Government agencies have become involved in vehicle maintenance through the initiation of periodic vehicle emission inspection requirements carried out at State or local levels. The key element in all vehicle engine maintenance, inspection and emission detection is the exhaust emission analyzer. Exhaust emission analyzers are presently available in many different designs, covering a broad price range and offering various capabilities and features. The objective of this study was to survey the market and identify all exhaust emission analyzer manufacturers, whose product could be used in vehicle inspection/maintenance (I/M) programs. Consequently, a representative group of instruments was selected and a series of tests were conducted to evaluate instrument performance. Major findings of this program: (1) A significant number of HC/CO I/M emission analyzers are presently available. (2) The vast majority of HC/CO instruments use an infrared absorption operating principle. (3) The hydrocarbon response characteristics of the HC/CO instruments generally showed greatest sensitivity to isobutylene, followed by toluene, methane, and ethylene. The units demonstrate essentially no sensitivity to acetylene and benzene.
