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 exhaust redirect line in communication with an engine exhaust channel of a marine vehicle receiving exhaust gas. A blower unit in the exhaust redirect line directing the exhaust gas through the exhaust redirect line. A mixing chamber in communication with the exhaust redirect line receiving the engine exhaust gas. An injector unit in communication with the mixing chamber introducing a chemical agent, air and water into the mixing chamber to provide a treated exhaust gas. An output vane disposed on an exterior underside of a hull being in communication with the mixing chamber discharging the treated exhaust gas underneath the hull as a foam, whereby the engine exhaust gas is encapsulated and detoxified by the chemical agent in the foam to prevent the exhaust gas from entering the surrounding water and wherein the foam reduces friction between the hull and the surrounding water to improve engine efficiency.

What is claimed is: 1. A friction reducing pollution control system for marine vehicles comprising: an exhaust redirect line in communication with an engine exhaust channel receiving engine exhaust gas; a blower unit disposed in said exhaust redirect line directing said engine exhaust gas through said exhaust redirect line; a mixing chamber in communication with said exhaust redirect line receiving said engine exhaust gas; an injector unit in communication with said mixing chamber introducing a chemical agent, air and water into said mixing chamber to provide a treated exhaust gas; and, an output vane disposed on an exterior underside of a hull being in communication with said mixing chamber discharging said treated exhaust gas underneath the hull as a foam; whereby, said engine exhaust gas is encapsulated and detoxified by said chemical agent in said foam to prevent said exhaust gas from entering the surrounding water and wherein said foam reduces friction between said hull and the surrounding water to improve engine efficiency. 2. The system of claim 1, wherein said output vane includes an interior channel extending generally the length of said output vane receiving said treated exhaust gas so that said treated exhaust gas is distributed across the length of said output vane. 3. The system of claim 2, wherein said output vane is porous so that said treated exhaust gas is discharged along the entire length of said output vane in a foaming arrangement. 4. The system of claim 1, a pair of output vanes disposed in an opposing fashion on port and starboard sides of said exterior underside of said hull, wherein each of said output vanes is preferably angled rearwardly to extend generally outwardly from the keel towards the stern of said hull. 5. The system of claim 1, wherein said injector unit includes a chemical injector, an air injector, and a water injector each in fluid communication with said mixing chamber for introducing said chemical agent, said air and said water into said mixing chamber respectively to treat said engine exhaust gas. 6. The system of claim 1, wherein said blower unit is operatively associated with the engine so that the RPM of said blower unit is controlled by the RPM of the engine to adjust the speed of the blower unit to accommodate the exhaust volume output of the engine at varying RPMs to prevent blowback and excessive backpressure. 7. The system of claim 1, including a first exhaust feed line directing said engine exhaust gas from at least two said exhaust redirect lines into said mixing chamber. 8. The system of claim 7, including a blowback valve disposed in said first exhaust feed line to prevent said engine exhaust gas from backing up into said exhaust redirect lines. 9. The system of claim 1, wherein said injector unit is operatively associated with said engine so that the volume of the air, water and chemical agent injected into said mixing chamber is controlled by the engine RPM to maintain a volume of the air, water and chemical agent in said mixing chamber to treat all said engine exhaust gas directed into said mixing chamber. 10. The system of claim 1, including a second feed line exiting said mixing chamber and directing said treated exhaust gas into a through-hull fitting in fluid communication with said output vane to channel said treated exhaust gas into said output vane for being expelled underneath the hull. 11. The system of claim 10, including a back flush valve disposed in said through-hull fitting to prevent water from entering into said hull through said output vane. 12. A friction reducing pollution control system for marine vehicles comprising: an engine having an engine exhaust system disposed in a stern portion of the vehicle; an exhaust redirect line in communication with the engine exhaust system receiving engine exhaust gas from said engine exhaust system and channeling said engine exhaust gas towards a bow portion of the vehicle; a mixing chamber in communication with said exhaust redirect line receiving said engine exhaust gas; an injector unit introducing a chemical agent, air and water into said mixing chamber to provide a treated exhaust gas; and, an output vane disposed on an exterior underside of said hull generally towards said bow being in communication with said mixing chamber discharging said treated exhaust gas underneath the hull; whereby said treated exhaust gas produces a foam when discharged that prevents said exhaust gas from entering the surrounding water and reduces friction between said hull and the surrounding water to improve engine efficiency. 13. The system of claim 12 including a blower unit disposed in said exhaust redirect line directing said engine exhaust gas through said exhaust redirect line into said mixing chamber, wherein said blower unit is operatively associated with said engine so that the RPM of said blower unit is controlled by the RPM of said engine to adjust the speed of the blower unit to accommodate the exhaust volume output of said engine at varying RPMs to prevent blowback and excessive backpressure. 14. The system of claim 12, wherein said output vane includes an interior channel extending generally the length of said output vane receiving said treated exhaust gas so that said treated exhaust gas is distributed across the length of said output vane, and wherein said output vane is porous so that said treated exhaust gas is discharged along the entire length of said output vane. 15. The system of claim 12, wherein said injector unit includes a chemical injector, an air injector, and a water injector each in fluid communication with said mixing chamber for introducing said chemical agent, said air and said water into said mixing chamber respectively to treat said engine exhaust gas. 16. The system of claim 15, wherein each of said chemical injector, said air injector, and said water injector are operatively associated with said engine so that the volume of the air, water and chemical agent injected into said mixing chamber is controlled by the engine RPM to maintain a volume of the air, water and chemical agent in said mixing chamber to treat all said engine exhaust gas directed into said mixing chamber. 17. The system of claim 12, including a through-hull fitting in fluid communication with said output vane and said mixing chamber to channel said treated exhaust gas into said output vane for being expelled underneath the hull, wherein said through-hull fitting includes a back flush valve to prevent water from entering into said hull through said output vane.
