Engine control apparatus

Engine control apparatus includes: engine including injector configured to inject fuel into combustion chamber and ignition plug configured to ignite air-fuel mixture of fuel and air in combustion chamber; temperature sensor configured to detect temperature of engine; and controller configured to control injector based on temperature detected by temperature sensor. Fuel injected by injector is at least one of gasoline fuel and reformed fuel obtained by reforming part of gasoline fuel into peroxide. Controller controls injector so as to inject gasoline fuel at first target injection timing when temperature detected by temperature sensor exceeds predetermined temperature at starting of engine, and controls injector so as to inject reformed fuel at second target injection timing retarded from first target injection timing when temperature detected by temperature sensor is equal to or lower than predetermined temperature.
