Abstract
This paper reports the quantification of the evaporative emissions from gasoline-poweredmotor vehicles in South
Africa under various conditions including high temperatures. Three vehicles with and without evaporative emission
control systems have been tested to quantify gasoline evaporative emissions, including both diurnal and running loss
emissions. Measurements were made in a Sealed Housing for Evaporative Determination over a range of ambient
temperatures. The standard diurnal test shows that evaporative emissions increase progressively with increasing fuel
temperature. South African gasoline poweredmotor vehicles exhibitedevaporative emissions 10 times higher than that
allowed by the United States Environmental Protection Agency. The extended-time diurnal test shows that the fuel
emittedfrom gasoline-poweredmotor vehicles in South Africa is about 97 million litres of gasoline every year.
