CITA Webinar: “New Approaches to Vehicle Emissions Inspections – pt 2”

30 June, 2021 @ 2:00 pm - 4:00 pm

Our webinar entitled: “New Approaches to Vehicle Emissions Inspections – pt 2” will take place Wednesday, 30 June 2021 at 02:00 pm CEST on zoom platform.

In this second webinar on the 3DATX sponsored PTI Trial, the vehicle emissions database is expanded to over 160 vehicles, a four-fold increase since the first webinar in February 2021.

This update will include:

  • Proposed enhanced PTI test protocol for gaseous and particulate emissions from gasoline and diesel fueled vehicles, where emissions tests are completed in 70% less time compared to the protocol presented in the first webinar.
  • Preliminary threshold for nitrogen oxides (NOx as NO + NO2) emissions to identify malfunctioning or tampered emissions aftertreatment devices. Three variants of emissions thresholds are proposed – normal idle, stationary high RPM, and short driving acceleration – to satisfy the compliance targets and restrictions per country.
  • Comparison of carbon monoxide (CO) and particle number (PN) from the enhanced PTI protocol to the current PTI based CO and smoke opacity, respectively
