LTC Fuel Quality Requirements

This article presents an analysis of legal actions taken to determine fuel quality requirements, emission standards adapted to meet global and European health and environmental protection programs, including the World Wide Fuel Charter and other relevant directives. The series of subsequent consecutive legal regulations, including more and more restrictive automotive fuel requirements, aimed at decreasing the negative impact of vehicle usage on the natural environment and human health. The results of the assessment of the implementation of the mentioned regulations in Poland are presented as well.

Microwave Losses

One of the conditions for ensuring the safety of air transport operation is the quality of aviation fuel refueled in aircraft. Fuel quality control is a multi-parameter task that includes monitoring the free moisture content. Regulatory documents establish the content of free water no more than 0.0015% by weight. It is developed a direct electrometric microwave resonance method for controlling free moisture in aviation fuels, which consists in changing the shape of the water drops by pressing them on a solid surface inside a cylindrical cavity resonator. This can dramatically increase dielectric losses. Analytical and experimental analysis of the proposed method is carried out. The control range from 0,5 to 30 μl of absolute volume of moisture in aviation fuels with a maximum error of not morethan 25 % is justified. The sensitivity of the proposed method for monitoring microwave losses in free moisture drops transformed into a thin layer by pressing is an order of magnitude greater than the sensitivity of the method for monitoring microwave losses in moisture drops on a solid surface in a resonator. The proposed method can be used as a basis for the development of devices for monitoring the free moisture of aviation fuels in the conditions of the airfield and laboratory. The direction of development of the method is shown.
