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.

An improved spark ignition system for an internal combustion engine that includes a pair of electrodes disposed to extend from opposite sides and into a combustion chamber to form a spark gap between them that is central to the combustion chamber. Each electrode is integral with a conductive fuel delivery tube that contains a capillary passage and fuel outlet ports adjacent the electrode. The heat from combustion conducted into the electrodes and fuel delivery tubes is used to vaporize the fuel within the capillary passages before it exits the outlet ports as an atomized fog into the combustion chamber adjacent the spark gap. The vaporization of the fuel flowing in the capillary passages absorbs energy from the electrodes and thus performs a cooling effect on the electrodes. The spacing of the electrodes from opposite sides of the cylinder also allows a design that can utilize and increased spark gap to produce a larger spark across the gap.

We claim: 1. A system for producing a spark in a combustion chamber in a cylinder of an internal combustion engine comprising: a pair of electrodes extending into the combustion chamber portion of a cylinder; said electrodes having tips opposing each other across a spark gap of a predetermined distance; said electrodes each being supported by and integral with a separate fuel delivery tube of electrically conductive material and each fuel delivery tube having a capillary tubular passage to allow the flow of fuel therethrough; said electrodes being located at the ends of said tubes and said tubes having a plurality of ports in communication with said capillaries and adjacent said electrodes for allowing the injection of fuel into said combustion chamber adjacent said spark gap. 2. A system as in claim 1, wherein said electrodes extend into the combustion chamber portion of a cylinder from opposite sides of said cylinder. 3. A system as in claim 2, wherein said electrodes extend into the combustion chamber portion of a cylinder from opposite sides of said cylinder and are coaxial with each other. 4. A system as in claim 1, wherein said electrodes each extend into the combustion chamber portion of a cylinder along a radial towards the center of said chamber at an angle to each other. 5. A system as in claim 1, wherein said electrodes and said fuel delivery tubes are electrically isolated from the common ground potential of said engine. 6. A system as in claim 1, wherein said electrodes are cooled by the flow of fuel through said capillaries and said ports. 7. A system as in claim 1, wherein said electrically conductive fuel delivery tube is formed of a material from the group including nickel and stainless steel. 8. A system as in claim 1, further including a source of pressurized fuel, a controlled injector metering valve, and a check valve associated with each capillary tube, wherein each said check valve is located between said metering valve and said associated capillary tube to prevent combustion pressures created in said combustion chamber from adversely affecting said metering valve. 9. A fuel injector tube and spark electrode combination including a threaded connector housing for connecting said combination to a correspondingly threaded port on the cylinder of an internal combustion engine; an electrically conductive capillary tube extending from said housing, a single electrode tip carried at the end of said capillary tube; an electrical connector on said housing being electrically connected to said capillary tube and said electrode tip; a fuel line connection on said housing being in communication with said capillary tube to allow fuel provided from a pressurized source to flow into said capillary tube; said capillary tube containing at least one opening adjacent said electrode tip to allow said fuel to exit said capillary tube, wherein a plurality of said combinations are employed in an internal combustion engine in opposition to provide an air gap between opposing single electrode tips and applying an electrical potential to each electrical connector at a predetermined time in the cycle of said engine sufficient to generate an arc across said air gap. 10. The combination of claim 9, wherein each said capillary tube contains a plurality of openings immediately adjacent to said single electrode tip. 11. The combination of claim 9, wherein each said capillary tube, said electrode tip, said electrical connector, and said fuel line connection are electrically isolated from said connector housing. 12. The combination of claim 9, wherein a pair of said combinations is employed in the cylinders of an opposing piston opposing cylinder internal combustion engine and each electrode is positioned to define said gap near the center of the cylinder in a defined combustion chamber. 13. The combination of claim 12, wherein the fuel exiting said capillary tube openings adjacent each said electrode tip is atomized and generates an air/fuel cloud mixture that surrounds said gap. 14. The combination of claim 13, wherein said electrical potential is isolated from ground that is in common with the cylinders of said engine. 15. The combination of claim 12, wherein each of said electrodes extend into the combustion chamber portion of a cylinder from opposite sides of said cylinder. 16. The combination of claim 12, wherein each of said electrodes extend into the combustion chamber portion of a cylinder from opposite sides of said cylinder and are coaxial with each other. 17. The combination of claim 12, wherein each of said electrodes extend into the combustion chamber portion of a cylinder along a radial towards the center of said chamber at an angle to each other. 18. The combination of claim 12, wherein said electrodes are cooled by the flow of fuel through said capillaries and said ports. 19. The combination of claim 12, further including a source of pressurized fuel, a controlled injector metering valve, and a check valve associated with each capillary tube, wherein each said check valve is located between said metering valve and said associated capillary tube to prevent combustion pressures created in said combustion chamber from adversely affecting said metering valve. 20. A spark gap ignition system for an internal combustion engine comprising: a first electrode mounted on the cylinder of said engine and having a single tip that extends into the combustion chamber of said cylinder; a second electrode mounted on said cylinder of said engine and having a single tip that extends into said combustion chamber of said cylinder; said tips of said first and second electrodes are mounted on said cylinder in opposition to each other to provide spark gap therebetween of a predetermined distance; each electrode contains a fuel delivery tube extending along its length from a fuel supply outside said cylinder to a fuel injection opening in said tip; said tips of said first and second electrodes supporting said electrical discharge across said gap and the injection of fuel through said openings and into said spark gap.
