Abstract
A system for controlling a compression ignition engine includes: a speed obtaining section which obtains an engine speed; and an injection amount setting section which sets, in a start period after the start of cranking, a fuel injection amount to be injected by injectors in next and subsequent cycles. If an engine speed achieved by combustion in an (n−1)-th cycle is higher than or equal to a determination threshold value and lower than a lower limit of the resonance range, the injection amount setting section sets the fuel injection amount for the n-th cycle to a jump-over injection amount, and sets the fuel injection amount for the (n+1)-th cycle to a resonance induction reducing amount, which is smaller than the jump-over injection amount.
