle's ECU, which increases exhaust gas temperature and oxygen content to meet the conditions for triggering and maintaining regeneration. Typically, this process lasts about twenty minutes, during which the dashboard will indicate that regeneration is in progress and the vehicle should continue to be driven.)
