COMPARISON AND OPTIMIZATION OF EXHAUST EMISSION TEST PROCEDURES

Distribution functions of repetitive exhaust measurement results on the same vehicles and of single measurement results on many vehicles from the assembly line are investigated. The correlation between mass emission components is also analyzed. The probabilities for passing or failing certification tests are calculated using a Monte Carlo-method under consideration of the standard deviations of test data. From the results of these statistical and experimental investigations, proposals for the improvement of certification- and assembly line tests procedures for the USA and Europe are deduced. /GMRL/
