Description

연소실 관찰장치의 가시화창 파손 방지장치Visible window breakage prevention device of combustion chamber observing device

본 고안은 엔진의 노킹 발생 위치를 확인하기 위한 연소실의 연소상황 관찰장치에 관한 것이다.The present invention relates to a combustion situation observation device of the combustion chamber for confirming the knocking position of the engine.

일반적으로 엔진의 경우 노킹 발생위치가 연소실내의 흡기 영역에서 발생하게 되는데 정확한 노킹발생 지점을 확인하기 위하여 석영재질로 된 가시화창(quartz)을 통해 외부에서 연소실을 들여다 보는 방법이 이용되고 있다.In general, in the case of an engine, a knocking position is generated at an intake area of a combustion chamber. In order to identify an accurate knocking point, a method of looking at the combustion chamber from the outside through a quartz window made of quartz is used.

그러나 제2도에 도시한 것과 같이 가시화창(20)이 테이퍼 형상일 때 관찰 가능부분이 협소하였으며 노킹 및 정상연소시에 피스톤(10)이 열팽창을 하므로서 클램프(50)의 조임력에 의해 상기 가시화창(20)이 상부로 이동하고, 이때 팽창했던 피스톤(10)이 수축되면서 가시화창(20)은 수축력을 견디지 못하여 깨지는 경우가 발생하므로 노킹 발생 지점을 찾지 못할 뿐만 아니라 비용과 작업시간에 능률적이지 못한 문제점이 지적되고 있다.However, as shown in FIG. 2, the visible part 20 is tapered in view of the tapered shape, and the visualizing window is tightened by the clamping force of the clamp 50 due to thermal expansion of the piston 10 during knocking and normal combustion. (20) moves to the upper portion, the expansion of the piston (10) at this time as the visible window 20 is not broken because it can not withstand the contraction force is broken, not only find the point of knocking, but also inefficient cost and working time The problem is pointed out.

이에 본 고안은 상기한 문제점을 개선시키기 위하여 가시화창의 파손을 방지하며 정확한 노킹 발생 지점을 찾도록 하는데 그 목적이 있다.In this regard, the present invention aims to prevent the breakage of the visible window and to find an accurate knocking point in order to improve the above problems.

상기한 목적을 달성하기 위한 수단으로 본 고안은, 실린더내에 내장되어 연소실의 상황을 투시하며 빛의 경로를 반사하여 변경하는 미러와, 상기 미러에 의해 반사되는 영상을 촬영하여 확인하는 카메라로 구성되는 연소실 관찰장치에 있어서, 상기 피스톤의 내측에 삽입되어 상단부와 하단부가 쳄버 처리된 원기둥 형상의 가시화창과, 상기 가시화창의 상하측에 결합되어 피스톤의 팽창 및 진동을 방지하는 고정구로 구성된을 특징으로 한다.As a means for achieving the above object, the present invention comprises a mirror that is embedded in the cylinder to see the situation of the combustion chamber and reflects and changes the path of the light, and a camera for photographing and confirming the image reflected by the mirror In the combustion chamber observing apparatus, it is characterized in that the cylinder is inserted into the interior of the cylinder and the upper end and the lower end of the cylinder-shaped visualized window, and coupled to the upper and lower sides of the visualization window to prevent expansion and vibration of the piston.

이를 첨부한 실시예 도면을 참조하여 보다 상세하게 설명하면, 제1도는 본 발명에 의한 연소실 관찰장치의 구성을 보인 일부 확대도이고 부호 1 은 피스톤, 부호 2 는 가시화창이다.Referring to this in more detail with reference to the accompanying drawings, Figure 1 is a partially enlarged view showing the configuration of the combustion chamber observation apparatus according to the present invention, 1 is a piston, 2 is a visualization window.

상기 연소실내에는 피스톤(1)에 삽입되어 빛을 투과하는 석영재질로 형성되며, 상하측에 쳄버 처리된 가시화창(2)이 삽입된다. 상기 가시화창(2)의 상하측을 피스톤(1)의 팽창 및 진동으로부터 보호되도록 결합되는 고정구(3)가 구성된다.In the combustion chamber is formed of a quartz material which is inserted into the piston (1) and transmits light, and a chamber (2) is provided with a chamber treatment on the upper and lower sides. A fastener 3 is configured to couple the upper and lower sides of the visualization window 2 to be protected from expansion and vibration of the piston 1.

상기 고정구(3)의 저면으로는 가시화창(2)의 진동에 따른 충격을 완화시키는 연질의 와셔(4)가 끼워지고, 상기 피스톤(1)의 하단에는 클램프(5)를 나사조립하여 피스톤 내부의 부품이 이탈되지 않도록 하였다.A soft washer 4 is fitted into the bottom of the fixture 3 to alleviate the impact caused by the vibration of the visualization window 2, and the clamp 5 is screwed into the lower end of the piston 1 to form the inside of the piston. The parts of the are not to be separated.

상기와 같이 구성된 본 고안은 연소실의 폭발에 의해 피스톤(1)은 고온상태가 되면서 열팽창을 하게 되는바 피스톤(1)내에서는 진동 및 충격이 가시화창(2)으로 전해지게 된다.According to the present invention configured as described above, the piston 1 is thermally expanded due to the explosion of the combustion chamber, and the vibration and shock are transmitted to the visualization window 2 in the piston 1.

이때 상기 피스톤(1)의 내부에 결합되어 가시화창(2)의 상하단으로 구성된 고정구(3)는 원기둥 형상의 가시화창(2)을 상부로 밀어내지 않고 특히 취약한 상부와 하부를 감싸면서 보호하고, 고정구(4)의 하부에 결합된 와셔는 고정구의 진동에 따른 충격을 완화하므로 상하측의 취약부 파손부담이 줄어들며 피스톤(1)이 냉각되면서 가시화창(2)으로 수축력이 전달되기 전에 고정구(3)의 완화로 인하여 수축력을 견딜 수 있게 되는 것이다.At this time, the fastener (3) is coupled to the inside of the piston (1) consisting of the upper and lower ends of the visualization window (2) protects by wrapping the particularly weak upper and lower portions without pushing the cylindrical visualization window (2) upwards, The washer coupled to the lower part of the fixture 4 mitigates the impact caused by the vibration of the fixture, thereby reducing the burden of vulnerable parts on the upper and lower sides, and while the piston 1 is cooled, the fixture 3 before the contraction force is transmitted to the visible window 2. Due to the relaxation of the ability to withstand shrinkage.

이상과 같은 연소상황 관찰장치의 가시화창 파손방지 장치에 의하면 피스톤의 온도가 상승되더라도 피스톤에 삽입되는 가시화창을 고정구가 보호하여 파손을 방지하므로 연소상황 관찰이 용이하고 작업시간 및 가시화창의 파손에 따른 비용절감에 효과적인 고안인 것이다.According to the visualizing window breakage prevention device of the combustion situation observation device as described above, even if the temperature of the piston rises, the fixing tool protects the visualized window inserted into the piston to prevent breakage. It is an effective design for cost reduction.
