Title:
The fuel injection system of an internal-combustion engine
Document Type and Number:
Japanese Patent JP6090593
Kind Code:
B2
Abstract:
A control device for an internal combustion engine is provided. The internal combustion engine includes an in-cylinder injector (30). The control device includes an electronic control unit (50). The electronic control unit (50) is configured to: (i) control energizing time for the in-cylinder injector (30) when a partial lift injection is performed such that the partial lift injection becomes maximum partial lift injection with a longest energizing time in the partial lift injection; and (ii) control the number of energizations for performing the maximum partial lift injection during a single injection stroke such that a total of injection amounts of the maximum partial lift injection by the number of the energizations is equal to or less than a required injection amount as a target amount for the injection amount of a single injection stroke.
