본 발명은 자동차용 내연기관의 실린더헤드에 관한 것으로서, 더욱 상세히는 실린더헤드에 형성된 워터자켓을 이용하여 인젝터설치부의 지지력이 보강될 수 있도록 구성함에 따라 연소실의 폭발압력에 의해 상기 인젝터설치부가 쉽게 변형되면서 실린더헤드의 내구성이 저하되던 문제점을 효과적으로 해결할 수 있도록 한 자동차용 실린더헤드에 관한 것이다.The present invention relates to a cylinder head of an internal combustion engine for automobiles, and more particularly, the injector mounting portion is easily deformed by the explosion pressure of the combustion chamber as the bearing force of the injector mounting portion can be reinforced using a water jacket formed on the cylinder head. While it relates to a cylinder head for a vehicle that can effectively solve the problem that the durability of the cylinder head is lowered.

일반적으로 엔진은 실린더블럭과 실린더헤드로 구분할 수 있으며, 상기 실린 더블럭은 피스톤이 내부에서 상하왕복되면서 혼합기를 연소시키는 방으로서 강도나 내열성이 우수하며, 재질은 주철이 많이 쓰이지만 최근에는 알루미늄 합금도 많이 사용되고 있다.In general, an engine can be classified into a cylinder block and a cylinder head. The double block is a chamber for burning a mixer as the piston reciprocates up and down inside, and has excellent strength and heat resistance. Also used a lot.

그리고 실린더헤드는 상기 실린더블럭의 상부에 설치되며, 상기 실린더블럭과 일체로 연소실을 형성하는 외에 흡입, 배기통로를 개폐하는 밸브기구가 결합되어 있고, 인젝터가 설치되는 인젝터설치부와, 엔진오일이 통과하는 오일통로와, 냉각수가 통과하는 워터자켓과, 연소실에 불꽃을 튀겨주는 스파크플러그도 장착되어 있다.In addition, the cylinder head is installed on the upper part of the cylinder block, and in addition to forming a combustion chamber integrally with the cylinder block, a valve mechanism for opening and closing the intake and exhaust passages is coupled, and an injector installation unit in which an injector is installed, and an engine oil It is also equipped with an oil passage through, a water jacket through which cooling water passes, and a spark plug that splashes sparks in the combustion chamber.

한편, 도 1 은 종래 실린더헤드의 구성을 도시한 요부 단면도로서, 중앙에는 연소실을 향하여 인젝터가 설치되도록 인젝터설치부(20)가 형성되어 있고, 상기 인젝터설치부(20)를 중심으로 양측에는 엔진오일이 이동되는 오일통로(40)와, 냉각수가 이동되는 워터자켓(30)이 대향된 상태로 상부와 하부에 각각 형성되어 있다.On the other hand, Figure 1 is a sectional view showing the structure of the conventional cylinder head, the injector mounting portion 20 is formed in the center so that the injector is installed toward the combustion chamber, the engine on both sides around the injector mounting portion 20 The oil passage 40 through which the oil moves and the water jacket 30 through which the coolant moves are formed in the upper and lower portions, respectively.

그런데 상기 실린더헤드(10)에서 내구성에 가장 큰 영향을 미치는 부위는 연소실내로 연료를 분사하기 위해 인젝터가 설치되는 인젝터설치부(20)인데, 이는 연소실에 폭발압력이 발생할 때마다 그 영향에 의해 인젝터설치부(20)의 주변이 상,하,좌,우로 변형되면서 실린더헤드(10)의 피로파괴를 유도하게 됨에 따라 상기 인젝터설치부(20)의 변형은 실린더헤드(10)의 내구성을 저하시키는 원인이 되었다.However, the most influential part in the durability of the cylinder head 10 is an injector installation unit 20 in which an injector is installed to inject fuel into the combustion chamber, which is caused by the influence of an explosion pressure in the combustion chamber every time. As the periphery of the injector mounting portion 20 is deformed up, down, left, and right to induce fatigue destruction of the cylinder head 10, the deformation of the injector mounting portion 20 lowers the durability of the cylinder head 10. It was a cause.

