Abstract
A control system includes a processor for controlling an internal combustion engine having a temperature region, wherein a change of ignition delay time accompanying a rise in a cylinder temperature when the cylinder temperature is in the temperature region is smaller than when the cylinder temperature is out of the temperature region. When a self ignition timing of secondary fuel is earlier than a self ignition timing of primary fuel due to the secondary fuel being injected at a crank angle at which the cylinder temperature is higher than the temperature region, the processor controls a ratio of the secondary fuel to be lower than when the self ignition timing of the secondary fuel is later than the self ignition timing of the primary fuel due to the secondary fuel being injected at a crank angle at which the cylinder temperature is within the temperature region.
