盘式制动器:空气污染

盘式制动器 造成的 空气污染 占标准汽车总排放量的20%,而许多人从未认为盘式制动器是空气污染源。

"Vehicle tailpipe emissions are going down, but the emissions from disc brakes will remain to some extent, even if you drive an electric car," Weber said. "Therefore, this kind of process will continue to play out in the future and will be an important consideration when we look at the health effects of particulate matter." (Phys.org)
