1. A fuel injection system, comprising:
a fuel injection valve configured to inject fuel; a heater configured to receive a supply of electric power from a predetermined power source and heats fuel before the fuel is injected from the fuel injection valve; and a processor that is programmed to: estimate a temperature of the heater on a basis of a resistance value of the heater; and correct the estimated temperature of the heater so that a difference between a nucleate boiling start point temperature of the fuel and an estimated temperature value of the heater at a time of occurrence of a point of inflection in the resistance value of the heater after energization to the heater is started is reduced. |
