Opis:
The aim of this article is presentation of the new method of preliminary evaluation of biocomponents influence on the process of biofuels combustion in aviation turbine engines. This method is based on the tests of evaluated biofuels on engine stand MiniJetRig equipped with small turbine engine. The idea of this new method is to compare the combustion process of evaluated biofuel with the combustion of reference fuels. The reference fuel used in presented research was mineral Jet A1. Two compositions of pure hydrocarbons were blended with Jet A1 fuel and tested using MiniJetRig. The main criterion of combustion process assessment was CO concentration in exhaust gases. As the final criterion of evaluated biofuel the ΔCO = [COWx – COJet] was adopted, where COWx – the concentration of CO in exhaust gases emitted during combustion of evaluated fuel and COJet – the concentration of CO in exhaust gases emitted during combustion of Jet A1 fuel. This method was preliminary verified using HEFA biofuel previously accepted for aviation application. The obtained results qualify this biofuel as similar to Jet A1 ones – the DCO was within limits –30 – +20. The presented method needs further research, using much more evaluated fuels, to confirm their usefulness for laboratory pre-selection of new biofuels.

Opis:
Biofuel use is one of the basic strategies to reduce the negative impact of aviation on the environment. Over the past two decades, a number of biofuels produced from plants, lubricants and maintenance products have been developed and introduced. New fuels must have specific physicochemical parameters and meet stringent standards. his article presents a comparative analysis of the exhaust emissions measurement results from jet engines powered by traditional aviation kerosene and its blends with ATJ (Alcohol to Jet) biofuel. The concentrations of carbon dioxide, carbon monoxide and hydrocarbons were measured. Measurements were conducted in laboratory conditions for various engine load values. Based on the analysis, it was found that the use of biofuel increases the concentration of carbon monoxide and hydrocarbons in the exhaust gas relative to aviation kerosene. The use of biofuel did not result in an increase in fuel consumption and related carbon dioxide emissions. Based on the conducted research, it was found that biofuel use did not affect the ecological properties of the engine significantly. In addition, a correlation analysis of the measurement results from both engines was carried out.
