PURPOSE:To compensate for the fall in combustibility, by utilizing the control signal of an air fuel ratio compensation circuit as an alcohol concentration detection signal and providing a compensation circuit to perform the compensatory regulation of a combustion state control means when the concentration of alcohol has exceeded a limit. CONSTITUTION:A compensation circuit 22 is provided in an ignition time controller 10. When the air fuel ratio control signal of an air fuel ratio compensation circuit 8 has exceeded the higher limit for the air fuel ratio, namely, when the concentration of alcohol has exceded a set level, the circuit 22 sends out a compensation signal for advancing the time of ignition. This results in compensating for the fall in combustion velocity which is caused by the rise in the concentration of alcohol. Good combustion is thus ensured. |
