置。 The intake passage communicating with the combustion chamber of the engine is configured with a first passage having a large passage area and a second passage branching from the first passage and having a small passage area, and the intake passage is connected to the first passage with the engine. The control valve is provided with a control valve that opens and closes depending on the operating state of the injector, and at the same time, it is possible to supply fuel from an injector to the intake passage, and the amount of fuel injected from the injector is directly drawn into the combustion chamber. In an engine, the engine is equipped with a prediction setting means for predicting and setting the direct inflow of fuel that is absorbed into the intake passage, and the removal of fuel that is vaporized and inhaled from the fuel attached to the wall of the intake passage. A detection means for detecting a signal, and a changing means for changing a predicted value of at least one of the direct input portion and the removed portion according to the opening degree of the control valve detected by the detection means. Features: Engine fuel control device.
