Abstract

Fuel adulteration involving the illicit mixing of substances such as kerosene and diesel with petrol poses significant risks to engine performance, environmental safety and consumer health. This paper presents a novel HC-PCF sensor designed to accurately detect and identify adulterants in petroleum-based fuels with unprecedented sensitivity and selectivity. The proposed HC-PCF sensor features a unique circular core structure surrounded by a carefully engineered square cladding region, enabling highly sensitive detection of refractive index changes caused by the presence of adulterants. Through rigorous numerical simulations and optimisation, our design achieves remarkable maximum relative sensitivities of 98.56%, 98.95%, and 99.32% for petrol, kerosene, and diesel, respectively, outperforming many previously reported techniques. A comprehensive analysis of the sensor's performance reveals an ultra-low confinement loss of 4.08 × 10−10 dB/m, 1.08 × 10−13 dB/m, and 2.95 × 10−12 dB/m and effective material loss of 0.0040 cm−1, 0.0036 cm−1, and 0.0034 cm−1, highlighting its exceptional light-guiding capabilities and sensitivity. The sensor's high responsiveness facilitates the detection of even trace levels of adulterants by capturing minute refractive index variations as low as possible, enabling real-time monitoring and timely intervention in adulteration incidents. The proposed HC-PCF sensor exhibits high selectivity, precisely targeting the refractive index signatures of fuels, ensuring accurate detection even in complex chemical environments. Its compact size and robust design make it suitable for deployment in various fuel quality control applications, from transportation to industrial settings. Overall, this work introduces cutting-edge HC-PCF sensor technology that addresses the critical need for reliable fuel adulteration detection with unparalleled sensitivity and selectivity, contributing to enhanced product quality, consumer protection, and environmental sustainability in the energy sector.

使用超灵敏的hc -光子晶体光纤传感器进行痕量燃料污染物检测
燃油掺假涉及煤油和柴油等物质与汽油的非法混合,对发动机性能、环境安全和消费者健康构成重大风险。本文介绍了一种新型的HC-PCF传感器,该传感器具有前所未有的灵敏度和选择性,可以准确地检测和识别石油基燃料中的掺假物。提出的HC-PCF传感器具有独特的圆形核心结构,周围是精心设计的方形包层区域,能够高度灵敏地检测由掺假物引起的折射率变化。通过严格的数值模拟和优化,我们的设计对汽油、煤油和柴油的最大相对灵敏度分别达到了98.56%、98.95%和99.32%,优于许多先前报道的技术。对传感器性能的综合分析表明,该传感器的约束损耗为4.08 × 10−10 dB/m, 1.08 × 10−13 dB/m和2.95 × 10−12 dB/m,有效材料损耗为0.0040 cm−1,0.0036 cm−1和0.0034 cm−1,突出了其卓越的导光能力和灵敏度。该传感器的高响应性有助于通过捕获尽可能低的微小折射率变化来检测甚至痕量的掺假,从而实现实时监控和及时干预掺假事件。所提出的HC-PCF传感器具有高选择性,精确地针对燃料的折射率特征,即使在复杂的化学环境中也能确保准确的检测。其紧凑的尺寸和坚固的设计使其适用于各种燃料质量控制应用,从运输到工业环境。总的来说,这项工作引入了尖端的HC-PCF传感器技术,以无与伦比的灵敏度和选择性解决了可靠的燃料掺假检测的关键需求,有助于提高能源部门的产品质量,消费者保护和环境可持续性。
