AbstractMeasuring particle number (PN) in tailpipe have been considered to be a useful tool to detecting failures with DPFs. This methodology has already been adopted in periodic technical inspection (PTI) process in several European countries. In this study, correlation between the test with chassis dynamo and tailpipe PN has been obtained to evaluate the validity of this methodology. In addition to that, tailpipe PN were measured in Japanese PTI stations.