따라서 본 발명의 목적은 상기와 같은 문제점을 해결하기 위한 것으로서, 연 소실의 폭발압력의 영향을 받는 실린더헤드의 인젝터설치부가 워터자켓의 구조변경에 의해 보강될 수 있도록 구성함에 따라 실린더헤드의 전체적인 내구성이 더욱 향상될 수 있도록 한 자동차용 실린더헤드를 제공하는데 있다.Therefore, an object of the present invention is to solve the above problems, the overall durability of the cylinder head as the injector installation of the cylinder head affected by the explosion pressure of the combustion chamber is configured to be reinforced by the structural change of the water jacket It is to provide a cylinder head for an automobile so that this can be further improved.

이와 같은 본 발명의 목적은 실린더헤드의 인젝터설치부를 중심으로 양쪽에 대향되게 형성되며, 실린더헤드의 길이방향을 따라 실린더헤드와 일체로 형성되는 워터자켓을 구성함에 있어서, The object of the present invention as described above is formed opposite to both sides of the injector mounting portion of the cylinder head, and in forming a water jacket integrally formed with the cylinder head along the longitudinal direction of the cylinder head,

상기 워터자켓의 중앙부에 실린더헤드의 길이방향을 따라 상기 실린더헤드와 일체인 격벽을 횡방향으로 형성하여, 상기 격벽에 의해 워터자켓이 양분되도록 구성하므로서 달성되는 것이다.It is achieved by forming a partition wall integral with the cylinder head in the transverse direction along the longitudinal direction of the cylinder head in the central portion of the water jacket, so that the water jacket is divided by the partition wall.

이러한 본 발명은 인젝터설치부와 근접되어 설치된 워터자켓에 격벽이 형성되면서, 상기 격벽으로 인하여 인젝터설치부의 지지력이 더욱 향상됨에 따라 연소실의 폭발압력에 의해 상기 인젝터설치부가 쉽게 변형되면서 실린더헤드의 내구성이 저하되던 문제점을 효과적으로 해결할 수 있으므로 상기 목적을 달성할 수 있는 것이다.In the present invention, as the partition is formed in the water jacket installed in close proximity to the injector installation portion, the injector installation portion is easily deformed by the explosion pressure of the combustion chamber as the support force of the injector installation portion is further improved due to the partition wall durability of the cylinder head It is possible to achieve the above object because it can effectively solve the problem that was lowered.

이하, 본 발명의 특징을 효과적으로 달성할 수 있는 바람직한 실시 예로서 그 기술구성 및 작용효과를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, with reference to the accompanying drawings, the technical configuration and operational effects as a preferred embodiment that can effectively achieve the features of the present invention will be described.

즉, 도 2 은 본 발명에 따른 실린더헤드의 요부 사시도이고, 도 3 은 본 발명에 따른 실린더헤드의 요부 단면도이다.That is, Fig. 2 is a perspective view of the main part of the cylinder head according to the present invention, and Fig. 3 is a sectional view of the main part of the cylinder head according to the present invention.

이에 예시한 바와 같이 본 발명은 실린더헤드(100)의 인젝터설치부(200)를 중심으로 양쪽에 대향되게 형성되며, 실린더헤드(100)의 길이방향을 따라 형성되는 워터자켓(300)을 구성함에 있어서, As exemplarily illustrated in the present invention, the injector mounting portion 200 of the cylinder head 100 is formed to face each other, and the water jacket 300 is formed along the longitudinal direction of the cylinder head 100. In

상기 워터자켓(300)의 중앙부에 실린더헤드(100)의 길이방향을 따라 실린더헤드(100)와 일체인 격벽(110)을 형성하여, 상기 격벽(110)에 의해 워터자켓(300)이 상하로 양분되도록 구성한 것을 특징으로 하는 것이다.A partition wall 110 integral with the cylinder head 100 is formed along the longitudinal direction of the cylinder head 100 at the center of the water jacket 300, so that the water jacket 300 is moved up and down by the partition wall 110. It is characterized in that configured to be bisected.

도면중 미설명 부호(400)은 엔진오일이 순환되는 오일통로이다.In the figure, reference numeral 400 is an oil passage through which engine oil is circulated.

