Abstract
When a state where a lowered amount of a detection value of high-pressure side fuel pressure with respect to target fuel pressure is at least equal to a specified lowering determination value at least continues for a specified lowering determination time, a pump high-temperature determination is set 'ON'. In the case where the pump high-temperature determination is set 'ON', boost control for increasing pressure of fuel that is supplied from a feed pump to a high-pressure pump (a set value of feed pressure) from a low-pressure set value to a high-pressure set value is executed.
