PURPOSE:To maintain a proper fuel injection time or ignition timing, by a method wherein, on the particular conditions of the throttle opening and an intake air amount of an internal-combustion engine, a means is provided for computing a fuel injection amount and/or an ignition timing by the use of a detecting value of an intake air amount. CONSTITUTION:An airflow meter 3 measures an intake air amount of an internal-combustion engine 1, and an output signal is fed to a control device 50. A throttle sensor 5 is provided for detecting the opening of a throttle valve 4. The fuel injection time of a fuel injection valve 9 is decided by a control device 50. An ignitor 12, determining the ignition timing of an ignition plug 11, is driven by a control device 50. This constitution enables maintenance of a proper fuel injection time or ignition timing.
