This study has assessed the effectiveness of current Evaporative Control Systems (ECS) and has shown the feasibility of various hardware approaches which control evaporative emissions to a very low level. The performance of ECS's in current use was evaluated by using the Sealed Housing for Evaporative Determinations (SHED) procedure on twenty 1973-75 cars with representative control systems. The measured emissions ranged from 0.5 to 30.6 grams per test, and the twenty car average was 8.7 grams per test. Hardware was then developed to improve ECS performance. Six production vehicles were modified to demonstrate the feasibility of improving current systems. These modifications were successful in lowering the evaporative emissions to less than 2.0 grams per test for each of the six modified vehicles. This six car group consisted of vehicles manufactured by General Motors, Ford, Chrysler, American Motors, Volvo and Mazda; and the costs of required hardware has been estimated at $2, $2, $6, $2, $2, and $25, respectively.
