Gasoline particulate trap: GPF (GASOLINE PARTICULATE FILTER) is a ceramic filter installed in the gasoline engine emission system. It is basically the same as the DPF filtration mechanism of diesel engines. It can capture particulate emissions before they enter the atmosphere.
Use environment:
The purpose of the EGR sensor is to make the vehicle comply with the exhaust emission standards of countries around the world. The EGR monitoring temperature sensor is installed downstream of the EGR valve to detect the temperature change of the recirculated gas (part of the exhaust gas from the exhaust manifold to the intake manifold) downstream of the EGR valve to monitor the EGR valve’s temperature. Working conditions.
The National Six emission regulations put forward stricter requirements for the emission of particulate matter from gasoline vehicles. Compared with the National Five regulations, the particulate matter (PM) limit has dropped by 33%, and the new limit requirement for the number of particulate matter (PN) . To reduce the particulate emissions of gasoline engines, in response to this problem, major automakers have chosen to install a gasoline vehicle particulate trap (GPF) in order to respond to the new national VI standard.
