BCA-8000 is a CVS dilution air purifying facility developed for ultralow concentration exhaust gas measurement (Apply to SULEV regulation).
Development of high-efficiency engines and improvement of aftertreatment technologies give rise to the phenomenon of lower concentrations of harmful components emitted from vehicles than the environmental air.
BCA-8000 provides solution to the problem of emission flow rate which is a large factor of error in the SULEV measurement.
