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 closed crankcase ventilation system for an internal combustion engine is disclosed. A compressor is configured to compress air and enhance the venting of crankcase emissions from a crankcase of the engine. A flow path is provided between the crankcase and an intake of the compressor. A prioritizing device is situated in the flow path and configured to regulate the flow of crankcase emissions and control pressure within the crankcase. A treatment element is provided downstream of the compressor and configured to treat the compressed air and crankcase emissions to remove entrained oil. A first conduit downstream of the treatment element is configured to introduce a first portion of the compressed air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine. A second conduit downstream of the treatment element is configured to introduce a second portion of the air and crankcase emissions into a system having at least one component utilizing compressed air for its operation.

What is claimed is: 1. A closed crankcase ventilation system for an internal combustion engine comprising: a compressor configured to compress air and enhance the venting of crankcase emissions from a crankcase of the engine; a flow path between the crankcase and an intake of the compressor; a prioritizing device configured to regulate the flow of crankcase emissions and control pressure within the crankcase; a treatment element downstream of the compressor configured to treat the air and crankcase emissions to remove entrained oil; a first conduit downstream of the treatment element configured to introduce a first portion of the air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine; and a second conduit downstream of the treatment element configured to introduce a second portion of the air and crankcase emissions into a system having at least one component utilizing compressed air for its operation. 2. The system of claim 1, wherein the prioritizing device is a valve situated in the flow path. 3. The system of claim 1, further including a cooling module downstream of the compressor and upstream of the treatment element. 4. The system of claim 1, further including a flow path for air between the air intake system for the engine and the intake of the compressor. 5. The system of claim 4, wherein the prioritizing device is a valve situated in the flow path between the crankcase and the intake of the compressor, and wherein the flow path for air between the air intake system for the engine and the intake of the compressor includes a conduit having one end connected to the air intake system for the engine and another end connected to the valve. 6. The system of claim 1, wherein the exhaust system for the engine includes an aftertreatment module for treating engine exhaust, and the first conduit is configured to introduce the first portion of the air and crankcase emissions into the exhaust system upstream of the aftertreatment device. 7. The system of claim 1, wherein the air intake system for the engine includes at least one turbocharger having a compressor section, at least one cooling module, and an intake manifold; and wherein the first conduit is configured to introduce a first portion of the air and crankcase emissions into the air intake system for the engine at one of a point upstream of the compressor section, and a point between the at least one cooling module and the intake manifold. 8. The system of claim 1, wherein the at least one component is a component of one of a braking system and an actuator. 9. The system of claim 1, including a flow path for directing entrained oil removed by the treatment element to the crankcase of the engine. 10. A method for closed crankcase ventilation, comprising: providing a flow path to vent crankcase emissions from the crankcase of an internal combustion engine; regulating flow of crankcase emissions and controlling pressure within the crankcase by a prioritizing device; using a compressor to enhance the flow of crankcase emissions through the flow path; compressing air and crankcase emissions from the crankcase; treating the compressed air and crankcase emissions to remove entrained oil; introducing a first portion of the treated air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine; and utilizing a second portion of the treated air and crankcase emissions to operate at least one component utilizing compressed air for its operation. 11. The method of claim 10, wherein regulating flow of crankcase emissions and controlling pressure within the crankcase by a prioritizing device includes providing a valve in the flow path. 12. The method of claim 10, further including providing a cooling module downstream of the compressor and cooling the compressed air and crankcase emissions before treating them. 13. The method of claim 10, further including providing a flow path for air between the air intake system for the engine and an intake of the compressor. 14. The method of claim 10, wherein regulating flow of crankcase emissions and controlling pressure within the crankcase by a prioritizing device includes providing a valve in the flow path to vent crankcase emissions from the crankcase, and further including: regulating the flow of air in the flow path between the air intake system and the intake of the compressor by the valve. 15. The method of claim 10, further including providing the exhaust system of the engine with an aftertreatment module and introducing the first portion of the treated air and crankcase emissions into the exhaust system of the engine at a location upstream of the aftertreatment module. 16. The method of claim 10, further including utilizing the second portion of the treated air and crankcase emissions to operate one of a braking system and an actuator. 17. A machine, comprising: a chassis; an engine mounted to the chassis and having a crankcase; at least one component associated with the machine and configured to utilize compressed air for its operation; a flow path configured to enable crankcase emissions to flow from the crankcase of the engine; a prioritizing device configured to regulate the flow of crankcase emissions and control pressure within the crankcase; a compressor configured to enhance the flow of crankcase emissions from the crankcase and compress air and crankcase emissions; a treatment element downstream of the compressor configured to treat air and crankcase emissions to remove oil; a first conduit downstream of the treatment element configured to introduce a first portion of the treated air and crankcase emissions into one of an exhaust system for the engine and an air intake system for the engine; and a second conduit downstream of the treatment element and configured to introduce a second portion of the treated air and crankcase emissions into a system for operating the at least one component. 18. The machine of claim 17, wherein the prioritizing device includes a valve situated in the flow path. 19. The machine of claim 17, wherein the at least one component associated with the machine and configured to utilize compressed air for its operation is a component of a braking system. 20. The machine of claim 17, further including a cooling module downstream of the compressor and upstream of the treatment element.
