Fuel injection control device

A fuel injection control device for executing multiple injection includes first means for determining the total injection quantity of fuel (Qtotal), second means for determining base injection quantities (QBsub) of each auxiliary injection, and third means which, when the sum (QBsubtotal) of base injection quantities (Qsub) of each of auxiliary injections is not larger than the value obtained by multiplying the total injection quantity (Qtotal) by a coefficient (K) (0 < K
