Control circuitry executes an increase correction control for fuel when an internal combustion engine is started. A determination process determines whether warm-up in a cylinder is completed. A direct injection mode injects fuel only from a direct injection valve when it is determined that the warm-up in the cylinder is completed. A reduction process sets an increase correction amount of fuel obtained through the increase correction control when executing the direct injection mode to be less than an increase correction amount obtained prior to the execution of the direct injection mode.

Controller for internal combustion engine, control method for internal combustion engine, and memory medium

A cooling device for an internal combustion engine is provided. The cooling device includes a first passage connected to the internal combustion engine and circulating a coolant, a second passage connected to the internal combustion engine and circulating the coolant, a heat exchanger provided on the first passage and configured such that heat exchange is performed with respect to the coolant, a first pump provided on the first passage, a second pump provided on the second passage and an electronic control unit controlling the first pump and the second pump. The electronic control unit, when a temperature of the coolant is no lower than a predetermined temperature, drives the first pump such that a flow rate of the coolant in the first passage increases as compared to when the temperature of the coolant is lower than the predetermined temperature, and performs first control of stopping the second pump.
