Tailpipe emissions: Light duty

Passenger car testing is where we began back in 2011. Since then, we have worked globally with manufacturers, technology specialists and government bodies to provide independent, robust, real-world analysis.

In addition to creating bespoke test cycles, we can replicate lab cycles such as WLTP on the road. Working with leading OEMs and emissions stakeholders, we also led the development of a cycle specifically for real-world comparison through CEN Workshop 90 – CWA 17379.

Measurements available both raw exhaust and post-aftertreatment:

  • Fuel economy (Mpg) and fuel consumption (L/100km)
  • Carbon monoxide (CO)
  • Carbon dioxide (CO2)
  • Nitric oxide (NO)
  • Nitrogen dioxide (NO2)
  • Oxides of nitrogen (NOx = NO + NO2)
  • Nitrous oxide (N2O)
  • Total hydrocarbons (THC)
  • Particle number (PN, lower size cut-off 23 nm)
  • Particle mass (PM)
  • Ammonia (NH3)
  • Formaldehyde (CH2O)
  • Speciated volatile organic compounds (VOCs)
  • Sulphur dioxide (SO2)
  • Methane (CH4)
