Development and Testing of a Zero Emission Drive Unit for Battery Electric Vehicles
AI summary Read the abstract
Researchers developed and tested a zero-emission electric vehicle designed to capture both brake and tire particulate emissions at the source. The vehicle incorporated collection systems for non-exhaust emissions, addressing a category of air pollution that standard electric vehicles do not eliminate.
Particulate matter emissions impair people’s health. So far there have only been studies on specific emissions from brakes and tires of vehicles with combustion engine, which are mainly determined on test benches. Environmental influences or effects in real drive operation of battery electric vehicles are not yet fully known. This paper describes the development of a zero-emission electric vehicle in which the brake particle emissions and the tire particle emissions are collected and removed from the environment. The first part describes the problem of non-exhaust vehicle emissions. These are negative health impacts through fine dust and environmental pollution by microplastic. In the second part the development process of a vehicle with the so called Zero Emission Drive Unit (ZEDU) is described. It shows the development of a demonstrator vehicle with highly reduced particle emissions due to a newly developed brake unit and a newly developed integrated tire emission extraction unit. The vehicle demonstrator was tested on a chassis dynamometer as well as on a test track. First results indicate that the tires emit the highest particle concentrations during the accelerating process. The brake emissions in the presented demonstrator are reduced to zero. The particle measurements show that the extracted tire emissions are reduced by over 90 % due to the used filter system.

Non-Exhaust Particle Emissions – Gaps and Research Needs
AI summary Read the abstract
Researchers review the regulatory and measurement gaps in non-exhaust vehicle emissions — tire and brake wear particles — noting that electric vehicles' greater weight increases these emissions by 7–17% compared to combustion vehicles, and that Europe's Euro 7 framework is just beginning to establish brake emission limits while tire abrasion standards remain unmeasured and unregulated.
Design of an Instrumented Electric Vehicle for Tire and Road Wear Particle (TRWP) Sampling: a Focus on Representativeness
AI summary Read the abstract
Scientists built a specially equipped electric car to accurately measure tiny particles that come from tires wearing down on roads, not just car exhaust. As cars produce less tailpipe pollution, this tire dust is becoming a bigger source of air pollution and microplastics, so better measurement tools help researchers understand what we're actually breathing in.
Comparison of Methods for Sampling Particulate Emissions from Tires under Different Test Environments
AI summary Read the abstract
Researchers compared different methods for sampling tire wear particle emissions under various test conditions, finding significant methodological differences that affect measurement outcomes and highlighting the need for standardized approaches as non-exhaust emissions become an increasing share of total vehicle pollution.

AI summary Read the abstract
Researchers projected airborne tyre wear particle (TWP) emissions in the United States over 2024-2044 using the Motor Vehicle Emission Simulator (MOVES), finding that the transition to electric vehicles will alter TWP emission profiles given differences in vehicle mass and regenerative braking behavior.
Investigations of airborne tire and brake wear particles using a novel vehicle design
AI summary Read the abstract
Tiny particles from tire and brake wear, not just tailpipe exhaust, are a growing air pollution concern, especially as electric cars reduce exhaust emissions but still create this "non-exhaust" pollution. Researchers tested a specially designed car with a filtering system and an enclosed brake system, finding it cut particle emissions by about 30% compared to conventional brakes, with the most particles released during hard acceleration and braking. This matters because these particles can be inhaled and may contribute to health problems linked to air pollution, so redesigning vehicle parts to capture them before they become airborne could be a meaningful way
