FUEL PROPERTY DETECTION DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To provide a fuel property detection device capable of detecting both an index correlated with an alcohol concentration in a fuel including alcohol and an index correlated with a fuel density, accurately with a small and simple constitution, and having excellent durability and reliability. SOLUTION: A fuel property sensor 22 is equipped with an LED 46 and a PD 48 as light emission and reception parts for detecting the alcohol concentration in the fuel. The alcohol concentration can be determined from a light transmittance of the fuel detected by the LED 46 and the PD 48. The fuel property sensor 22 is also equipped with the light emission and reception parts for detecting the density (degree of heaviness) of a hydrocarbon fuel included in the fuel. The density of the hydrocarbon fuel included in the fuel can be determined from a refractive index of the fuel detected by the light emission and reception parts. COPYRIGHT: (C)2008,JPO&INPIT
