Vehicles will comply with upcoming Euro 6 RDE limits with particle number emissions measured to a 10nm size threshold
Example measurements of particle size & number (on the colour scale) over a transient test
- PaREGEn baseline vehicle measurements made over the NEDC, WLTP (high and low), and RDE (on-road and on-dyno) with AIRMODUS and EEPS instruments
- Over the wide range of tests the baseline vehicles were well below the relevant legislative PN levels
- The relationship between the PN23 and PN⑩ measurements is consistent with the other measurements made within the DownToTen project
Emissions target values to be fulfilled by the demonstrator vehicles have been determined. A testing protocol based on NEDC, WLTP and NEDC has been adapted to the new systems developed and the additional equipment used. The RDE correlation between the real road tests and simulation on the chassis dynamometer has been achieved. Baseline test results from the JaguarLandRover and Daimler vehicles has been obtained. Test results from the demonstrators vehicles will be obtained in 2019. An impact assessment of the new technologies will be made thereafter.
