Real-World emissions of Euro VI Heavy-Duty Vehicles
article
The Euro VI Step E emission standard for heavy-duty vehicles (HDVs) is the first step to introduce cold-start emissions analysis as part of the on-road In-Service Conformity (ISC) requirements. The intention is to reflect the engine cold-start requirements foreseen in the World Harmonized Transient Cycle (WHTC) type approval cycle. In addition, a limit is introduced for solid particle number (PN) to be measured with Portable Emissions Measurement Systems (PEMS). The new regulatory step continues using the Moving Averaging Window (MAW) data post-processing prescribed by the Euro VI regulation, with additions to consider the cold-start emissions.
