Description

선박 엔진에 사용되는 실린더 헤드와 냉각수 순환 경로가 형성된 DF 엔진{Cylinder head used in ship engine and DF Engine with pathway of cooling water}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a DF engine having a cylinder head and a cooling water circulation path used in a marine engine,

본 발명은 선박 엔진에 사용되는 실린더 헤드와 냉각수 순환 경로가 형성된 DF 엔진에 관한 것으로, 보다 상세하게는 연소실에서 생성된 가스를 배기관으로 배출하는 실린더 가스 배출구의 구조와 엔진의 구조를 변경하여 조립 작업과 유지 보수의 편리성을 높일 수 있도록 한 것이다.
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a DF engine having a cylinder head and a cooling water circulation path used in a marine engine. More particularly, the present invention relates to a structure of a cylinder gas exhaust port, And convenience of maintenance.

선박 엔진에 사용되는 실린더 헤드에는 연소실에서 생성되는 배기 가스를 배출할 수 있도록 가스 배출구가 형성되며, 연소실과 가스 배출구 사이에는 배기밸브가 설치된다. 실린더 헤드는 연소실에서 생성되는 고온 고압의 가스를 견딜 수 있도록 제작되고 있다. 또한, 실린더 헤드의 가스 배출구 부분에 단열재를 장착하여 유지 보수시 작업자가 화상을 덜 입도록 한다.A cylinder head used in a marine engine is provided with a gas outlet for discharging the exhaust gas generated in the combustion chamber, and an exhaust valve is provided between the combustion chamber and the gas outlet. The cylinder head is manufactured to withstand the high-temperature, high-pressure gas generated in the combustion chamber. Further, a heat insulating material is mounted on the gas outlet portion of the cylinder head so that the operator wears less of the burden during maintenance.

현재 사용되고 있는 선박 엔진 중에는 도 4a에 도시한 바와 같이, 실린더 헤드(410)가 복수개인 중형 엔진이 있다. 이러한 중형 엔진은 실린더 헤드(410)의 가스 배출구에서 배출되는 고온 고압의 가스를 배기관(430)으로 안정적으로 배출하기 위해 실린더 헤드(410)와 배기관(430) 사이에 연결 파이프(Connection pipe)(420)가 장착된다. 연결 파이프(Connection pipe)(420) 역시 단열재를 장착하여 유지 보수시 작업자가 화상을 덜 입도록 한다. Among the currently used marine engines, there is a medium-sized engine having a plurality of cylinder heads 410, as shown in FIG. 4A. This medium-sized engine is provided with a connection pipe 420 between the cylinder head 410 and the exhaust pipe 430 for stably discharging the high-temperature high-pressure gas discharged from the gas outlet of the cylinder head 410 to the exhaust pipe 430 Is mounted. The connection pipe 420 is also equipped with a thermal insulation material so that the operator is less burdened during maintenance.

그런데, 중형 엔진에 사용되는 실린더 헤드(410)와 연결 파이프(Connection pipe)(420)에 단열재를 장착하고 실린더 헤드(410)와 연결 파이프(Connection pipe)(420) 유지보수 시 단열재를 분해해야 하기 때문에 작업 공수가 많아져 작업이 번거로운 문제점이 있었다. However, it is necessary to disassemble the insulator when installing the insulator in the cylinder head 410 and the connection pipe 420 used in the medium-sized engine and maintenance of the cylinder head 410 and the connection pipe 420 Therefore, there is a problem that the work is troublesome because the work flow increases.

한편, 선박에서는 화물 적재 공간과 선박용 이중연료(Dual Fuel) 엔진 사용 시 압축기와 기타 열교환 장비를 위한 엔진 룸의 공간이 협소해질 수밖에 없다. 향후 엔진 설비에서는 출력과 연비의 향상, 엔진 구조물을 축소하되 엔진 및 부속 시설에 대한 조립성 및 유지 보수성을 향상시킬 수 있는 과제를 해결해야 한다.
On the other hand, the space of the engine room for compressors and other heat exchanging equipment becomes narrow when the cargo loading space and the ship dual fuel engine are used. Future engine installations should address the challenges of improving output and fuel economy, reducing engine construction, and improving assembly and maintainability of engines and associated facilities.
