An internal combustion engine control device having exhaust gas sensors provided before and after a catalyst or after the catalyst, a processor for signals from the exhaust gas sensors, and an electronic controller. The electronic control is arranged for controlling the amount of fuel to be fed to the internal combustion engine, ignition timing, the amount of secondary air for reducing the emission, the amount of EGR (exhaust gas recirculation), electrically heated catalyst, assisted air flow, and gas flow in the cylinders or intake exhaust valve timing of internal combustion engine. Using the controller the conversion rate (degree of activation) is detected with high precision from the processed sensor signals, and the emission is most suitably controlled to be reduce according to the degree of activation in order to meet both present stringent exhaust gas regulations and those which are predicted for the future.
