Abstract: Particulate filters are used to remove particulate matter such as soot and ash in the emissions control systems of vehicles, including gasoline direct injection (GDI) engines. Methods are provided to predict the long-term performance and durability of emissions control systems having particulate filters. The methods account for factors such as thermal aging, soot accumulation and regeneration, and ash loading.

Abstract: Gasoline Direct Injection (GDI) engines require gasoline particulate filters (GPFs) as a key component of the emissions control system to reduce particulate emissions. GPFs are known to have poor initial performance, with performance increasing after the filter develops a cake. This poor initial performance make it impossible to accurately assess vehicle emissions performance at the mileage requirements for vehicle certification. Compositions and methods are disclosed to improve filtration efficiency in a fresh or low mileage GPF.
