본 발명은 자동차에 사용되는 디젤엔진의 연소실에 관한 것으로, 특히 상반부재와 하반부재의 결합되는 부위에 밀폐공간을 형성함으로서, 결합시 금속재질로 이루어진 하반부재의 용적을 적게하여, 상반부재와 상반부재와의 열팽창차이를 감소하고, 이에따라 연소실의 내구성이 향상될 수 있도록 한 밀폐공간이 형성된 자동차 디젤엔진의 연소실에 관한 것이다.The present invention relates to a combustion chamber of a diesel engine used in an automobile, and in particular, by forming a closed space at a portion where the upper half member and the lower half member are coupled, to reduce the volume of the lower half member made of a metal material at the time of joining, the upper half member and the upper half member The present invention relates to a combustion chamber of an automotive diesel engine in which an enclosed space is formed so as to reduce a difference in thermal expansion with a member and thereby improve durability of the combustion chamber.
종래 디젤엔진의 연소실은 제1도에 도시되는 바와 같이, 연소실을 이루는 상반부재(1)는 세라믹 재질로 이루어져 있고, 하반부재(4)는 금속재로 이루어져 있다.As shown in FIG. 1, the combustion chamber of the conventional diesel engine is made of a ceramic material, and the lower half member 4 is made of a metal material.
상기 상반부재(1)의 하부에는 이빨부(2)가 형성되어 있고, 그 주위로 섬유질(3)이 둘러 쌓여있으며, 하반부재(4)는 상기 상반부재(1)의 이빨부(2)와 대응한 구조를 가지며 결합될 수 있도록 이빨부(5)가 상부에 형성되어 있고, 그 주위도 섬유질(6)이 둘러 쌓여있다.A lower portion of the upper half member 1 has a tooth portion 2 formed therein, and a fiber 3 is enclosed around the lower half member 4, and the lower half member 4 has a tooth portion 2 of the upper half member 1. Teeth 5 are formed on the upper part so as to have a corresponding structure and can be combined, and the fiber 6 is also surrounded.
이러한, 종래 디젤엔진의 상반부재(1)와 하반부재(4)는 별도의 밀폐공간이 형성되어 있지 않기 때문에, 결합시 금속재질로 이루어진 하반부재(4)의 용적이 커지게 되고, 이에따라 상반부재(1)와 하반부재(4)에서 열팽창 차이가 커져 쉽게 파손되고, 내구성이 저하되어 수명이 단축되는 문제점이 발생되었다.Since the upper half member 1 and the lower half member 4 of the conventional diesel engine do not have a separate sealed space, the volume of the lower half member 4 made of a metal material is increased when the upper half member 1 and the lower half member 4 are joined. The difference in thermal expansion in (1) and the lower half member 4 is easily broken, and the durability is lowered, resulting in a problem of shortening the life.
따라서, 본 발명의 목적은 상기와 같은 종래의 문제점을 해소하기 위해 안출한 것으로, 상반부재와 하반부재의 결합되는 부위에 밀폐공간을 형성함으로서, 결합시 금속재질로 이루어진 하반부재의 용적을 적게하여, 상반부재와 상반부재와의 열팽창차이를 감소하고, 파손되는 것을 방지할 수 있도록 할뿐 아니라, 이에따라 연소실이 내구성을 향상하여 수명을 연장할 수 있도록 한 밀폐공간이 형성된 자동차 디젤엔진의 연소실을 제공하는데 있다.Accordingly, an object of the present invention is to devise to solve the conventional problems as described above, by forming a closed space at the portion of the upper half member and the lower half member to combine, to reduce the volume of the lower half member made of a metal material at the time of joining In addition, to reduce the thermal expansion difference between the upper half member and the upper half member and to prevent breakage, accordingly to provide a combustion chamber of the automotive diesel engine with a closed space formed to increase the durability by extending the combustion chamber durability It is.
이하 첨부된 도면에 의거하여 본 발명의 기술적 구성을 상세히 설명하면 다음과 같다.Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.
본 발명은 세라믹 재질로 이루어진 상반부재(10)와, 금속재로 이루어진 하반부재(20)로 이루어진 디젤엔진의 연소실에 있어서, 상기 상반부재(10)와 하반부재(20)의 결합되는 부위에 밀폐공간(21)을 형성하여, 열팽창차이를 저감함을 그 기술적 구성상의 기본 특징으로 한다.The present invention, in the combustion chamber of the diesel engine consisting of the upper half member 10 made of a ceramic material, the lower half member 20 made of a metal material, the closed space at the portion where the upper half member 10 and the lower half member 20 are coupled; (21) is formed and the thermal expansion difference is reduced as the basic feature on the technical constitution.
이와 같이 구성된 본 발명은 상반부재(10)와 하반부재(20)를 결합시키면, 결합되는 부위 즉, 상기 하반부재(20)에 형성된 밀폐공간(21)에 의하여, 금속재질로 이루어진 하반부재(20)의 용적이 작아지고, 이에따라 상반부재(10)와 하반부재(20)의 열팽창차이가 작아진다.According to the present invention configured as described above, when the upper half member 10 and the lower half member 20 are coupled to each other, the lower half member 20 made of a metal material is formed by a closed space 21 formed in the portion that is coupled to the lower half member 20. ) Volume becomes small, and accordingly, the thermal expansion difference of the upper half member 10 and the lower half member 20 becomes small.
이상에서 살펴본 바와같이, 본 발명은 상반부재와 하반부재의 결합되는 부위에 밀폐공간을 형성함으로서, 결합시 금속재질로 이루어진 하반부재의 용적을 적게하여, 상반부재와 상반부재와의 열팽창차이를 감소하고, 연소실이 파손되는 것을 방지할 수 있도록 한 것이다.As described above, the present invention forms a closed space at the portion where the upper half member and the lower half member are coupled to each other, thereby reducing the volume of the lower half member made of a metal material at the time of joining, thereby reducing the thermal expansion difference between the upper half member and the upper half member. It is to prevent the combustion chamber from being damaged.
또한, 연소실이 파손되는 것을 방지함으로서, 내구성이 향상되어 수명을 연장할 수 있는 등의 효과가 있는 것이다.In addition, by preventing the combustion chamber from being damaged, the durability is improved and the life can be extended.
