Abstract This report presents the results of a test program designed to quantify the change in the evaporative hydrocarbon emissions of six vehicles that (1) were tested before and after their carbon canisters were removed, and (2) were tested with the normal Certification test gasoline (Indolene unleaded) which is low in volatility, and a commercial gasoline of high volatility. The two fuels were used with the carbon canisters installed and with the carbon canisters removed. The test vehicle model years ranged from 1974 to 1983. When tested with Indolene gasoline, the diurnal and hot soak evaporative hydrocarbon emissions of all six vehicles increased when the carbon canisters were removed, but the increases varied widely from vehicle to vehicle. When tested with commercial gasoline, the hot soak evaporative hydrocarbon emissions of four of the six vehicles increased when the carbon canisters were removed, but again, the increases varied widely from vehicle to vehicle. The hot soak evaporative emissions of the other two vehicles did not significantly change. The diurnal evaporative emissions of all six vehicles increased when the carbon canisters were removed. The evaporative emissions of all six vehicles increased when the low volatility Indolene unleaded was replaced with the high volatility commercial gasoline.
