Embodiment Construction
[0036] The internal visualization of the engine requires a lighting device to provide sufficient brightness so that the movement process of the components in the engine cylinder, the formation process of the mixture gas, and the combustion state can be captured by image acquisition devices such as cameras or endoscopes. At present, optical single-cylinder engines usually use external LED lights for lighting, and high-speed cameras are installed vertically to record the process of spraying, ignition, and combustion in the cylinder. However, because the transparent glass cylinder liner is cylindrical, the external light source will cause severe The reflections seriously affect the imaging quality of high-speed cameras. The multi-cylinder engine uses an endoscope to record the working process in the cylinder, and installs the optical fiber lighting system and the endoscope shooting system after drilling holes in the cylinder head. Large attenuation will easily lead to insufficien...
