AVL – well known as a leading Engineering partner in Powertrain and Emission Measurement – has extended its portfolio following the market requirements pushed by EU7, which is regulating particle emissions of non-exhaust sources for the first time.
Why You Need the AVL Brake Emission Solution
In 2022 just 15 % of overall particle related emissions, originated from the tailpipe, were regulated. 85 % of the emissions were non-regulated and originated from sources such as brake wear, tire wear and road abrasion. To respond to this, a testing procedure for brake wear has been developed and implemented as a new Global Technical Regulation – the GTR-24. Based on this GTR particle mass and particle number (PM10, PM2.5 and CPC-based PN10 measurement) must be measured over a specified brake cycle on a brake component dyno.
Brake particle emissions will be part of EU7, starting with Passenger Cars / Light Commercial Vehicles in November 2026.
AVL is not only providing fully GTR compliant Brake Emission measurements and certification on component level but also the full package of engineering along the topic – providing performance and NVH testing up to optimization of recuperation strategies and homologation on full vehicle system level – as a One Stop Shop.
Together with partners such as Tribotecc and Treibacher AVL is quite active in the field of tribology optimization, brake disc coating and filter technologies.
Latest service package is the determination of vehicle specific Friction Brake Share Coefficients for the consideration of recuperation, utilizing our sophisticated Chassis Dynos, Driving Robots and Brake Torque Sensors.
Another big field is new brake technologies like Electromechanical Brakes – reducing particle emission by eliminating drag torque – or powertrain integrated lamella brakes without external emissions, combining „traditional“ AVL know how with deep brake system knowledge.
Similar approaches will be taken for heavy duty trucks – taking into acount the much wider range applications. A respective Brake Emission Dyno has just been put into operation.
