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.

초록

A reformer controller is electrically coupled to both a fuel reformer and an engine control unit. The reformer controller is configured to communicate with the engine control unit to monitor an engine load signal between the engine control unit and an internal combustion engine. The reformer controller operates the fuel reformer in response to the engine load signal. A method of operating a fuel reformer is also disclosed.

1. A method of operating a fuel reformer, the method comprising the steps of:operating a fuel injector assembly in response to an injector signal from an engine control unit so as to inject fuel from the fuel injector assembly into an internal combustion engine but not into the fuel reformer, monitoring a signal between the internal combustion engine and the engine control unit, and operating the fuel reformer in response to the signal between the engine and the engine control unit, wherein the monitoring step further comprises monitoring an ignition timing signal output from the engine control module to the engine, the fuel reformer operating step includes generating a reformer control signal based on the ignition timing signal and sending the reformer control signal to the fuel reformer, and the generating step includes phase-shifting the ignition timing signal to create the reformer control signal. 2. A method of operating a fuel reformer, the method comprising the steps of:operating a fuel injector assembly in response to an injector signal from an engine control unit so as to inject fuel from the fuel injector assembly into an internal combustion engine but not into the fuel reformer, monitoring a signal between the internal combustion engine and the engine control unit, and operating the fuel reformer in response to the signal between the engine and the engine control unit, wherein the step of operating the fuel reformer comprises operating a plasma fuel reformer in response to the signal between the engine and the engine control unit. 3. The method of claim 2, wherein the operating step comprises adjusting an air-to-fuel ratio of an air/fuel mixture processed by the fuel reformer in response to the signal between the engine and the engine control module.4. The method of claim 2, wherein the monitoring step further comprises monitoring an ignition timing signal output from the engine control module to the engine.5. The method of claim 4, wherein the operating step includes generating a reformer control signal based on the ignition timing signal and sending the reformer control signal to the fuel reformer.6. The method of claim 2, wherein the monitoring step further comprises monitoring a throttle position signal input into the engine control unit from the engine.7. The method of claim 6, wherein the operating step includes generating a reformer control signal based on the throttle position signal and sending the reformer control signal to the fuel reformer.8. A method of operating a fuel reformer, the method comprising the steps of:operating a fuel injector assembly so as to inject fuel from the fuel injector assembly into an internal combustion engine but not into the fuel reformer, monitoring an engine load signal based on load of the internal combustion engine, generating a reformer control signal based on the engine load signal, and operating the fuel reformer based on the reformer control signal, wherein the step of operating the fuel reformer comprises sending the reformer control signal to a power supply associated with a plasma fuel reformer and operating the plasma fuel reformer based on the reformer control signal sent to the power supply. 9. The method of claim 8, wherein the engine load signal is an ignition timing signal sent from an engine control unit of the system to the engine.10. The method of claim 8, wherein the engine load signal is a throttle position signal sent from the engine to an engine control unit of the system.11. The method of claim 8, wherein the step of generating a reformer control signal includes phase-shifting the engine load signal.12. A power system comprising:a fuel reformer, a fuel injector assembly for injecting fuel into an engine but not into the fuel reformer, an engine control unit coupled to the engine and configured to generate an injector signal to control operation of the fuel injector assembly, and a controller electrically coupled to both the fuel reformer and the engine control unit wherein the controller comprises (i) a processor, and (ii) a memory device electrically coupled to the processor, the memory device having stored therein a plurality of instructions which, when executed by the processor, causes the processor to: (a) monitor a signal between the engine control unit and the engine; (b) generate a reformer control signal based on the signal between the engine control unit and the engine; and (c) operate the fuel reformer based on the reformer control signal, wherein the fuel reformer is a plasma fuel reformer. 13. The power system of claim 12, wherein the signal between the engine control unit and the engine is an ignition timing signal sent from the engine control unit to the engine.14. The power system of claim 13, wherein the plurality of instructions, when executed by the processor, cause the processor to generate the reformer control signal based on the ignition timing signal.15. The power system of claim 12, wherein the signal between the engine control unit and the engine is a throttle position signal sent from the engine to the engine control unit.16. The power system of claim 15, wherein the plurality of instructions, when executed by the processor, cause the processor to generate the reformer control signal based on the throttle position signal.17. A power system comprising:a fuel reformer, a fuel injector assembly for injecting fuel into an engine but not into the fuel reformer, an engine control unit coupled to the engine and configured to generate an injector signal to control operation of the fuel injector assembly, a controller electrically coupled to both the fuel reformer and the engine control unit wherein the controller comprises (i) a processor, and (ii) a memory device electrically coupled to the processor, the memory device having stored therein a plurality of instructions which, when executed by the processor, causes the processor to: (a) monitor a signal between the engine control unit and the engine; (b) generate a reformer control signal based on the signal between the engine control unit and the engine; and (c) operate the fuel reformer based on the reformer control signal, and an emissions abatement device fluidly coupled to the fuel reformer to receive reformate gas produced by operation of the fuel reformer based on the reformer control signal.
