Embodiment Construction

[0107] The present invention will be further described below in conjunction with the accompanying drawings.

[0108] The method for testing the emission of all components of vehicle exhaust gas based on the principle of time alignment provided by the present invention comprises the following steps:

[0109] Step 1. Build as figure 2 The vehicle emission test platform for all components of motor vehicle exhaust pollutants shown;

[0110] The test platform includes two parts: the pollutant vehicle emission test system and the control host 8 .

[0111] 1. Vehicle-mounted emission test system for all components of pollutants

[0112] The vehicle-mounted emission test system for all components of pollutants includes a motor vehicle that is arranged in parallel and communicated with the exhaust pipe 7 of the motor vehicle through the heating sampling line 6 (using the heating sampling line can avoid the condensation of hydrocarbons and water vapor in the sampling pipe). The on-b...

Abstract

In order to achieve the full-component testing of pollutants of a motor vehicle, the present invention provides a motor vehicle tail gas pollutant full-component discharge testing method. According tothe present invention, a motor vehicle tail gas pollutant full-component vehicle-mounted discharge testing platform is established, carrying out data-time aligning based on the platform, and calculating the transient discharge results of various pollutants so as to achieve the full-component testing of the pollutants of the motor vehicle.

Description

technical field [0001] The invention relates to the technical field of motor vehicle pollutant emission testing, and relates to a method for testing the emission of all components of motor vehicle exhaust pollutants. Background technique [0002] With the increase of the number of motor vehicles in recent years, motor vehicle emissions have gradually become the main source of air pollution. Especially in some big cities and eastern densely populated areas, the contribution of mobile sources to the concentration of fine particulate matter is as high as 20%-40%. At the same time, since motor vehicles mostly drive in densely populated areas, exhaust emissions directly threaten human health. In order to better control the emission of motor vehicles, a lot of testing and research work on exhaust components is needed. Traditionally, motor vehicles (or engines) have been primarily simulated on laboratory benches. Although the laboratory bench test is easy to control the test con...
