Particulate matter: this car kills emissions 🎥
FUTURE HWA AG uses its experience from the development of racing and other high-performance vehicles and complements the measures to avoid or reduce emissions in a concept vehicle.
HWA AG, the German Aerospace Center (DLR) and the Baden-Württemberg Ministry of Economics, Labor and Tourism presented the ZEDU-1 vehicle prototype in Stuttgart. ZEDU-1 stands for Zero Emission Drive Unit - Generation 1 and thus for the prospect of achieving virtually emission-free mobility with a vehicle.
Special extraction system for the accumulating fine dust
This electric car not only runs on an electric motor, but also enables a largely emission-free form of mobility thanks to internally encapsulated brakes and an extraction system for particulate matter and tire particles.
Today, it is brake and tire abrasion that accounts for between 60 and 70 percent of particulate matter generated from traffic. In the ZEDU-1, the electric motor, transmission and brakes form a single unit inside the vehicle. In other words, a real killer on wheels.
Change between electric and mechanical brake
The brake on this vehicle is a brake-by-wire multi-disc brake. The vehicle control system decides how to switch between electric and mechanical braking power based on the brake pedal force.
An adequately dimensioned mechanical brake is still necessary, primarily for safety reasons. At the same time, moving the brake inside the vehicle paves the way for a solution to reduce tire particle emissions.
A combination of aerodynamic effects while driving and active suction behind the wheel contact surface allow the particles to be collected while driving. A fan unit in the front of the vehicle then extracts the particles and conveys them through the filters integrated in the fan housing, so that only cleaned air is released from the vehicle into the ambient air.
