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.

Opis:: Jednym z kierunków badań związanych z wpływem transportu na środowisko jest ograniczenie emisji szkodliwych składników spalin. W artykule przedstawiono wyniki przeprowadzonych badań i dokonano analizy możliwości wykorzystania paliwa JET A-1 z dodatkiem tlenowym (CH₃(OCH₂CH₂)₃OCH₃) w silniku turbinowym GTM-120, bez modyfikacji silnika oraz zestawu elektroniki sterującej pracą silnika. Przeprowadzono ocenę wpływu różnych zawartości dodatku na emisję związków szkodliwych spalin, takich jak: tlenek węgla (CO), węglowodory (HC), tlenki azotu (NO_x), dwutlenek węgla (CO₂) oraz cząstki stałe (PM).
One of the main trends in the research related to the influence of transport on the natural environment is the reduction of the exhaust emissions. The paper presents the results of investigations and analyses related to the potential for use of the JET A-1 with an oxygen additive (CH₃(OCH₂CH₂)₃OCH₃) in a GTM-120 turbine engine without a modification of the engine and the engine control unit. An evaluation has been performed of the influence of different contents of the additive on the exhaust emission of such components as: carbon monoxide (CO), hydrocarbons (HC), nitric oxides (NO_x), carbon dioxide (CO₂) and PM (PM).

Opis:: W artykule przedstawiono badania silnika GTM-120 zasilanego Jet A-1 oraz paliwem Jet A-1 z dodatkiem etanolu (C₂H₅OH). Podczas badań mierzono zawartość głównych gazowych składników spalin CO, HC, NO_x, CO₂ oraz cząstek stałych. W badaniach wykorzystano analizator SEMTECH DS oraz spektrometr EEPS. Wyniki badań poddano analizie na podstawie której określono wpływ etanolu jako dodatku do paliwa Jet A-1 na emisję związków szkodliwych spalin.
The paper presents the research on the GTM-120 engine fueled with Jet A-1 fuel and Jet A-1 fuel with the addition of ethanol (C₂H₅OH). During the tests the content of the main exhaust components in the exhaust gas was measured – CO, HC, NO_x, CO₂ and PM. In the tests the authors used a SEMTECH DS analyzer and an EEPS spectrometer. The results were subject to an analysis based on which the influence of ethanol as a fuel additive on the exhaust emissions was determined.

Opis:: Article presents the results of fuel consumption calculation during cruise compared to remaining aircraft flight phases. Based on fuel consumption, methodology of pollutants quantitative estimation emitted by turbine engines has been developed. Material provides evaluation results of aircraft CO2, CO and NOx effusion using fuel consumption data taken from aircraft Flight Data Recorder (FDR) during cruise of various aircraft types. Knowledge of the amount of aircraft emissions on high altitudes is very important for climatologists in order to understand eventual changes in the Earth atmosphere due to aviation activities. The authors would like to draw attention of the aviation professionals to the fact that aircraft fuel consumption during cruise; thereby amount of toxic content in the exhaust from the turbine engine is significantly higher especially during flights against jet stream. Thousands flights of two operators were processed using algorithms developed by authors. The article gives an example of fuel consumption and thereby CO2, CO and NOx emission estimation based on engine performance taken from their test cell results. Calculations were performed with the consideration of the factor for engines deterioration through operation time provided by its manufacturer.

Opis:: The article presents bench test results of a four-stroke, four-cylinder, naturally aspirated, DI diesel engine operating with neat JP-8 fuel (J) and its blends with Diesel fuel (D) in following proportions by volume: 90/10 (J+10D), 70/30 (J+D30), 50/ 50 (J+D50), 30/70 (J+D70), and 100% diesel fuel (DF). The purpose of the research was to analyse and compare changes occurred in the autoignition delay, combustion events, engine performance efficiency, emissions, and smoke of the exhaust when running on JP-8 fuel, jet-diesel fuel blends, and diesel fuel at a full (100%) engine load and speed of 1400 min–1 at which maximum torque occurs and rated speed of 2200 min–1. It was found that the start of injection (SOI) and the start of combustion (SOC) occurred earlier in an engine cycle and the autoignition delay decreased by 9.0% and 12.7% due to replacement of aviation JP-8 fuel with diesel fuel at a full load and the latter speeds. Maximum in-cylinder pressure was 6.8% and 4.0% higher when operating with diesel fuel, whereas brake thermal efficiency was 3.3% and 7.7% higher, and brake specific fuel consumption 2.8% and 7.0% lower when using fuel blend J+D50 compared with the respective values measured with neat JP-8 fuel. Emissions of nitric oxide (NO) and nitrogen oxides (NOx) were 13.3% and 13.1% higher from a straight diesel running at speed of 1400 min–1, and 19.0% and 19.5% higher at a higher speed of 2200 min–1. The carbon monoxide (CO) emissions and total unburned hydrocarbons (HC) decreased 2.1 times and by 12.3% when running with fuel blend J+D70 at speed of 2200 min–1 compared with those values measured with jet fuel. Smoke of the exhaust was 53.1% and 1.9% higher when using fuel blend J+D10 than that of 46.9% and 70.0% measured with jet fuel at speeds of 1400 and 2200 min–1. The engine produced 34.5% more smoke from combustion of fuel blend J+D70 at the low speed of 1400 min–1, but smoke converted to be 11.3% lower when operating at a higher speed of 2200 min–1.
