Abstract
The invention relates to a control device applied to a cylinder injection type of the engine (). The control device carries out a fuel injection while changing a penetration force of the injected fuel by changing a maximum value of a lift amount of the valve body () of the injector (). Further, the control device controls an ignition timing on the basis of the engine operation state. The control device changes an end timing of a preceding injection carried out immediately before the ignition timing such that a time period between the end timing of the preceding injection and the ignition timing under a state where a first value is set as the maximum value of the valve body lift amount in the preceding injection, is longer than a time period between the end timing of the preceding injection and the ignition timing under a state that a second value larger than the first value is set as the maximum value of the valve body lift amount in the preceding injection.
