Abstract

The invention provides an automatic carbon powder effective volume testing system. The automatic carbon powder effective volume testing device comprises a rack and testing equipment installed on the rack, a branch carbon powder storing and weighing device is arranged under a discharging port of a main carbon powder storing and weighing device, a vibration feeding device is arranged under a discharging port of the branch carbon powder storing and weighing device, and a carbon powder effective volume testing device is arranged at the discharging end of the vibration feeding device. The main carbon powder storing and weighing device, the branch carbon powder storing and weighing device, the carbon powder effective volume testing device and the vibration feeding device are further connected with a main control device. The automatic carbon powder effective volume testing system saves manpower consumption, improves the accuracy of a test result, and is beneficial to improving the detection efficiency of the effective volume of carbon powder.

Description

technical field [0001] The invention belongs to the technical field of automobile detection, and in particular relates to an automatic detection system for the effective volume of carbon powder. Background technique [0002] Compared with the fifth stage, the national light-duty vehicle six-stage emission standard has tightened the requirements for Type IV evaporative emission limits, and at the same time increased the requirements for Type VII refueling emission tests. In response to the more stringent evaporative emission regulations in the sixth stage and the newly added refueling emission regulations, the main engine factory redesigned the effective volume of the carbon tank, the proportion of carbon powder, and the proportion of the shell, and tested the effective volume of carbon powder in the carbon tank It is also constantly increasing, and the measurement result of the effective volume of carbon powder directly affects the accuracy of the final result of the subsequ...
