Abstract

Abstract The article presents and discusses the research results on the impact of RDE test dynamic parameters on the emission of selected exhaust components. The measurements were carried out in compliance with the latest legislative procedures applicable to passenger cars. Two passenger cars with similar curb weight, equipped with gasoline engine, were selected for the tests in real traffic conditions. All tests were performed on the same research route, which includes urban, rural and motorway conditions. The obtained results were analyzed of RDE procedure’s requirements and the Euro 6c toxicity standard. Then the values of dynamic parameters of both tests were compared (the vehicle velocity and acceleration product, relative positive acceleration and 95th percentile of V·a+). Their effect on the obtained emission results was determined. As a summary, the correlations between the on-road exhaust emission and dynamic parameters were defined.
