Abstract

This invention provides a method and apparatus for testing exhaust emissions of vehicles having internal combustion engines. The apparatus of the present invention comprises a test track over which a vehicle is moved under its own power and remote exhaust testers which spectroscopically test exhaust emissions of vehicles as they move over the test track. The apparatus and method of the present invention preferably may be used for pre-screening vehicles as a first step in a testing process utilizing, as a second step, more extensive testing as with stationary testing apparatus.
Those vehicles clearly meeting minimum emissions standards can be relatively quickly screened out by the method and apparatus of the present invention and exempted from further, more extensive testing.
