Abstract
A control device for controlling an engine includes main-chamber injecting means () that supplies a main chamber () with fuel; sub-chamber injecting means () that supplies a sub chamber () with fuel after the main chamber injecting means () supplies the fuel; estimating means () that estimates a degree of knocking serving as indices of an intensity of the knocking and an occurrence frequency of the knocking; and fuel controlling means () that carries out, when the degree (N) of the knocking is a first predetermined value (N) or more, fuel control that reduces a sub-chamber fuel amount representing an amount of fuel supplied by the sub-chamber injecting means (). By reducing the sub-chamber fuel amount in this manner, the occurrence of knocking can be suppressed, so that the combustion state of a divided-combustion-chamber engine can be enhanced.
