Abstract

See full text

A cold-time fuel increasing section calculates, as increase correction values for a required injection amount, an increase-after-startup correction value, which attenuates with an increment of the number of times of combustion carried out after startup of the internal combustion engine, and a basic warmup increase correction value, which attenuates with an increase in a temperature of coolant in the internal combustion engine. The cold-time fuel increasing section calculates the increase correction values such that the increase-after-startup correction value when the port injection mode is selected is greater than the increase-after-startup correction value when the single direct injection mode is selected, and that the basic warmup increase correction value when the port injection mode is selected is less than the basic warmup increase correction value when the single direct injection mode is selected.
