Aiming at serious problem of atmospheric PM 2. 5 pollution caused by motor vehicle,automobile exhaust PM 2. 5 emissions detection device is designed in order to detect automobile exhaust PM 2. 5 emissions. The characteristics of temperature,humidity and flow characteristics of automobile exhaust are considered,and exhaust collecting box is equipped with temperature control unit to improve detection accuracy. The PM 2. 5 emissions and temperature of box are tested when three kinds of vehicle at idle condition,and the test results show that the detection datas are stable,fast response and has small error.
