Abstract
The Euro 7 emission standards for light-duty vehicles released at the end of 2022 have for the first time restricted the emission of non exhaust particulate matter from vehicles, which has attracted widespread attention from brake and tire manufacturers and vehicle manufacturers. Prior to this, there were few reports on the testing methods for brake wear particulate matter emissions in China, and most of them focused on studying the emission characteristics and composition of brake wear particulate matter emissions. This article reviews the testing methods for particulate matter emissions from light-duty vehicle braking wear at home and abroad, including methods based on inertia dyno bench, operating loss sealed chamber, actual road and pin-on-disc tribometer.
