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, Kafe, Webinar 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.

A fuel selection device is provided for allowing a user to connect the cylinders of an internal combustion engine to a user-selected fuel source. The fuel selection device includes a housing that defines a cavity for receiving a moveable selector therein. The selector defining first, second, third and fourth flow paths. The first and second flow paths are used for flowing a first type (e.g., natural gas) of fuel from a fuel source to the cylinders of the engine. The second and fourth flow paths are used for flowing a second type of fuel (e.g., liquid propane vapor) from a fuel source to the cylinder. The selector is movable between a first position wherein first and second cylinders communicate with the first and second flow paths, respectively, and a second position wherein the first and second cylinders communicate with the second flow path and fourth flow paths, respectively.

We claim: 1. A fuel selection device for allowing a user to select a flow path for fuel to be provided to an engine, comprising: a first input conduit having a first end connectable to a user selected fuel source for receiving fuel therefrom and a second end; a selector switch having an input communicating with the second end of the first input conduit and an output, the selector switch movable between a first position wherein the input and the output of the selector switch communicate through a first flow path and a second position wherein the input and the output of the selector switch communicate through a second flow path; a second input conduit having a first end connectable to the user selected fuel source for receiving fuel therefrom and a second end; wherein the selector switch includes: a second input communicating with the second end of the second input conduit and a second output; and third and fourth flow paths, wherein the second input and second output of the selector switch communicate through the third flow path with the selector switch in the first position and the second input and second output of the selector switch communicating through the fourth flow path with the selector switch in the second position. 2. The fuel selection device of claim 1 wherein the selector switch includes a housing having a movable selector therein, the selector defining the first and second flow paths. 3. The fuel selection device of claim 2 wherein the selector extends along a longitudinal axis and wherein the selector is axially movable between the first and second positions. 4. In a engine fueled by a plurality of fuels, the engine having first and second cylinders, the improvement comprising: a selection device having first and second inputs operatively connected to a fuel source, a first output operatively connected to the first cylinder of the engine, and a second output operatively connected to the second cylinder of the engine, the selection device movable between: a first position wherein the first input and the first output of the selection device communicate through a first flow path and wherein the second input and the second output of the selection device communicate through a second flow path; and a second position wherein the first input and the first output of the selection device communicate through a third flow path and wherein the second input and the second output of the selection device communicate through a fourth flow path. 5. The improvement of claim 4 wherein the selection device includes: a housing extending along an axis and having an inner surface defining a cavity therein; a movable selector positioned within the cavity in the housing, the selector defining the first, second, third and fourth flow paths. 6. The improvement of claim 5 wherein the selector extends along the axis and wherein the selector is axially movable between the first and second positions. 7. The improvement of claim 5 wherein the housing defines a first closed end of the cavity and a second open and wherein the selector includes first and second opposite ends, the first end of the selector engaging the closed end of the cavity with the selector in the first position. 8. The improvement of claim 7 further comprising a stop interconnected to the housing and wherein the second end of the selector includes a shoulder formed therein, the shoulder engaging the stop with the selector in the second position. 9. The improvement of claim 4 further comprising: a first input conduit having a first end connectable to the user selected fuel source for receiving fuel therefrom and a second end operatively connected to the first input; a second input conduit having a first end connectable to the user selected fuel source for receiving fuel therefrom and a second end operatively connected to the second input. 10. The improvement of claim 4 wherein the selection device includes a third input and a third output, the third input communicating with the third output through a fifth flow path with the selection device in the first position. 11. A fuel selection device for allowing a user to connect a first and second cylinders of an engine to a user-selected fuel source, comprising: a housing defining a cavity; and a selector receivable in the cavity and defining first, second, third and fourth flow paths, the selector movable between: a first position wherein first cylinder communicates with the first flow path and the second cylinder communicates with the third flow path; and a second position wherein the first cylinder communicates with the second flow path and the second cylinder communicates with the fourth flow path. 12. The fuel selection device of claim 11 wherein the housing includes a first input connectable to the fuel source and a first output operatively connected to the first cylinder, the first input and the first output communicating with the first flow path with the selector in the first position and communicating with the second flow path with the selector in the second position. 13. The fuel selection device of claim 11 wherein the housing includes an inner surface defining the cavity and wherein the selector includes an outer surface that forms a slidable interface with the inner surface of the housing. 14. The fuel selection device of claim 13 wherein the selector includes a first end and a second end and wherein the fuel selection device includes a first seal extending about the outer surface of the selector between the first flow path and second end of the selector. 15. The fuel selection device of claim 11 further comprising first and second stops, the selector engaging the first stop with the selector in the first position and the selector engaging the second stop with the selector in the second position. 16. A fuel selection device for allowing a user to select a flow path for fuel to be provided to an engine, comprising: a first input conduit having a first end connectable to a user selected fuel source for receiving fuel therefrom and a second end; and a selector switch having an input communicating with the second end of the first input conduit and an output, the selector switch movable between a first position wherein the input and the output of the selector switch communicate through a first flow path and a second position wherein the input and the output of the selector switch communicate through a second flow path; wherein the first flow path is generally cylindrical and has a diameter and wherein the second flow path is generally cylindrical and has a diameter, the diameter of the first flow path being different than the diameter of the second flow path.