이러한 본 발명은 실린더헤드(100)의 내부의 인젝터설치부(200)가 연소실의 폭발압력에 의하여 쉽게 변형되면서 실린더헤드(100)의 전체적인 내구성이 저하되던 문제점을 해결하기 위한 수단으로서, 상기 인젝터설치부(200) 양쪽에 위치한 워터자켓(300)의 중앙부에 실린더헤드(100)와 일체인 격벽(110)을 횡방향으로 형성함에 따라 상기 격벽(110)에 의해 인젝터설치부(200)가 효과적으로 지지될 수 있어 연소실의 폭발압력으로 인하여 인젝터설치부(200)가 쉽게 변형되던 문제점이 해결되면서 실린더헤드(100)의 내구성이 더욱 향상될 수 있는 것이다.The present invention as a means for solving the problem that the overall durability of the cylinder head 100 is lowered while the injector mounting portion 200 inside the cylinder head 100 is easily deformed by the explosion pressure of the combustion chamber, the injector installation The injector mounting portion 200 is effectively supported by the partition wall 110 by forming the partition wall 110 integral with the cylinder head 100 at the center of the water jacket 300 located at both sides of the part 200 in the lateral direction. The durability of the cylinder head 100 may be further improved while solving the problem that the injector installation part 200 is easily deformed due to the explosion pressure of the combustion chamber.

한편, 도 2 는 본 발명에 따른 실린더헤드를 예시한 것으로서, 상기 실린더헤드(100)의 단면을 보면 중앙에는 실린더헤드(100)의 하부에 위치한 연소실을 향해 인젝터가 설치될 수 있도록 인젝터설치부(200)가 형성되며, 상기 인젝터설치부(200)를 중심으로 배기쪽과 흡기쪽인 양쪽으로는 엔진오일이 순환되는 오일통로(400) 및 냉각수가 순환되는 워터자켓(300)이 실린더헤드(100)의 길이방향을 따라 형성되어 있다.On the other hand, Figure 2 illustrates the cylinder head according to the present invention, looking at the cross section of the cylinder head 100 in the injector installation unit so that the injector can be installed toward the combustion chamber located in the lower portion of the cylinder head 100 in the center ( 200 is formed, the oil passage 400 through which the engine oil is circulated and the water jacket 300 through which the coolant is circulated to both the exhaust side and the intake side around the injector installation unit 200. It is formed along the longitudinal direction of ().

여기서 본 발명의 특징은 상기 워터자켓(300)의 형상을 개선하여 상기 인젝터설치부(200)의 지지력이 더욱 향상될 수 있도록 한 것이다.The feature of the present invention is to improve the shape of the water jacket 300 so that the bearing capacity of the injector installation unit 200 can be further improved.

즉, 실린더헤드(100)의 길이방향으로 따라 형성되어 냉각수가 순환되는 워터자켓(300)을 형성하되, 상기 워터자켓(300)의 중앙부위에 실린더헤드(100)와 일체인 격벽(110)을 실린더헤드(100)의 길이방향을 따라 형성하므로서, 상기 워터자켓(300)은 격벽(110)에 의해 상하의 두부분으로 나뉘어지게 되는 것이다.That is, the water jacket 300 is formed along the longitudinal direction of the cylinder head 100 to circulate the coolant, and the partition wall 110 integrated with the cylinder head 100 is formed at the central portion of the water jacket 300. By forming along the longitudinal direction of the cylinder head 100, the water jacket 300 is divided into two parts of the top and bottom by the partition wall (110).

따라서 상기 격벽(110)으로 인하여 인젝터설치부(200)의 강성이 더욱 커지게 되면서 연소실의 폭발압력에 의해 상기 인젝터설치부(200)가 상,하,좌,우방향으로 변형되던 현상을 최소화시킬 수 있는 것이다.Therefore, the rigidity of the injector mounting unit 200 becomes greater due to the partition wall 110, thereby minimizing the phenomenon that the injector mounting unit 200 is deformed in the up, down, left, and right directions by the explosion pressure of the combustion chamber. It can be.

아울러 상기와 같이 격벽(110)을 이용하여 워터자켓(300)을 양분함에 있어서, 도 3 에 예시된 워터자켓(300)의 단면형상을 기준으로 보았을 때 도면에는 예시되어 있지 않지만In addition, in dividing the water jacket 300 by using the partition wall 110 as described above, when not seen based on the cross-sectional shape of the water jacket 300 illustrated in FIG.

