ABSTRACT:
A non-contact, extractive sampling system and method is provided for measuring the exhaust gas composition and fine particle composition of exhaust emissions of various types of vehicles under actual operating conditions. A portion (or sample) of an exhaust plume of a vehicle is pulled or extracted through an extraction sampling tube, via a vacuum pump, to a remote trace gas detection system where the concentration of one or more constituents present in the sample of exhaust plume may be measured. In this regard, the invention enables vehicle emissions measurements to be made at a location remote from roadway, rather than using known, “cross-path” remote emissions sensing systems.
