ABSTRACT:
There is provided an emission testing system which maintains system integrity and which can be manufactured at less cost than current standard emission testing systems. The system includes a sampling unit for collecting emissions from a vehicle and diluting the collected emissions with background ambient air as required and means for drawing a proportional test sample from the bulk air/emission mixture. The analyzer is a single unit which includes a reaction cell for chemiluminescence reactions and a combustion cell for flame ionization analysis. In addition the system includes a common sample conditioning for the test sample prior to splitting the test sample for chemiluminescence and flame ionization analysis.
