Abstract

At present, the standard Euro is emission standard valid within the framework of the European Union. This emission standard relates to road transport specifically, and the actual issue of the standard is Euro 6, which is established to eliminate most undesirable air pollutants. A total of 10 passenger cars equipped with diesel engines and gasoline engines were tested within the present study, whereby these engines officially fulfilled the emission standards Euro 4 ÷ 6. Considering all data obtained using the PEMS measurement system, the diesel engine emissions are several times higher than the NEDC emissions. However, the real NOX emissions of the gasoline engines exceed the NEDC emission values only in a reduced form and are well below valid emission standards. Additionally, the results obtained by the NEDC cycle are in contradiction with the findings achieved in the case of two alternative driving cycles, namely, in the case of the Common Artemis Driving Cycles (CADC) and the Worldwide harmonized Light vehicles Test Cycles (WLTC). These results demonstrate the importance of implementing new kinds of driving cycles for performing generally binding motorcar emission tests. In this way, it is also possible to solve emission problems within urban destinations to improve air quality and public health.
