Abstract

An exhaust gas measurement system for on-road use has been developed, which enables the direct and continuous determination of the exhaust gas mass emission rate from motor vehicles on the road. By using this system the instantaneous volume fraction of exhaust gases, air fuel ratio, engine speed, vehicle speed, fuel consumption rate and gear position were recorded during the test under realistic road conditions. The test was repeated many times. From the test results, a very informative view of the exhaust emissions behavior of a motor vehicle on the road was obtained, which is difficult to be simulated in laboratory tests.
