Patent ID: 8240192

Claim:
A fuel temperature sensing device applied to an internal combustion engine having injectors provided in respective cylinders for injecting fuel, which is distributed from a pressure accumulator, from injection holes, the fuel temperature sensing device comprising: a plurality of fuel temperature sensors provided to the respective cylinders for sensing fuel temperature, wherein each of the fuel temperature sensors is arranged in a position closer to the injection hole than to the pressure accumulator in a fuel passage extending from the pressure accumulator to the injection hole; an average value calculating means for calculating an average value of fuel temperature sensing values sensed with the fuel temperature sensors of the respective cylinders; a deviation calculating means for calculating deviations between the average value and the fuel temperature sensing values of the respective fuel temperature sensors; and a correcting means for correcting the fuel temperature sensing value of each of the fuel temperature sensors to approximate the deviation to zero for each of the fuel temperature sensors.
