摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine capable of appropriately controlling an air-fuel ratio even if a valve temperature is changed. SOLUTION: The internal combustion engine 10 includes a port injection injector 20 and a cylinder injection injector 21, and an injection ratio of fuel injected from each of the injectors 20, 21 is variably set based on an engine operating state. When the fuel injection mode of each of the injectors 20, 21 is changed, the total difference in the amount of adhesion to a wall surface before and after a change in the fuel injection mode and the total difference in the valve temperature before and after the change in the fuel injection mode are calculated. When the divergence degree of the valve temperature before and after the change in the fuel injection mode is higher than a predetermined value, a variation in the valve temperature after the fuel injection mode is changed is estimated based on a total difference in the valve temperature, and the amount of fuel injected is gradually corrected based on a difference in the amount of gradual adhesion calculated based on the variation.

摘要： PROBLEM TO BE SOLVED: To provide a fuel injection control device for an internal combustion engine capable of surely compensating for the reduced amount of fuel fed into a combustion chamber by more accurately executing increase-correction of the fuel injection quantity. SOLUTION: An electronic control device sets fuel injection quantity according to an operation state of the engine, opens a fuel injection valve disposed in an intake port, and injects fuel of the fuel injection quantity and supplies the same to an inside of the combustion chamber. The electronic control device executes increase-correction of the fuel injection quantity based on a period (overlap period TOL) during which a floating period T2 during which fuel injected from the fuel injection valve floats in the intake port and a reverse flow period T1 during which burned gas in the combustion chamber reversely flows to the intake port, accompanying open of an intake valve, overlap.

摘要： PROBLEM TO BE SOLVED: To provide a control device for an internal combustion engine capable of satisfying requirement characteristics of the internal combustion engine while surely inhibiting fuel adhesion on an intake port caused by interference of reversely flowing burned gas and fuel. SOLUTION: The electronic control device changes target injection timing of a fuel injection valve and target valve timing of an intake valve to a side shortening an overlap period TOL (sides indicated by arrows A, B) respectively when it is in the overlap period TOL of a floating period T2 during which fuel injected from the fuel injection valve floats in the intake port and a reverse flow period T1 during which burned gas in the combustion chamber reversely flows to the intake port side, accompanying open of the intake valve. The target injection timing and the target valve timing are changed so that ratio of each change quantity of the target injection timing and the target valve timing to total change quantity is ratio for materializing requirement characteristics of the internal combustion engine.
