The influence of the driving style on the CO2 emissions from a passenger car

With the invention of specialized, portable research equipment, construction of which enabled road tests of vehicles, it has become possible to verify benefits ensuing from application of eco-driving rules outside the laboratory – the test stand measurements. Test of the vehicles’ operation in terms of ecology are essential especially in case of toxicity of exhaust gases in dynamic, transient conditions of engine operation. Despite the attempt to reflect those conditions in dynamic research tests, it is not possible for fully reconstruct real conditions of operation of vehicles of different homologation categories. Due to this fact in recent years, the biggest research potential in automotive industry has been focused right on the road tests of vehicles in real traffic conditions. The article presents the results of measurements of exhaust emissions of passenger car in real traffic conditions. The aim of this study was to initial verification how the driving style influences on the carbon dioxide emissions from vehicle engine and fuel consumption. The determinants were the measurements of the concentration of CO2 emitted to the atmosphere from the power unit of the tested vehicle. In the measurements, a portable exhaust emission analyser was used.
