차량의 EEC시스템에서의 탄화수소 중기 발생량 예측을 위한 연구 = The Study of Predicting Hydrocarbon Vapor Generation in the Automotive Evap0orative Emission Control System

다국어 초록 (Multilingual Abstract)

The hydrocarbon(HC) emission from automotive vehicles has been named as a source of the ozone layer depletion. Therefore, the importance of Evaporative Emission Control(EEC) system which can reduce HC emission is brought forward. EEC system is composed of a fuel tank.a fuel-returning line. a roll-over valve. an orifice for pressure reguJatiolL tubes. and a canister. TIle canister is a centerpiece of EEC system that captures HC vapor escaping into the aunospllCre and its optimum capacity is decided by the amount of HC vapor generated during test periods. In this study, the mathematical model of the HC vapor generation in EEC system was constructed and solved accordingto testing conditions. TllC fuel vapor was considered as an ideal gas mixture of 35 different HC species .The pressure rise in the tank due to vapor generation causes the mixture of the fuel vapor and the air to pass through EEC system including the canister. The Reid Vapor Pressure(RVP) decrease of the remaining fuel was calculated and the amount of vapor generated in the lank and captured in the canister was predicted.!n addition,the obtained results were compared with <br/>
. experimental results<br/>
