Embodiment Construction

[0018] Below, according to the limitation of the national standard HBC32-2004 on the working capacity test procedure of the activated carbon canister, in conjunction with the accompanying drawings, the embodiments of the present invention will be further described.

[0019] Such as figure 1 As shown, the test steps are as follows:

[0020] 1. At the beginning of the test, the electronic balance A weighs the activated carbon tank and sends it to the computer measurement and control system for recording;

[0021] 2. Adsorption test: Use a mixture of 50% volume butane and 50% volume nitrogen to conduct an adsorption test on the activated carbon tank. At this time, control solenoid valve A and solenoid valve D to open, solenoid valve B and solenoid valve C to close, and conduct the adsorption test. The pipeline is connected, and the mixed gas is adsorbed on the activated carbon tank and enters the atmosphere through the adsorption flow regulating valve, adsorption flow sensor, so...

Description

technical field [0001] The invention belongs to a testing and measuring device for gasoline vehicles for environmental protection, and relates to a working capacity testing device for activated carbon tanks used in vehicles. Background technique [0002] A variety of harmful emissions from automobiles are an important source of air pollution. With the improvement of people's awareness of environmental protection, in order to control the production of fuel evaporative pollutants, foreign countries have begun to install fuel evaporative pollutant control on gasoline vehicles since the 1970s. device. In 1995, my country also promulgated relevant laws and regulations to control fuel evaporative emissions. Although there are many kinds of control devices, the pollutant control device with the fuel vapor storage device activated carbon tank as the core is currently the main form used at home and abroad. With the increasingly stringent evaporative emission regulations, it is impe...
