Abstract
본 발명은 디젤 엔진의 연료분무 테스트장치를 개시한다. 개시된 본 발명은, 디젤 엔진의 피스톤 상부에 끼워진 중공형의 확장 피스톤(1); 상기 확장 피스톤(1)의 중공부내에 끼워지고, 상부에 연소실을 구성하는 캐비티(210가 형성된 투명 피스톤(2); 상기 투명 피스톤(2)의 캐비티(21)와 함께 연소실을 구성하는 실린더 헤드(7)에 설치되고, 연료를 분사시키는 인젝터(3)의 하단과 소정의 거리로 이격배치되어 분사된 연료가 충돌되는 충돌 디스크(4); 상기 확장 피스톤(1)의 하부 실린더 내벽에 소정의 각도로 경사지게 설치된 수경; 상기 수경에 잡힌 연소실의 연료분무 상태를 촬영하도록, 실린더 측벽에 설치된 카메라; 및 상기 카메라에서 촬영된 사진에 촬영시점을 나타내기 위해 크랭크축의 각도를 측정하여 기록시키는 크랭크 각도 피스톤(1)의 캐비티(21)의 내벽 일측부에 측방에서 연소실의 연료분무상태를 관찰하기 위한 반사경(5)이 소정의 각도로 하향경사지게 설치되고, 상기 반사경(5)에서 하방으로 반사된 화면을 받는 또 다른 수경이 설치된 것을 특징으로 한다.The present invention discloses a fuel spray test apparatus for a diesel engine. The disclosed invention relates to a hollow expanding piston (1) fitted to an upper portion of a piston of a diesel engine; A transparent piston 2 fitted in a hollow portion of the expansion piston 1 and having a cavity 210 formed therein at an upper portion thereof and a cylinder head 21 constituting a combustion chamber together with the cavity 21 of the transparent piston 2 7, a collision disk 4 which is disposed at a predetermined distance from the lower end of the injector 3 for injecting fuel and in which the injected fuel is collided, a collision disk 4 which is provided in the lower cylinder inner wall of the expansion piston 1 at a predetermined angle A crank angle piston for measuring and recording the angle of a crankshaft to indicate a photographing time point on a photograph taken by the camera; and a crank angle piston for measuring the angle of the crankshaft A reflecting mirror 5 for observing the fuel spraying state of the combustion chamber is provided at a side of one side of the inner wall of the cavity 21 of the reflecting mirror 5 at a predetermined angle, It characterized in that the other rigs that receives the reflection screen downward are installed.
