Description
본 고안은 실린더 보어 사이의 실린더 블록의 냉각구조 개선에 관한 것이다.The present invention is directed to improving the cooling structure of the cylinder block between the cylinder bores.
일반적으로 실린더 블록의 온도가 적절히 높으면(150℃~160℃)오일의 점도가 적어지므로 출력향상의 잇점이 있으나 너무 높으면 실린더 보엉부의 변형유발, 오일유막파괴, 피스톤 핀 마모, 오일소모과다 등의 문제가 야기될 수 있다.In general, if the cylinder block temperature is adequately high (150 ℃ ~ 160 ℃), the oil viscosity decreases, but the output improves, but if it is too high, problems such as deformation of the cylinder bores, oil film breakdown, piston pin wear, excessive oil consumption, etc. May be caused.
그러나 실린더 블록 부위중 실린더 보어와 보어 사이의 부분, 특히 연소실에 접하는 상부면의 경우 냉각성이 불량하여 온도가 250℃까지 상승하는 경우가 있어 상기한 제반 문제를 유발하게 된다.However, the portion of the cylinder block portion between the cylinder bore and the bore, in particular, the upper surface in contact with the combustion chamber is poor in cooling, the temperature may rise to 250 ℃ causing the above problems.
이러한 문제를 해결하기 위하여 보어사이에 드릴공을 뚫어 워터재킷을 형성할 수도 있으나 이 경우 가공공정이 추가되고 벽두께가 두껍게 주조성형되어야 하므로 경제성 면에서 불리하다.In order to solve this problem, it is also possible to form a water jacket by drilling a drill hole between the bores. However, in this case, it is disadvantageous in terms of economics because a machining process is added and the wall thickness needs to be cast.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 실린더 보어 사이의 냉각성을 향상시킨 실린더블록의 냉각구조를 제공하는 데 있다.The present invention has been proposed in view of the above problems, and its object is to provide a cooling structure of a cylinder block with improved cooling between cylinder bores.
상기한 목적을 달성하기 위하여 본 고안은 실린더 블록의 냉각구조에 있어서, 실린더 보어 사이의 실린더 블록 상면에 열전도도가 좋은 알루미늄 보강대를 삽입한 것을 특징으로 한다.In order to achieve the above object, the present invention is characterized in that in the cooling structure of the cylinder block, an aluminum reinforcing rod having good thermal conductivity is inserted into the upper surface of the cylinder block between the cylinder bores.
도 1은 본 고안에 의한 실린더보어 사이의 실린더 블록의 냉각구조1 is a cooling structure of the cylinder block between the cylinder bore according to the present invention

이하 본 고안의 구성과 작용을 참조하여 설명한다.Hereinafter will be described with reference to the configuration and operation of the present invention.
도 1은 본 고안에 의한 실린더블록의 냉각구조를 나타내는 도면으로 도면중 부호1은 실린더블록이며, 부호 2와 3은 이웃하고 있는 실린더 보어이다.1 is a view showing a cooling structure of a cylinder block according to the present invention, wherein 1 is a cylinder block, and 2 and 3 are adjacent cylinder bores.
실린더 보어(2)(3) 사이의 실린더 블록(1)의 상부면, 즉 실린더헤드와 체결시 연소실에 가장 가까워 연소열의 영향을 가장 크게 받는 상부에 요홈을 형성한 후 열전도도가 좋은 알우미늄 보강대(4)가 매설되어 있다.Aluminum having good thermal conductivity after forming grooves in the upper surface of the cylinder block 1 between the cylinder bores 2 and 3, i.e., the uppermost portion closest to the combustion chamber when engaged with the cylinder head and thus greatly affected by the heat of combustion. The reinforcement stand 4 is embedded.
상기 알루미늄 보강대(4)는 주철로 주조되는 실린더블록(1)의 본체보다 열전도 계수가 약 5배(주철의 열전도계수 k≒30w/m°k)정도 크기 때문에 연소실의 열은 신속하게 전달하여 실린더 보어(2)(3) 사이의 온도를 낮출 수 있게 된다. 여기서 도면중 미설면 부호 5는 워터재킷이다.Since the aluminum reinforcing rod 4 has a thermal conductivity coefficient about 5 times larger than that of the main body of the cylinder block 1 cast of cast iron (heat conductivity coefficient k 연소 30w / m ° k of cast iron), the heat of the combustion chamber is quickly transferred to the cylinder. The temperature between the bores 2 and 3 can be lowered. In the drawing, the tongue surface 5 is a water jacket.
이상과 같은 본 고안에 의하면 실린더 보어 사이의 실린더 블록의 상부면에 열전도도가 우수한 알루미늄 보강대를 박아 넣으므로써 실린더 보어 사이의 취약부의 온도를 크게 낮추는 것이 가능하여 과열에 의한 실린더 보어의 뒤틀림이나 오일유막 파괴 및 오일소모 과다 등의 여러문제를 해결하게 되는 효과가 있다.According to the present invention as described above, by inserting an aluminum reinforcing rod having excellent thermal conductivity on the upper surface of the cylinder block between the cylinder bores, it is possible to greatly reduce the temperature of the weak part between the cylinder bores, so that distortion of the cylinder bore due to overheating or oil film It is effective in solving various problems such as destruction and excessive oil consumption.
