At source brake dust collection system

Given the progress made to limit the exhaust particles emission from vehicles, particles emitted by brakes during braking are becoming a rising problem. To tackle this, Tallano has developed a brake particles collection system named TAMIC. TAMIC was de-signed to trap at least 80% of brake particles directly at the pad-disc interface without altering braking efficiency. It is composed of a brake calliper especially designed for the integration of grooved pads and of an aspiration system where brake particles are trapped. The aspiration system relies on pipes connected to a turbine equipped with a high efficiency filter. The whole system is driven by an embedded electric brushless motor. Several types of characterizations, like PIV (Particles Image Velocimetry) and simulations have been performed. Mass and number collection efficiencies have been assessed on brake rigs. A mass efficiency above 85% and a number efficiency up to 90% have been achieved. Performances on vehicle and impact on its behaviour have also been verified on test track and in real driving conditions with same level of collection performances. •Design of an at source brake dust collection system for automotive.•System particulate matter reduction efficiency evaluation regarding mass and number on bench test.•System particulate matter reduction efficiency evaluation regarding mass on vehicle testing.