상기 격벽(110)을 워터자켓(300)의 중앙부위에 종방향으로 형성하는 것은 바람직하지 못하며, 격벽(110)을 워터자켓(300)의 중앙부위에서 횡방향으로 형성하는 것이 바람직 한 것이다.It is not preferable to form the partition wall 110 in the central portion of the water jacket 300 in the longitudinal direction, it is preferable to form the partition wall 110 in the transverse direction at the center portion of the water jacket (300).

또한 도면에는 예시되지 않았지만 상기 격벽(110)을 워터자켓(300)의 중앙부위에 횡방향으로 형성하되 인젝터설치부(200)와 직각이 되도록 형성할 수도 있는 것이며, 역시 도면에는 예시되지 않았지만 상기 격벽(110)을 워터자켓(300)의 중앙부위에 횡방향으로 형성하되 비스듬하게 경사진 형태로 형성할 수도 있는 것이다.In addition, although not illustrated in the drawing, the partition wall 110 may be formed in the center portion of the water jacket 300 in a lateral direction, but may be formed to be perpendicular to the injector installation unit 200, but the partition wall is not illustrated in the drawing. 110 may be formed in the horizontal portion in the central portion of the water jacket 300, but may be formed in an obliquely inclined form.

그리고 도 3 에서와 같이 격벽(110)을 워터자켓(300)의 중앙부위에 횡방향으 로 형성하되 상기 격벽(110)을 경사지면서 만곡진 형태로 구성하게 되면 상기 격벽(110)이 연소실의 폭발압력에 의한 인젝터설치부(200)의 변형에 보다 효과적으로 대응할 수 있으므로 격벽(110)에 의한 인젝터설치부(200)의 보강효과를 극대화시킬 수 있는 것이다.In addition, as shown in FIG. 3, when the partition wall 110 is formed in the transverse direction at the central portion of the water jacket 300, the partition wall 110 is formed in a curved shape while inclining the partition wall 110 to explode in the combustion chamber. Since it can more effectively respond to the deformation of the injector mounting portion 200 by the pressure it is possible to maximize the reinforcing effect of the injector mounting portion 200 by the partition wall (110).

이상과 같이 본 발명의 바람직한 실시 예를 설명하였으나 본 발명은 다양한 변화와 변경 및 균등물을 사용할 수가 있으며, 상기 실시 예를 적절히 변형하여 동일하게 응용할 수 있음이 명확하다. 따라서 상기 기재 내용은 하기 특허청구범위의 한계에 의해 정해지는 본 발명의 범위를 한정하는 것은 아니다.As described above, the preferred embodiment of the present invention has been described, but the present invention may use various changes, modifications, and equivalents. Therefore, the above description does not limit the scope of the invention defined by the limitations of the following claims.

이상에서 상술한 바와 같이 본 발명은 실린더헤드에 형성되어 있는 인젝터설치부가 연소실의 폭발압력에 따라 쉽게 변형되면서 실린더헤드의 내구성을 저하시키는 문제점을 해결하기 위한 방법으로서, 인젝터설치부의 양쪽에 근접된 상태로 형성되어 있는 워터자켓의 중앙부에 실린더헤드와 일체인 격벽을 형성하므로서 상기 격벽에 의하여 인젝터설치부의 지지력이 더욱 커지게 됨에 따라 연소실의 폭발압력에 따라 인젝터설치부가 쉽게 변형되면서 결국 실린더헤드의 내구성이 저하되던 문제점을 효과적으로 방지할 수 있는 것이다.As described above, the present invention is a method for solving the problem of deteriorating the durability of the cylinder head while the injector mounting portion formed in the cylinder head is easily deformed according to the explosion pressure of the combustion chamber, and is in close proximity to both sides of the injector mounting portion. As the bulkhead is formed integrally with the cylinder head at the center of the water jacket, the support capacity of the injector mounting portion is increased by the partition wall, and the injector mounting portion is easily deformed according to the explosion pressure of the combustion chamber, resulting in the durability of the cylinder head. It is possible to effectively prevent the problem that was degraded.
