Tracing Method for Electronic Snapshot System of Black Smoke Vehicle

The calibration device and the method of source tracing for the electronic snapshot system of black smoke vehicle are researched in this paper. Through a large number of tests on the environmental factors, the appropriate calibration conditions are determined. The accurate and reliable tracing of the electronic snapshot system of black smoke vehicle can be realized through this research, which makes up for the technical blank in this field. It also provides technical support for the environmental protection department to monitoring vehicle exhaust black smoke situation, which plays important role for monitoring and screening black smoke vehicle.
