摘要： PROBLEM TO BE SOLVED: To provide a fuel property detection apparatus capable of accurately detecting the concentration of a biofuel in a mixed fuel of a hydrocarbon fuel and the biofuel despite a compact and a simple constitution and excellent in durability and reliability.
SOLUTION: A fuel property sensor 22 includes a light-emitting element 28 and a light-receiving element 32 for detecting the light transmittance of a fuel in a fuel passage 26 and a light-emitting element 36 and a position detection element 38 for detecting the refractive index of the fuel.
