본 고안은 다기통내연기관의 실린더블럭에 관한 것으로, 특히 블로바이개스통로 입구와 오일통로 출구가 실린더블럭의 하면보다 윗쪽에 형성되어 블로바이개스와 오일의 순환이 원활하도록 된 다기통내연기관의 롱스커트타입(Long Skirt Type) 실린더블럭에 관한 것이다.The present invention relates to a cylinder block of a multi-cylinder internal combustion engine, and in particular, a blow-by gas passage inlet and an oil passage outlet are formed above the lower surface of the cylinder block so that the circulation of the blow-by gas and oil is smooth. A long skirt type cylinder block.
종래의 일반적인 다기통엔진의 실린더블럭은, 실린더헤드나 터보챠져 또는 오일필터등으로 드레인되는 윤활오일이 크랭크케이스의 오일팬으로 직접 떨어지도록 되어 있어서, 오일이 크랭크샤프트나 주변회전체등에 부딪혀 흩어지면서 공기가 혼입되어 거품이 발생하기 때문에, 이 오일을 다시 펌핑해서 사용한 경우에는 윤활효과가 현저히 저하된다고 하는 것이 문제로 되고 있다.The cylinder block of the conventional general multi-cylinder engine is such that the lubricating oil drained by the cylinder head, the turbocharger or the oil filter falls directly on the crankcase oil pan, so that the oil hits the crankshaft or the peripheral rotor and scatters. Since air mixes and bubbles are generated, the problem is that the lubrication effect is remarkably lowered when this oil is pumped and used again.
이에 본 고안은 상기와 같은 문제점을 해소하기 위해 안출된 것으로, 블로바이개스통로입구와 오일통로출구의 위치를 실린더블럭 하단면보다 위쪽으로 일정간격을 두고 위치시켜줌으로써 블로바이개스와 오일의 순환동작이 원활하게 이루어지도록 된 다기통내연기관의 롱스커트타입 실린더블럭을 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, by placing the position of the blow-by gas passage inlet and the oil passage exit at a predetermined interval above the lower surface of the cylinder block circulation operation of the blow-by gas and oil The purpose is to provide a long skirt type cylinder block of a multi-cylinder internal combustion engine to be made smoothly.
상기와 같은 목적을 달성하기 위한 본 고안은, 실린더블럭의 각 실린더호올 사이에 있는 격벽의 양쪽 코너에 형성된 통로를 통로를 통과하고 나서 오일팬으로 신속하게 귀환될 수 있음과 더불어 블로바이개스가 블로바이개스통로로 신속하게 빠져나갈수 있게 된다.The present invention for achieving the above object, through the passage formed in both corners of the partition wall between each cylinder of the cylinder block through the passage can be quickly returned to the oil pan and blow-by gas blow You can quickly exit the bygas passage.
이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1도와 제2도는 실린더블록(1)의 평면도 및 저면도로서, 각 실린더호올(2) 사이의 격벽부(3)양쪽에 이 실린더블록(1)을 실린더헤드(도시안됨) 및 크랭크케이스(도시안됨)와 연결시켜주는 보울트구멍(4,5)이 다수개 형성되어 있다.1 and 2 are a plan view and a bottom view of the cylinder block 1, wherein the cylinder block 1 is placed on both sides of the partition 3 between each cylinder column 2, and the cylinder head (not shown) and the crankcase ( A plurality of bolt holes 4 and 5 are formed to connect with each other.
그리고 제3도는 제1도의 III-III선을 따른 단면도로서, 이 실린더블럭(1) 한쪽 측벽에는 실린더헤드의 오일통로와 크랭크에시의 내부공간을 연결시켜주는 오일통로(6)가 형성되고, 다른 한쪽 측벽에는 연소실로부터 실린더 내벽면과 실린더링 사이로 누출되어 크랭크케이스쪽으로 내려가는 블로바이(Blow-by)개스가 연소실로부터 직접 배출되는 개스와 함께 배출시켜지도록 블로바이개스통로(7)가 형성되어 있으며, 상기 실린더호올(2) 2개가 각각 오일통로(6)와 블로바이개스통로(7)를 공유하도록 되어있다.3 is a cross-sectional view taken along line III-III of FIG. 1, and on one side wall of the cylinder block 1, an oil passage 6 connecting the oil passage of the cylinder head and the internal space of the crank ash is formed. On the other side wall, a blow-by gas passage 7 is formed so that a blow-by gas leaking from the combustion chamber between the cylinder inner wall surface and the cylinder ring and descending to the crankcase is discharged together with the gas discharged directly from the combustion chamber. The two cylinder hoses 2 share the oil passage 6 and the blow-by-gas passage 7, respectively.
또한 상기 아랫쪽 보울트구멍(5) 사이에는 크랭크샤프트(도시안됨)가 미끄럼 접촉되는 크랭크샤프트지지부(8)가 형성되고, 상기 실린더호올(2)주위에는 냉각수쟈켓(9)이 형성되며, 이 냉각수쟈켓(9)아랫쪽 한쪽에는 상기 크랭크샤프트지지부(8)로부터 각종 베어링에 오일을 공급시켜주는 오일갤러리(10)가 형성되어 있다.In addition, a crankshaft support portion 8 is formed between the lower bolt hole 5 in which the crankshaft (not shown) is in sliding contact, and a coolant jacket 9 is formed around the cylinder hose 2. (9) On the lower side, an oil gallery 10 for supplying oil to various bearings from the crankshaft support portion 8 is formed.
