PURPOSE:To externally detect a flame figure in a combustion chamber by air- tightly providing a seeing through window through which a flame figure is transmitted in the combustion chamber on the side of a penetrated hole and fixing an optical fiber on a side opposite to the combustion chamber on the above side. CONSTITUTION:A penetrated hole to externally propagate a flame figure generated in a combustion chamber 2 is formed on the partition wall 3 of the combustion chamber 2 of a reciprocating internal-combustion engine 1. A seeing through window 11 to pass the flame figure is air-tightly provided on the inside of the combustion chamber 2 on the side of a penetrated hole 4. An optical fiber 19A into which the flame figure passing through the seeing through window 11 is fed is fixed on the outside of the combustion chamber 2 on the side of the penetrated hole 4. The seeing through window 11 is formed into condensing lens type, and its focus serves as the plane of incidence for the light fiber. In addition, this plane is at least arranged farther from the outside of the partition wall located near by the combustion chamber. The flame figure in the combustion chamber can be therefore externally detected. |
