Description
본 고안은 엔진의 연소실내의 화염전파 특성 관찰용의 광섬유 가스켓에 관한 것이다.The present invention relates to an optical fiber gasket for observing flame propagation characteristics in a combustion chamber of an engine.
엔진의 연소실의 설계에 있어서 노킹 발생을 방지하고 강력한 폭발력을 얻기 위해서는 연소실 내에서 진행되는 화염전파 특성을 파악하는 것이 중요하다.In the design of the combustion chamber of the engine, it is important to understand the flame propagation characteristics in the combustion chamber in order to prevent knocking and to obtain a strong explosive force.
이를 위해 종래의 경우 연소실 내부 상황을 관찰할 수 있도록 여러가지 방식의 화염 가시화 장치가 사용되고 있다.To this end, various types of flame visualization devices have been used in the related art so that the situation inside the combustion chamber can be observed.
통상 사용되고 있는 화염 가시화 장치로는 피스톤에 유리창 또는 렌즈를 설치하고 광학 기구를 통해 외부로 반사되는 영상을 통해 연소실의 내부 상황을 관찰하는 방법이 많이 사용되고 있다.As a flame visualization apparatus, a glass window or a lens is installed on a piston, and a method of observing an internal situation of a combustion chamber through an image reflected to the outside through an optical apparatus is widely used.
그러나 상기한 방식은 시각적 확인 방식이어서 노련한 숙련자가 아니면 연소실 내부 상황을 분석하는 것이 곤란하며 장치의 구조가 복잡해지는 문제점이 있게된다.However, the above-described method is a visual confirmation method, so it is difficult to analyze the internal situation of the combustion chamber unless the skilled person is skilled and there is a problem in that the structure of the device becomes complicated.
이에 본 고안은 상기한 문제점을 감안하여 제안된 것으로서 그의 목적으로 하는 바는 연소실 내의 화염전파 특성에 대한 정보를 전기적으로 검출하는 데 사용될 수 있는 광섬유 가스켓을 제공하는데 있다.Accordingly, the present invention has been proposed in view of the above problems, and an object thereof is to provide an optical fiber gasket that can be used to electrically detect information on flame propagation characteristics in a combustion chamber.
상기한 목적을 달성하기 위하여 본 고안은The present invention to achieve the above object is
실린더 헤드와 실린더 블록 사이에 가스 누설 방지를 위해 삽입되는 가스켓에 있어서;A gasket inserted between the cylinder head and the cylinder block to prevent gas leakage;
상기 가스켓에는 외부로부터 연소실에 위치하게 되는 보어부까지 연소실의 각 위치에서 일어나는 화염전파 특성에 관한 정보를 검출하기 위한 광섬유가 매설되어 있는 것을 특징으로 한다.The gasket is characterized in that the optical fiber for detecting information on the flame propagation characteristics occurring at each position of the combustion chamber from the outside to the bore portion located in the combustion chamber.

이하 본 고안의 구성과 작용을 첨부한 도면을 참조하여 설명한다.Hereinafter, with reference to the accompanying drawings the configuration and operation of the present invention.
도 1 은 본 고안에 의한 연소실의 화연전파 측정용의 광섬유 가스켓을 나타내는 도면이며 도 2 는 동상 광섬유 가스켓이 장착된 엔진을 나타내는 도면으로 도면중 부호 1 은 실린더 헤드(2)를 실린더 블록(3)에 체결시 가스 누설을 방지하기 위해 개재되는 가스켓으로서 가스켓(1)의 표면에는 방사상으로 홈을 파고 복수개의 광섬유(4)가 매설되어 있다.1 is a view showing an optical fiber gasket for measuring the flame propagation of the combustion chamber according to the present invention, Figure 2 is a view showing an engine equipped with an in-phase optical fiber gasket, in which 1 is a cylinder head (3) cylinder head (3) As a gasket interposed in order to prevent gas leakage when fastened to the gasket, grooves are radially dug on the surface of the gasket 1 and a plurality of optical fibers 4 are embedded.
상기 광섬유 가스켓(1)의 광섬유(4)들은 별도의 측정장치에 접속되어져 연소실 보어부(5)에 드러난 끝단이 연소가 진행되면 연소실(6)의 각 부분에서의 화염전파 특성, 예를들어 스파크 플러그(7)가 점화되고 화염전파에 의해 혼합기가 점화되면 온도가 상승하게 되므로 그 온도를 광섬유(4)가 감지하여 이를 전기적 신호로 전달하므로써 화염전파 도달시간이나 온도등의 정보에 기초하여 화염전파 특성을 관찰하게 되는 것이다.The optical fibers 4 of the optical fiber gasket 1 are connected to a separate measuring device so that when the end exposed to the combustion chamber bore 5 is burned, flame propagation characteristics, for example, sparks, in each part of the combustion chamber 6 are generated. When the plug 7 is ignited and the mixer is ignited by flame propagation, the temperature rises. Therefore, the optical fiber 4 detects the temperature and transmits it as an electrical signal, thereby transmitting the flame propagation based on information such as the flame propagation time or temperature. Observe the characteristics.
이와같이 스틸재 가스켓에 홈을 파고 광섬유를 매설하므로써 초기 화연전파 특성을 관찰할 수 있게 된다.In this way, by indenting the steel gasket and embedding the optical fiber, it is possible to observe the characteristics of the initial flame propagation.
이상과 같은 본 고안에 의하면 가스 누설 방지를 위해 실린더 헤드와 실린더 블록 사이에 개재되는 가스켓에 연소실 내부의 화염전파 특성을 감지하여 분석장치로 신호 전송할 수 있는 광섬유를 매설하는 것에 의해서 극히 간단한 구조 변경으로 초기 화염 전파에 대한 정보를 얻는 것이 가능하므로써 엔진 개발 비용을 절감하는 것이 가능하게 된다.According to the present invention as described above, in order to prevent gas leakage, a gasket interposed between the cylinder head and the cylinder block detects flame propagation characteristics inside the combustion chamber and embeds an optical fiber that can transmit a signal to an analysis device. By being able to obtain information about the initial flame propagation, it is possible to reduce engine development costs.
