Gasoline Direct Injection (GDI) concepts are the key technology of gasoline engine development to reduce CO2 emissions while improving torque and power output [1]. However the drawback of GDI engines are increased particle number (PN) emissions compared to conventional Port Fuel Injection (PFI) engines [2] [3] [4]. For compression ignition engines (Diesel engines) a PN limit of 6E11 #/km was already introduced with the enforcement of Euro 5b (09/2011). The Euro 6b legislation also covers a PN limit for GDI engines effective from 09/2014. During the first three years of the introduction the manufacturer is permitted to apply a higher PN limit of 6E12 #/km. Finally a stricter limit of 6E11 #/km will become effective for all passenger cars and light duty trucks from 09/2017 (Euro 6c).
