The Impact of the Driver’s Driving Style on the EXHAUST Emissions of a Passenger Car during a Real Road Cycle

The research was carried out using the Horiba OBS ONE GS12 portable emission measurement system (PEMS), installed on a Skoda Octavia III 1.4 TSI vehicle. The scope of research included performing a validation test in emission laboratory on a chassis dynamometer in order to check if the operation of the measuring system is correct and performing three real driving emission tests on public roads in Bielsko-Biala and the surrounding area. Each of tests was performed with a different driving dynamics to determine the effect of the driver's driving style on the vehicle's emissions in real road cycle. Each RDE test consisted of three parts (urban, rural and motorway). During the tests the program Horiba DMC was used. However, the obtained results were calculated using the DIAdem program. After the tests, exhaust gas emissions as a function of time and exhaust emissions dependent on driving dynamics were presented and analysed graphically. These diagrams illustrate the impact of driving dynamics on the exhaust emissions in a good way.
