Problems solved by technology

[0005] In the device of the above-mentioned patent, the control of the accelerator pedal can be realized by the cooperation of the screw and the nut, but the device is installed on the chassis dynamometer of the whole vehicle and cannot be directly used in the interior of the vehicle. The structure of the vehicle itself cannot be damaged, so the device cannot be directly used in the vehicle's working condition method emission test

Embodiment Construction

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] During the specific implementation: a method of emission test of automobile working condition method. During the test, the automobile is located in the test environment cabin and is in an overhead state. The test environment cabin provides temperature environment simulation; After testing the standard speed, stabilize the speed at the same speed and maintain it according to the test standard for a period of time, and then check whether the exhaust emission of the vehicle reaches the standard; its characteristic is that the throttle control device of the vehicle working condition method with the following structure is obtained in advance, and the device is used Installed on the test vehicle instead of manually stepping on the accelerator pedal to control;

[0028] The throttle control device for the emission test of the automobile working condition meth...

Abstract

The invention discloses an automobile driving mode emission testing method. During a test, an automobile is located in a testing environment chamber and in an aerial state, and the testing environment chamber provides temperature and environment simulation; then, according to a testing standard, an accelerator pedal of the automobile is stepped to accelerate wheels to the testing standard speed, the speed is maintained unchanged for a period of time according to the testing standard, and then the automobile exhaust gas emission is detected whether reaches the standard or not. The automobile driving mode emission testing method is characterized in that a mechanical structure throttle control device of the automobile driving mode emission test is obtained in advance, and the mechanical structure throttle control device is installed on the testing automobile to replace manual power to step the accelerator pedal to control. The automobile driving mode emission testing method has the advantages that in the driving mode emission test, the manual power can be replaced to achieve the accelerator stepping action, the stability of throttle control is guaranteed, the testing precision is improved, the integrity of the testing automobile can be guaranteed, meanwhile, the implementation is simple, and the operation is convenient, rapid, stable and reliable.

Description

technical field [0001] The invention relates to the technical field of automobile emission tests, in particular to an emission test method of an automobile working condition method. Background technique [0002] Before the automobile is produced and leaves the factory, it is necessary to carry out the emission test of the vehicle operating condition method to check whether the engine emission can meet the requirements when the vehicle is in different environments. During the emission test of the vehicle working condition method, the vehicle is located in the test environment chamber and is in an overhead state, and the test environment chamber provides different temperature environment simulations. Then it is necessary to depress the accelerator pedal of the vehicle to accelerate the wheels to a certain speed, then stabilize at a certain speed and maintain it for a certain period of time. [0003] In the prior art, the vehicle operating condition method emission test genera...
