Study of NOx emission behaviour of a Jeep Grand Cherokee Euro 5a diesel
report
In an emission study reported by the Netherlands Vehicle Authority (RDW) in July
2017 [RDW 2017], the first exploratory emission tests for the Jeep Grand Cherokee
Euro 5a were carried out. The test results concerning the measured NOx emissions
gave rise to further research. In 2018, the Netherlands Vehicle Authority (RDW) commissioned TNO to carry out an emission study of the Jeep Grand Cherokee Euro 5a diesel. The goal of the study was to map the Jeep Grand Cherokee emission behaviour, measured with 2 different engine calibrations (C1 & C2). To this end, several partial objectives were formulated and emission measurements were carried out on a test track of the RDW, on a dynamometer and on public roads. When taken together, the results of these measurements provide a good overview of the emission behaviour of the tested vehicle and the differences in emissions before and after the update of the engine calibration software. The partial conclusions based on the performed measurements have been included
below.
