Abstract
A fuel temperature sensing device has fuel temperature sensors provided to respective cylinders for sensing fuel temperature. Each fuel temperature sensor is arranged in a position closer to an injection hole than to a pressure accumulator in a fuel passage extending from the pressure accumulator to the injection hole. The device has an average value calculating section for calculating an average value of fuel temperature sensing values sensed with the fuel temperature sensors of the respective cylinders. The device has a deviation calculating section for calculating deviations between the average value and the fuel temperature sensing values of the respective fuel temperature sensors. The device has a correcting section for correcting the fuel temperature sensing value of each fuel temperature sensor to approximate the deviation to zero for each fuel temperature sensor.
