The introduction of new exhaust emissions norms for motor vehicles forces manufacturers to rely on new technologies of exhaust gas aftertreatment and emission reduction. Past studies by the authors have demonstrated a significant emission of nanoparticles from gasoline engines with direct fuel injection, especially dangerous for human health and life. The latest solution is a particulate filter designed for spark ignition engines, introduced in parallel with a norm limiting their number emission. The research conducted within the article concerned testing its effectiveness by measuring the vehicle equipped with and without the filter in real driving conditions. The drive cycle was made in accordance with the requirements of the RDE (Real Driving Emission) standard using PEMS (Portable Emissions Measurement System) equipment. The values of harmful gaseous components and solid particles were measured in terms of mass and number. The emission results comparison indicated a significant efficiency of the filter in terms of particle weight and number reduction. The dimensional distribution of particle diameters has also been analyzed, which has also changed as a result of the filter. The authors believe that the filter's efficiency is the result of much higher temperatures of exhaust gases than in the case of diesel engines, which causes the incineration.
