Zusammenfassung: | PROBLEM TO BE SOLVED: To improve a photoelectron measurement device uniformly detecting a previously defined measurement sector in a combustion chamber by means of a light receiving angle area of an optical sensor with a sensor edge part on the combustion chamber side arranged to form a plane substantially so as to lower a production cost and a measurement cost. SOLUTION: The sensor 7 is arranged in a cylindrical part 6 such as an ignition plug inserted into a combustion chamber 5 so that the end part 8 of the sensor 7 radially faces an outer circumference part 14 of the part 6. |
