Abstract
Due to the strict regulation of vehicle exhaust emissions in the last two decades, about half of road traffic PM emissions are nowadays composed by non-exhaust particles from brake and tire wear and road dust resuspension. The brake wear emissions are poorly understood due to the large variety of chemical composition of brake pads, emission rates and a standardized method for their measurement. The ECO-BRAKE project aims at estimating emission rates for total PM and its components from conventional and innovative (Cu-free and Sb-free) brake pads, including Semi-metallic, low metallic, non-asbesto organic (NAO) and with different types of binder. Several bench tests were performed in a brake dynamometer simulating the emission rates in the AK Master driving cycle. Particle number and mass size distribution were monitored by means of ELPI+ (Dekati), OPS and Nanoscan (TSI). Size resolved components mass and emission rates were obtained by means of DLPI (Dekati) sampler and subsequent ICP-AES and ICP-MS analysis of particles collected on aluminum foils. Other monitored parameters were absorption CO, and CO2.
