Abstract: A compressed time, one-hour test procedure was used to measure daily diurnal emissions from gasoline powered vehicles driven in a typical Nigerian urban city. The test showed that carburettor equipped vehicles on Nigerian roads emit about 19 times more fuel than that amount allowed by international standards during the standard diurnal test. They emit about 1.8 times more than that emitted by their counterparts in South Africa. The fuel injected vehicles emit 10.2 times more than that required by international standards and about 45 times more that that emitted by their counterparts equipped with pollution control devices. When compared with their counterparts in South Africa, they emit about 1.3 times more. Comparison of carburettor equipped vehicle and fuel injected one, showed that the former emits about 1.9 times more than the latter. The test also revealed that injected vehicles equipped with evaporative control equipment reduce fuel consumption and improve air quality.