또, 상기 오일통로(6)와 블로바이개스(7)의 하단면(6a,7a)이 실린더블럭(1)의 하단면(1a)보다 소정의 간격을 두고 윗쪽에 위치되고, 이 실린더블럭(1)의 하단면(1a)과, 상기 오일통로(6)와 블로바이개스(7)의 하단면(6a,7a) 사이에는 경사면(10)이 형성되어 있다.The lower end surfaces 6a and 7a of the oil passage 6 and the blow-by gas 7 are located above the lower end surface 1a of the cylinder block 1 at a predetermined interval, and the cylinder block ( An inclined surface 10 is formed between the lower end surface 1a of 1) and the lower end surfaces 6a and 7a of the oil passage 6 and the blow-by gas 7.
이와 같이 구성된 본 고안은, 실린더헤드로부터 드레인되는 윤활오일이 실린더블럭(1)의 한쪽 측벽에 형성된 오일통로(6)를 타고 아랫쪽으로 내려와 오일통로(6)의 하단면(6a)을 지나 경사면(10)을 통과하여 크랭크케이스의 내부공간인 오일팬으로 드레인되기 때문에, 오일이 오일팬으로 자유낙하해서 떨어지거나 크랭크샤프트에 부딪히지 않게 되므로 거품이 형성되어 오일에 공기가 혼입되는 현상이 일어나지 않게 되어, 이 오일을 다시 펌핑해서 사용하더라도 오일내에 기포형성에 의한 윤활효과 저하현상이 일어나지 않게 된다.According to the present invention configured as described above, the lubricating oil drained from the cylinder head descends downward through the oil passage 6 formed on one side wall of the cylinder block 1 and passes over the lower end 6a of the oil passage 6 to the inclined surface ( Since it passes through 10) and drains into the oil pan, which is the inner space of the crankcase, oil does not fall freely into the oil pan and fall or hit the crankshaft, so bubbles do not form and air is not mixed in the oil. Even if this oil is pumped and used again, the lubrication effect is not reduced by the bubble formation in the oil.
한편, 연소실로부터 실린더내벽면과 실린더링사이로 누출되어 크랭크케이스쪽으로 내려오는 블로바이개스는, 상기 실린더블럭(1)의 다른 한쪽 블로바이개스통로(7)와 실린더헤드의 오일통로를 통과해서 연소실로부터 직접 배출되는 개스와 함께 배출되게 된다.On the other hand, the blow-by-gas leaking from the combustion chamber between the cylinder inner wall surface and the cylinder ring and descending toward the crankcase passes through the other blow-by-gas passage 7 of the cylinder block 1 and the oil passage of the cylinder head from the combustion chamber. It will be discharged with the gas being discharged directly.
이때, 상기 블로바이개스통로(7)의 하단면(7a)이 실린더블럭(1)의 하단면(1a)보다 윗쪽에 위치됨으로써, 연소실로부터 누출되는 블로바이개스가 곧바로 이 통로(7)를 통해 배출되므로, 블로바이개스의 배출이 빨라지게 된다.At this time, the lower surface 7a of the blow-by-gas passage 7 is located above the lower surface 1a of the cylinder block 1, so that the blow-by-gas leaking from the combustion chamber is immediately passed through the passage 7. As it is discharged, the discharge of the blow-by-gas becomes faster.
또한, 본 고안에 따른 실린더블록(1) 에 오일통로(6)와 블로바이개스통로(7)가 구획됨으로 해서, 오일의 방향과 블로바이개스의 방향이 서로 반대가 되면서 간섭이 일어나는 현상을 배제시켜 오일과 블로바이개스의 흐름을 원활하게 해주게 된다.In addition, since the oil passage 6 and the blow-by-gas passage 7 are partitioned in the cylinder block 1 according to the present invention, the oil direction and the blow-by-gas direction are opposite to each other, thereby eliminating the phenomenon of interference. This will make the flow of oil and blow-by-gas smooth.
이상 설명한 바와 같이, 본 고안은 실린더블럭(1)양쪽 측벽에 오일통로(6)와 블로바이개스통로(7)가 대칭적으로 형성됨과 동시에 이 오일통로(6)와 블로바이개스통로(7)의 하단면(6a,7a)이 실린더블럭(1)의 하단면(1a)보다 윗쪽에 위치됨으로써 실린더헤드에서 누출되는 오일이 원활하게 드레인시켜지게 되고 블로바이개스도 쉽게 배출시켜지는 효과가 있다.As described above, in the present invention, the oil passage 6 and the blow-by-gas passage 7 are symmetrically formed on both sidewalls of the cylinder block 1, and at the same time, the oil passage 6 and the blow-by-gas passage 7 are formed. Since the bottom surfaces 6a and 7a of the cylinder block 1 are positioned above the bottom surface 1a of the cylinder block 1, the oil leaking from the cylinder head is smoothly drained and the blow-by-gas is easily discharged.
