- Abstract
Recent research shows that pollutant emissions and fuel consumption of diesel vehicles in the real world often exceed the levels achieved in the homologation processes. By means of a portable emissions measurement system (PEMS), nitrogen oxides (NOx) were measured. These tests show as NOx emissions exceed the limit imposed by the Euro 6 norm. Thus, in order to complete the current homologation cycle (WLTC), the real driving emissions regulation (RDE) has been introduced, starting on September 1, 2017. This paper shows an analysis of NOx emissions on-board measurements in a Euro 6 diesel vehicle during an actual driving test by using a portable emissions measurement system (PEMS). The characteristics of this test route follow the requirements imposed by the RDE regulation. The analysis of emission results shows that the greatest amount of NOx per kilometer is emitted during the urban part of the test. Generally, in sections at low speeds with abrupt accelerations and decelerations. On the other hand, in sections with smoother accelerations and with periods maintained at intermediate speeds, this parameter is much lower. It can be 5 times lower than in the case of the sections with the highest NOx rates
