PURPOSE:To enable control of a combustion state without the occurrence of a delay throughout a wide range, by a method wherein by means of a signal inputted from a combustion state detecting means, the control factor of a combustion state is controlled. CONSTITUTION:Specified wavelength energy of a combustion flame is detected as a combustion state in a combustion chamber 4 by means of a light energy sensor 26 to input the result to a control circuit 38. Fuel is injected so that an air-fuel ratio is regulated to a given value by controlling the motion of an injection valve 6 so that combustion is brought into a target state, and sparks are flied to an ignition plug 8 so that an ignition timing is regulated to a given value by feedback-controlling the feed to an ignition coil 40. This constitution enables provision of a desired combustion state responding to the running state of an internal combustion engine 2. As noted above, on airfuel ratio is directly and instantaneously detected as a combustion state by means of the light energy 26. This detecting signal is inputted to a control circuit 35, and by controlling an air-fuel ratio and an ignition timing, a combustion state is controllable without the occurrence of a delay throughout a wide range.
