AB The vehicle emissions tests, which are performed using the Portable Emissions Measurement Systems (PEMS), indicate that the diesel cars produce several times more NOx emissions on the road than during certification realised according to the methodology New European Driving Cycle (NEDC). This fact initiated the infamous "dieselgate" affair. It is a well-known reality that the current emission limits are very strict and therefore a serious problem arises for the motor car producers to meet the demanding emission requirements. The main task of the presented research work was testing of 10 passenger cars with regard to true values of their exhaust gas emissions. These cars were equipped with the diesel engines and gasoline engines that officially meet the Euro 4-6 standards. Based on the measured results it was found that the real NOx emissions of the diesel engines significantly exceed the values measured by NEDC. The results obtained using the NEDC cycle also contradict the findings from two alternative driving cycles: CADC (Common Artemis Driving Cycle; Artemis - Assessment and Reliability of Transport Emission Models and Inventory Systems) and WLTC (Worldwide harmonized Light vehicles Test Cycle).
