Accuracy of exhaust emission factor measurements on chassis dynamometer.

Résumé

In order to improve the accuracy, reliability and representativeness of emission factors, 10 European laboratories worked together to study the influence of 20 parameters on the measurement of light vehicle emission factors on chassis dynamometer of 4 main categories: driving patterns, vehicle related parameters, vehicle sampling and laboratory related parameters. The results are based i) on literature synthesis, ii) on about 2700 specific tests with 183 vehicles and iii) on the reprocessing of more than 900 tests. These tests concern the regulated atmospheric pollutants and pre-Euro to Euro 4 vehicles. Of the 20 parameters analyzed, 7 seemed to have no effect, 7 were qualitatively influential, and 6 were highly influential: gearshift strategy, vehicle mileage, ambient temperature, humidity, dilution ratio and driving cycle. The first 4 of the 6 were able to have correction factors developed for them. The results allow the design of recommendations or guidelines for the emission factor measurement method.
