Fuel injection controller and fuel injection control method for internal combustion engine

A fuel injection controller for an internal combustion engine selects as the injection mode either single injection or split injection, counts, based on a drive current detection signal, which indicates that a drive current is generated to be fed to the direct injector, the number of occurrences of the drive current in one combustion cycle as a number-of-injections count value, and determines, based on the number-of-injections count value, whether the combustion state in the cylinder is satisfactory. The fuel injection controller determines that the combustion state in the cylinder is unsatisfactory if the number-of-injections count value in one combustion cycle is one when catalyst warm-up control is being performed with the temperature of the engine being lower than or equal to a predetermined temperature.. ...
