Influence of Driving Cycles on Emission Parameters of Vehicles

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