CONTROL OF REFUELING EMISSIONS WITH AN ACTIVATED CARBON CANISTER ON THE VEHICLE

To initiate the design of a prototype carbon canister system capable of handling refueling vapor losses, studies were undertaken on a bench-test system to define the total amount of refueling vapor to be handled, vapor retention capacity of activated carbon, and purge capacity over a range of refueling conditions and fuel system parameters. In addition, extensive exhaust and evaporative emission tests were performed on the baseline vehicle and the modified vehicle. Detailed cost and effectiveness analyses were performed. The study shows that this type of control is technically feasible for refueling and evaporative emissions, fuel savings can approach the cost of the refueling control system, driveability was not impaired, and exhaust CO emissions increased. /GMRL/
