SYSTEM AND METHOD FOR REMOTE ANALYSIS OF SMALL ENGINE VEHICLE EMISSIONS

摘要

A system and method of detecting gases in the exhaust of a moving vehicle with a small engine, such as a motorcycle or moped. The system employs a gas analyzer (101) with a beam (150) which makes more than two passes through a detection space (160). Through multiple passes through the detection space (160) the gas analyzer (101) generates a signal indicative of the concentrations of one or more components of interest in the exhaust plume. The system also includes a processor (140) for obtaining information about one or more vehicle exhaust components from the generated signal.
