Abstract

A test device for detecting pollutant emission from vehicle comprises a test chamber (1), a first air inlet pipe (5), a first blower (2), a heat exchanger (3), a pressure adjuster (4), and an air outlet pipe (6). The test chamber (1) is provided with an air intake (7) and an air vent (8). The first air inlet pipe (5), provided with a first air inlet valve (9), is connected to the air intake (7). The first blower (2) is connected to the first air inlet pipe (5). The heat exchanger (3) is located in the test chamber (1) which is connected to the pressure adjuster (4). The air outlet pipe (6), provided with an air outlet valve (10), is connected to the air vent (8).

Description

technical field [0001] The invention relates to test equipment, in particular to a vehicle emission test device. Background technique [0002] At present, after the vehicle is manufactured, it is usually necessary to conduct further vehicle pollutant emission tests on the vehicle. The vehicle pollutant emission test usually includes the emission test of the evaporative pollutants of the test vehicle and the emission test of the air pollutants in the test vehicle. Among them, the emission test of vehicle evaporative pollutants has higher requirements on the temperature, pressure, background concentration and sealing performance in the test device; while the emission test of air pollutants in the vehicle has strict requirements on the temperature, humidity, wind speed and background concentration etc. have higher requirements. [0003] In the prior art, two independent devices are usually used to conduct the emission test of vehicle evaporative pollutants and the emission te...
