摘要：
Subject of the invention is an exhaust gas purification system for a gasoline engine, comprising in consecutive order the following devices:
a first three-way-catalyst (TWC1), a gasoline particulate filter (GPF) and a second three-way-catalyst (TWC2), wherein the wash coat load (WCL) of the GPF is greater than the WCL of the TWC2, wherein the WCL is determined in g/l of the volume of the device. The invention also relates to methods in which the system is used and uses of the system.
