Vehicle Exhaust Emissions Testing Programme The programme was implemented in Accra and Kumasi (two major cities in Ghana) ��Total Total number of vehicles tested - 2680 ��Gasoline Gasoline fuelled vehicles – 1660 ��Diesel Diesel fuelled vehicles - 1020
VEHICLE EMISSION TESTS Loaded Test • Vehicle is placed on a dynamometer (rolling treadmill) and run at various speeds and weights to simulate real driving conditions. • Probe inserted into tailpipe measures emissions—CO, HC, and NOx. • Test takes up to 10 minutes. No-Load Test • With vehicle stopped and idling, a probe is inserted into the tailpipe to measure emissions—CO and HC (not accurate for NOx). An additional measurement can be taken at a high idle speed. • Test takes less than 1 minute. Snap Idle Opacity Test for Diesel Engines • A no-load test for diesel engines in which the engine is revved several times • An average value of smoke opacity (or density) in the exhaust stream is derived.
