Embodiment Construction

[0047] The following description is merely exemplary in nature and is not intended to limit the invention, application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0048] As those skilled in the art would realize, the described forms may be modified in various different ways, all without departing from the spirit or scope of the present invention.

[0049]Also, in the exemplary forms, since the same reference numerals denote the same elements having the same configuration, the first exemplary form is representatively described, and in the other exemplary forms, only configurations different from the first exemplary form will be described.

[0050] The figures are schematic and not shown to scale. Relative sizes and ratios of parts in the drawings are shown exaggerated or reduced in size for clarity and convenience, and the dimensions are illustrative only and not limiting. ...

Abstract

A method of analyzing fuel component using an RF (Radio Frequency) sensor for a vehicle includes: receiving a new fuel into a fuel tank so as to mix existing fuel in the fuel tank with the new fuel, measuring a resonance frequency of the mixed fuel using an RF sensor, comparing the measured resonance frequency of the mixed fuel with a resonance frequency of a standard fuel, determining whether themixed fuel is a normal fuel through the comparison, maintaining an engine combustion pattern corresponding to the standard fuel when the mixed fuel is a normal fuel, and operating reflecting an engine combustion control.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2018-0101212 filed on August 28, 2018, the entire contents of which are incorporated herein by reference. technical field [0003] The present invention relates to a method of analyzing fuel composition for vehicles using RF (Radio Frequency) sensors. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] When an RF signal passes through the material between the two antennas, there is a specific resonant frequency that minimizes the reflection coefficient (dB) according to the inherent dielectric constant of the material. All objects have an intrinsic dielectric constant. Gasoline, diesel, kerosene, heavy oil, and other automotive fuels also have intrinsic dielectric constants. Therefore, when fuel is placed between...
