Visualization window of combustion chamber observation device Breakage prevention device

摘要

The subject innovation relates to a combustion state of the furnace observation apparatus to determine whether knocking occurred in the engine.; That the present design as a means for achieving the above object, is built in the cylinder perspective of the combustion chamber conditions and change the path of light reflected by the mirror; Camera and confirming by photographing the image reflected by the mirror; in the furnace observation apparatus consisting of the piston (1) is inserted in the inner top and bottom sections are made visible in the chamber processed column-shaped window (2) of the .; It is characterized in the configuration of; the visualization is coupled to the upper and lower sides of the window (2), the fastener (3) for preventing expansion and vibration of the piston.
