Abstract (en)

[origin: EP2428668A2] Fuel injection control apparatus for a diesel engine having a plurality of cylinders, the fuel injection control apparatus comprising a calculation unit that calculates a fuel injection amount for each cylinder, and a storage unit (16) that has a storage area corresponding to each cylinder and stores in a corresponding storage area a calculation result generated by the calculation unit. When a low rotation speed switches to a high rotation speed, a calculation result Q# 2 , which was used to inject fuel into a cylinder #2 prior to the switch, is used to inject fuel into a cylinder #3, which is subjected to fuel injection following the cylinder #2. A calculation result Q# 1 can be used by an ECU (8) to inject fuel into the cylinder #2 immediately after the aforesaid switch.
