Title:
内燃機関制御装置
Document Type and Number:
Japanese Patent JP6994447
Kind Code:
B2
Abstract:
To provide an internal combustion engine control device capable of more appropriately suppressing the adhesion of injected fuel to the inner wall of an intake passage and an intake valve even when there is a need for changing over to heterogeneous-mode fuel injection control.SOLUTION: When a fuel injection control part 113 changes over fuel injection control from combination-mode fuel injection control to alternation-mode fuel injection control, an internal combustion engine control device 100 allows the start of fuel injection in the alternation-mode fuel injection control from a shorter-section-length injector which is allowed to execute the fuel injection in an exhaust stroke in the combination-mode fuel injection control during the changeover, out of an injector 13a and an injector 13b.SELECTED DRAWING: Figure 1
