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...
