연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

1. A fuel tank cap that is removably coupled to a fuel tank of an engine, the fuel tank cap comprising: a fuel cap cover;a housing having a side wall, a bottom wall, and a receptacle;a fuel vapor adsorption material positioned within the receptacle;an inlet disposed near the bottom wall and configured to provide fluid communication with a fuel tank vapor space;an outlet disposed near the bottom wall and configured to provide fluid communication with the atmosphere;a radially extending internal wall adjacent the bottom wall, the inlet and the outlet being disposed on opposite sides of the internal wall; andat least one aperture configured to permit fuel vapor to flow in a vapor flow path from one side of the internal wall to the other side of the internal wall. 2. The fuel tank cap of claim 1, wherein the fuel vapor adsorption material includes activated carbon. 3. The fuel tank cap of claim 1, wherein the vapor flow path is substantially circular. 4. The fuel tank cap of claim 1, wherein the internal wall is a first internal wall, and wherein the fuel tank cap further includes at least two additional radially extending internal walls adjacent the bottom wall and contiguous with the first internal wall. 5. The fuel tank cap of claim 4, wherein each of at least two additional radially extending internal walls has an aperture configured to permit passage of fuel vapor through the respective internal wall. 6. The fuel tank cap of claim 5, wherein the at least two additional radially extending internal walls includes at least three radially extending internal walls, and wherein a combination of the first internal wall and the at least three additional radially extending internal walls has a substantially X-shaped configuration. 7. The fuel tank cap of claim 5, wherein a combination of the first internal wall and the at least two additional radially extending internal walls has a substantially Y-shaped configuration. 8. The fuel tank cap of claim 1, wherein the internal wall extends from the bottom wall. 9. The fuel tank cap of claim 1, wherein the inlet is disposed in the bottom wall, and wherein the outlet is disposed in one of the bottom wall and the side wall. 10. The fuel tank cap of claim 1, wherein the fuel tank cap includes a mounting apparatus configured to receive a fuel additive capsule. 11. The fuel tank cap of claim 10, wherein the mounting apparatus is positioned on an opposite side of the bottom wall from the internal wall. 12. The fuel tank cap of claim 5, wherein the apertures are non-adjacent to the side wall. 13. A fuel tank cap that is removably coupled to a fuel tank of an engine, the fuel tank cap comprising: a fuel cap cover;a housing having a side wall, a bottom wall, and a receptacle;a fuel vapor adsorption material positioned within the receptacle;a fuel vapor inlet disposed near the bottom wall and configured to provide fluid communication with a fuel tank vapor space;an outlet disposed near the bottom wall and configured to provide fluid communication with the atmosphere;a radially extending internal wall adjacent the bottom wall, the inlet and the outlet being disposed on opposite sides of the internal wall, the internal wall creating a first region on one side of the internal wall and a second region on the other side of the internal wall; andat least one aperture configured to permit fuel vapor to flow in a fuel vapor flow path from the first region to the second region. 14. The fuel tank cap of claim 13, wherein the fuel vapor adsorption material includes activated carbon. 15. The fuel tank cap of claim 13, wherein the fuel vapor flow path is substantially circular. 16. The fuel tank cap of claim 13, wherein the internal wall is a first internal wall, and wherein the fuel tank cap further includes at least two additional radially extending internal walls adjacent the bottom wall and contiguous with the first internal wall. 17. The fuel tank cap of claim 16, wherein each of at least two additional radially extending internal walls has an aperture configured to permit passage of fuel vapor through the respective internal wall. 18.
