At Automotive Testing Expo Korea 2017, experts at the Jastec booth (5015) have spent much of their time in discussions about the new Sensors particle-counting PEMS based on condensation particle counter (CPC) technology. This advanced system took three years to develop and will be enable OEMs to test to the latest RDE standards.
In December 2016, the EU’s third RDE work package was approved. It provides guidelines for the measurement of particle numbers (PN) during real driving conditions and promulgates a conformity factor (CF) of 1.5 for PN as of September 1, 2017, for any new type approval; and on September 1, 2018 for all new vehicles. This CF includes an error margin of 0.5 (for cold starts only) and covers cold starts, regenerating events and hybrid vehicles. It requires the publication of CFs in the Certificate of Conformity of each vehicle.
These events/vehicles had previously been excluded from the requirement for PN, and this development represents a significant change in protocol.
Sensors’ new system consists of a proprietary laser-based CPC, two dilution stages and a catalytic stripper, to meet all legislative requirements of this work package.
Automotive Testing Expo Korea 2017 takes place until March 8 at the Korea International Exhibition Center in Seoul.
