Logo for BTAS, brake and tires analysis system, with large orange 'BTAS' letters and a gray description text.

With the trend in many automotive markets towards heavier vehicles with greater torque, non-tailpipe emissions are becoming a more prevalent source of emissions, in many cases dominating tailpipe pollution. Emissions Analytics’ BTAS© equipment allows for real-world measurement of emissions from tyres and brakes, compared to the atmospheric background (patent pending - UK Patent Application GB2210310.5).

BTAS is an integrated system for the real-time, on-road measurement of tyre and brake wear emissions separately from each other and from background concentrations. Measurements can be taken on every wheel of a vehicle, including the steering wheels. It is a combination of a physical sampling system, online measurements and offline testing and analysis. It also allows the collection of physical wear material for separate analysis.

Measurements

The following measurements are available separately for tyre and brake wear:

  • Integrated mass loss

  • Real-time particle mass and number concentration, plus size distribution

  • Background pollution concentrations

  • Volatile organic compounds off-gassed

  • Chemical speciation of the original tyre and brake components, and wear functional group compound classification.

We can test to these additional standards.

With these measurements, a ‘contamination factor’ is derived using chemical fingerprinting, which estimates the proportion of non-tyre material collected in the tyre sampling rig, and the equivalent proportion of non-brake material from the brake sampling rig.

Emissions Analytics independently sources and tests vehicles to support our clients market analysis and R&D. Measurements include fuel efficiency, carbon dioxide (CO2), carbon monoxide (CO), nitrogen oxides (NOx), nitrogen dioxide (NO2), particulate number (PN) and OBD data.

Over 2,000 European, US and South Korean market vehicles available.

Results are available via a cloud-based database and also via Excel upon request.
