본 고안은 냉각성능이 향상된 차량의 실린더블럭 구조에 관한 것으로, 더욱 상세하게는 차량의 엔진에서 냉각성능을 증대시키기 위해 보어간에는 오일의 통로를 형성하여 냉각을 도모한 실린더블럭 구조에 관한 것이다.The present invention relates to a cylinder block structure of a vehicle with improved cooling performance, and more particularly, to a cylinder block structure for cooling by forming an oil passage between bores to increase cooling performance in an engine of a vehicle.
일반적으로 차량의 엔진에 있어서, 실린더내의 연소가스 온도는 상당히 고온이며, 이 열의 상당량은 실린더, 실린더헤드, 피스톤등으로 전달된다. 따라서, 엔진의 과열을 방지함과 동시에 피스턴이나 피스톤링같은 각각의 부품들이 일정온도 이상으로 상승되는 것을 방지함으로써 내구성을 증대시키고 그 기능을 최적화하기 의한 방안이 제안되고 있다. 특히, 최근에는 자동차엔진의 고출력화에 따라 엔진의 열부하가 증가되는 추세이며, 이러한 열부하의 증가에 따라 엔진의 냉각성능에 대한 중요성은 날로 커지고 있다. 엔진의 냉각성능은 엔진의 피로 및 마모등에 의한 엔진의 수명과 성능을 결정하는 중요한 인자가된다. 그러므로, 냉각성능이 향상되면 노킹현상이 감소됨에 따라 결과적으로 압축비를 높여 엔진의 효율과 출력을 증대시킬 수 있게된다.In general, in the engine of a vehicle, the combustion gas temperature in the cylinder is quite high, and a significant amount of this heat is transferred to the cylinder, cylinder head, piston, and the like. Therefore, a method of increasing durability and optimizing its function by preventing overheating of the engine and preventing respective components such as pistons and piston rings from rising above a certain temperature has been proposed. In particular, in recent years, the heat load of the engine increases with the increase of the output of the automobile engine, and the importance of the cooling performance of the engine is increasing day by day as the heat load increases. Engine cooling performance is an important factor in determining engine life and performance due to engine fatigue and wear. Therefore, when the cooling performance is improved, knocking is reduced, and as a result, the compression ratio can be increased to increase the efficiency and power of the engine.
또한, 엔진의 폭발시 발생되는 압력파와 고온에 의한 실린더 블럭의 열적변형으로 많은 량의 엔진오일이 소모되는 바, 냉각수를 이용하여 이를 효과적으로 제어하는 하나의 방안으로 샴(siamese)형식의 실린더블럭 구조가 개시되어 있다. 본 발명의 이해를 돕기 위해 첨부된 제1도를 참조하여 종래의 실린더블럭 구조에 대하여 설명하기로 한다.In addition, a large amount of engine oil is consumed due to the thermal deformation of the cylinder block due to the pressure wave and the high temperature generated when the engine explodes. As a way to effectively control this by using a coolant, a siamese type cylinder block structure is used. Is disclosed. A conventional cylinder block structure will be described with reference to the accompanying FIG. 1 for better understanding of the present invention.
제1도는 종래의 실린더블럭 구조를 나타내는 일부단면도로, 실린더블럭을 상방향에서 본 단면도이다.1 is a partial sectional view showing a conventional cylinder block structure, which is a sectional view of the cylinder block viewed from above.
제1도에 도시한 실린더블럭의 종래구조를 보면, 보어(10), (10')둘레에는 워터펌프로부터 송출된 냉각수가 유동하면서 피스톤 및 피스톤링을 냉각시키도록 구성된 워터자켓(12), (12')이 형성되어 있으며, 보어(10)와 보어(10')간에는 좌, 우측 워터자켓(12), (12')을 연결하는 냉각홀(14)이 형성되어 있다. 따라서, 보어간에 형성된 냉각홀(14)에 냉각수가 흐름에 따라서 보어내에 장치되는 피스톤이나 피스톤링들의 냉각을 도모하였다.Referring to the conventional structure of the cylinder block shown in FIG. 1, the water jacket 12, configured to cool the piston and the piston ring while the coolant discharged from the water pump flows around the bore 10, 10 '. 12 'is formed, and a cooling hole 14 connecting left and right water jackets 12 and 12' is formed between the bore 10 and the bore 10 '. Therefore, the cooling water 14 is formed in the bore between cooling the piston and the piston rings installed in the bore as the coolant flows.
그러나, 이러한 종래의 실린더블럭 구조에서는 보어의 직경이 증가함에 따라 냉각홀이 상대적으로 감소된다고 하는 점이외에도, 냉각수와 금속의 접촉에 의해 녹이나 침전물이 생기겨 냉각홀이 막히게 되며, 그로인해 엔진내의 온도가 상승함으로써, 보어내에 장치되는 피스톤이나 피스톤링과 같은 내부부품의 과열로 인해 냉각성능이 저하된다고 하는 문제가 있다.However, in the conventional cylinder block structure, in addition to the fact that the cooling holes are relatively reduced as the diameter of the bore increases, rust or sediment is formed by the contact of the cooling water and the metal, which causes the cooling holes to be blocked. As the temperature rises, there is a problem that cooling performance is lowered due to overheating of internal parts such as pistons and piston rings installed in the bore.
상술한 문제점을 감안하여, 본 고안의 목적은 엔진오일을 이용하여 보어내의 구성품들을 냉각함으로써 냉각성능을 향상시킬 수 있는 구조의 실린더블럭을 제공하는데 있다.In view of the above problems, an object of the present invention is to provide a cylinder block of a structure that can improve the cooling performance by cooling the components in the bore using the engine oil.
