METHOD AND DEVICE FOR CONTROLLING COMPRESSION IGNITION ENGINE

A system for controlling a compression ignition engine includes: a speed obtaining section (102) which detects or estimates an engine speed achieved by combustion in an n-th cycle; and an injection amount setting section (105) which sets, in a start period after the start of cranking, a fuel injecti...

Beschreibung
Zusammenfassung:	A system for controlling a compression ignition engine includes: a speed obtaining section (102) which detects or estimates an engine speed achieved by combustion in an n-th cycle; and an injection amount setting section (105) which sets, in a start period after the start of cranking, a fuel injection amount to be injected by injectors (18) in an (n + 1)-th cycle. If the engine speed achieved by the combustion in the n-th cycle falls in the resonance range (Br), the injection amount setting section (105) sets the fuel injection amount for an (n + 1)-th cycle to be larger than the fuel injection amount injected when the engine speed is higher than or equal to an upper limit (R2) of the resonance range (Br).
