With the increasingly strict emission standards for automobiles, non-exhaust particulate matter emission, especially brake wear particulate matter emission, is becoming more prominent. In order to investigate the emission characteristics of brake wear particles under different test cycles, in this study a set of drum brakes is selected to conduct research on PM2.5 and PN10 emission under different test cycles(WLTP-Brake、WLTP、C-WTVC and CHTC-LT cycle) on a brake emission testing system modified based on a brake inertia table. The research results show that there are significant differences in the average initial/final braking temperature of the brake drum under different test cycles, and the highest final braking temperature generally occurs in the braking event corresponding to the maximum initial braking speed in the cycle. The PM2.5 emission factor of the test brake drum under WLTP-Brake cycle is 1.67 mg/km/wheel (the Euro 7 vehicle emission limit of 7 mg/km/vehicle), so the particulate matter emission control of the brake drum, like the brake disc, needs our attention. In addition, the initial braking speed of each cycle has a significantly greater impact on brake particle emission than braking characteristic parameters such as average braking deceleration. This study has practical reference value for the development and testing of low emission brakes for brake enterprises.
