Abstract

An internal-combustion-engine control apparatus according to the present disclosure controls an internal combustion engine having

a main combustion chamber,a subsidiary combustion chamber,an ignition plug that is disposed in the subsidiary combustion chamber,an ignition coil connected with the ignition plug, andan orifice for connecting the subsidiary combustion chamber with the main combustion chamber and for injecting combustion gas in the subsidiary combustion chamber into the main combustion chamber; the internal-combustion-engine ignition apparatus includesan ignition control unit that controls energization of the ignition coil so that an ignition discharge for igniting a fuel-air mixture in the subsidiary combustion chamber is produced across the ignition plug, anda pressure-boosting control unit that controls energization of the ignition coil so that a pressure-boosting discharge for increasing a pressure of combustion gas in the subsidiary combustion chamber is produced across the ignition plug.
