It is provided with a coolant passage 21 formed in the upper portion of the outer peripheral surface of the cylinder liner 20 so as to communicate with (23b) to pass through the coolant.

또한 상기 입구부(23a)와 출구부(23b)는 비동심원이 되도록 형성되고, 특히 이 입구부(23a)와 출구부(23b)는 도 3에 도시된 바와 같이, 챔퍼(chamfer) 가공에 의해 비동심원이 된다. 따라서 상기 냉각수 통로(21)는 실린더 라이너(20)의 상부 외주면에 형성된 플랜지(flange)(22)에 의해 마련되며, 상기 입구부(23a)와 출구부(23b)는 이 플랜지(22)의 챔퍼 가공에 의해 형성된다.In addition, the inlet portion 23a and the outlet portion 23b are formed to be non-concentric. In particular, the inlet portion 23a and the outlet portion 23b are formed by chamfering, as shown in FIG.

또한 상기와 같이 구비된 주냉각통로의 일측에는 도 5에 도시된 바와 같이, 실린더 블록(30)의 상부에 배치된 실린더 헤드(미도시)로 냉각수가 배출되도록 연결된 메인 출구부(25)가 구비된다. 그리고 상기 주냉각통로의 타측에는 주냉각통로로 냉각수가 공급되도록 하는 외부 워터자켓(28)이 구비된다.In addition, one side of the main cooling passage provided as described above is provided with a main outlet portion 25 connected to discharge the coolant to the cylinder head (not shown) disposed above the cylinder block 30, as shown in FIG. do. And the other side of the main cooling passage is provided with an external water jacket 28 to supply the cooling water to the main cooling passage.

한편, 도 2 내지 도 5에서 설명되지 않은 도면부호 'A'는 냉각수의 흐름을 나타내 보인 것이고, 26 및 27은 실린더 블록(30)에 마련되어 상기한 주냉각통로와 연통된 제1,2주냉각실을 나타내 보인 것이다.On the other hand, reference numeral 'A', which is not described in FIGS. 2 to 5, indicates the flow of the cooling water, and 26 and 27 are provided in the cylinder block 30 to communicate with the main cooling passages described above. It shows the thread.

상기한 바와 같은 구성을 갖는 본 발명에 따른 엔진의 실린더 블록 상부 냉각구조의 작용을 설명하면 다음과 같다.Referring to the operation of the cylinder block upper cooling structure of the engine according to the present invention having the configuration as described above are as follows.

도면을 다시 참조하면, 본 발명에 따른 엔진의 실린더 블록 상부 냉각구조는, 엔진의 실린더 블록(30) 및 실린더 라이너(20)의 상부를 냉각하기 위한 구조로, 실린더 라이너(20)를 동심 및 비동심원으로 가공 즉, 냉각수의 입구부(23a) 및 출구부(23b)를 비동심원으로 가공하여 실린더 라이너(20)의 상부 원둘레에 냉각수를 순환시키는 냉각수 통로(21)와 연통된다.Referring back to the drawings, the cylinder block upper cooling structure of the engine according to the present invention is a structure for cooling the upper portion of the cylinder block 30 and the cylinder liner 20 of the engine, concentric and non-concentric cylinder liner 20 Processing concentrically, i.e., processing the inlet 23a and outlet 23b of the coolant into a non-concentric circle and communicates with the coolant passage 21 for circulating the coolant in the upper circumference of the cylinder liner 20.

구체적으로는, 상기 실린더 라이너(20)의 상부 외주면에 플랜지(22)를 형성하여 냉각수 통로(21)가 구비되게 하고, 이 플랜지(22)의 외주면을 챔퍼 형상으로 가공하여, 냉각수를 실린더 블록(30)의 상부로 유입되게 하고, 다시 배출되게 하는 냉각수의 입구부(32a) 및 출구부(23b)를 형성하여 상기 냉각수 통로(21)와 연통되게 한다.Specifically, a flange 22 is formed on the upper outer circumferential surface of the cylinder liner 20 so that the cooling water passage 21 is provided, and the outer circumferential surface of the flange 22 is processed into a chamfer shape to cool the coolant to a cylinder block ( An inlet portion 32a and an outlet portion 23b of the coolant to be introduced into the upper portion of the 30 and to be discharged again are formed to communicate with the coolant passage 21.

이에 따라 상기 냉각수 통로(21)는 실린더 라이너(20)의 최상부 둘레에 동심으로 위치되어 냉각수가 제1,2주냉각실(냉각 갤러리)(26,27) 둘레를 동시에 순환할 수 있게 하는 2차 냉각실을 제공하게 한다. 그러나, 이때 냉각수가 상기 제1,2주냉각실(26,27)을 거쳐 유출되는 것은 아니다. Accordingly, the coolant passage 21 is located concentrically around the top of the cylinder liner 20 so that the coolant can circulate simultaneously around the first and second main cooling chambers (cooling gallery) 26, 27. To provide a cooling chamber. However, the cooling water does not flow out through the first and second main cooling chambers 26 and 27 at this time.

그리고 상기 2차냉각실을 이루는 출구부(23b)가 제1,2주냉각실(26,27) 각 출 구와 연결되며, 제1,2주냉각실(26,27)로부터의 냉각수가 제1,2주냉각실(26,27)의 출구를 통해 흐르게 된다. 그러나, 냉각수가 상기 제1,2주냉각실(26,27)에서 유입되는 것은 아니고, 외부 워터자켓(28)으로부터 동시에 제1,2주냉각실(26,27)과 공급되는 구조이다.The outlet 23b constituting the secondary cooling chamber is connected to each outlet of the first and second main cooling chambers 26 and 27, and the coolant from the first and second main cooling chambers 26 and 27 is first The two main cooling chambers 26 and 27 flow through the outlets. However, the cooling water does not flow into the first and second main cooling chambers 26 and 27, but is supplied to the first and second main cooling chambers 26 and 27 simultaneously from the external water jacket 28.

이에 따라 상기 실린더 라이너(20)의 최상부에서 실린더 라이너(20) 단위 면적당 열에너지를 매우 큰 비율로 제거하게 된다.Accordingly, a very large ratio of thermal energy per unit area of the cylinder liner 20 is removed at the top of the cylinder liner 20.

또한 상기와 같은 실린더 라이너(20)의 주냉각통로를 형성함에 따라 구체적으로 도시되지는 않았지만 도 2에 개략적으로 도시된 바와 같이, 냉각수가 입출 되도록 냉각수 입구 및 출구가 형성된다.In addition, as the main cooling passage of the cylinder liner 20 as described above, although not specifically illustrated, as shown schematically in FIG. 2, the coolant inlet and the outlet are formed to allow the coolant to enter and exit.

상술한 바와 같이 본 발명에 따른 엔진의 실린더 블록 상부 냉각구조는 다음과 같은 효과를 갖는다.As described above, the cylinder block upper cooling structure of the engine according to the present invention has the following effects.

열부하가 큰 실린더 블록의 상부가 냉각수에 의해 집중 냉각이 이루어짐으로써, 실린더 블록의 열변형 및 실린더 라이너와 피스톤의 열변형이 개선될 수 있다.By the centralized cooling of the upper portion of the cylinder block having a large heat load by the cooling water, the thermal deformation of the cylinder block and the thermal deformation of the cylinder liner and the piston can be improved.
