Abstract
A fuel injection control apparatus of an internal combustion engine, capable of controlling the amount of fuel, which is injected from a cylinder injection valve (second fuel injection valve), with high accuracy even when its amount is small, regardless of the operating state of the internal combustion engine, is provided. The fuel injection control device has a fuel pressure adjustment means which, when the injection form of the internal combustion engine is changed, adjusts the working state of a high pressure supply pump such that the amount of fuel injection from the second fuel injection valve stabilizes, before changing the working state of the high pressure supply pump in accordance with the injection form.
