<p>PROBLEM TO BE SOLVED: To solve problems for example, there are methods for determination of fuel, for example, an ultraviolet fluorescence method, a sulfur concentration analysis method, and a refraction index measurement method, but a sulfur concentration meter is expensive and a measurement method thereof is difficult, and a coumarin detection device is inexpensive, but it requires fractionation and extraction work by a solvent, and it requires long determination time, and when a coumarin removal agent is added, correct determination is impossible, and in measurement by a refraction meter, it requires labor and time for measurement, and it is impossible to determine a mixed fuel of light oil and A heavy oil, and light oil and lamp oil, and in a method for determining based on a hue value of the fuel, there is a range of error determination.SOLUTION: Fuel determination is performed by combining attribute value detection of the fuel and light adsorption intensity detection of an ultraviolet in the vicinity of 400 nm of wavelength, for enhancing determination accuracy. A fuel determination device comprising: a detection part having a color determination sensor and a light source; and an ultraviolet light adsorption intensity determination sensor and a light source; a detection result determination part; and a determination result transmission part, is installed in a fuel circuit in the vehicle.</p> |
