The Impact

Purpose The purpose of this study is to present the pollutant gas produced by hydrocarbons (HC), carbon monoxide (CO) and nitrogen oxides (NOx) and the quantity of fuel burned from commercial aircraft at Ordu-Giresun International Airport, Turkey during the landing and take-off (LTO) cycles in 2017. Design/methodology/approach The flight data recorded by the General Directorate of State Airports Authority and the aircraft engine emission data from International Civil Aviation Organization (ICAO) Engine Exhaust Emission Databank were used for calculation. The aircraft and engine types used by the airlines for flight at Ordu-Giresun International Airport were determined. To evaluate the effect of taxi time on emission amounts, analysis and evaluations were made by taking different taxi times into consideration. Findings As a result of the emission analysis, the amount of fuel consumed by the aircraft were calculated as 6,551.52 t/y, and the emission amounts for CO, HC and NOx were estimated as 66.81, 4.20 and 79.97 t/y, respectively. Practical implications This study is aimed to reveal the effect and contribution of taxi time on the emitted emission at the airport during the LTO phase of the aircraft. Originality/value This study helps aviation authorities explain the importance of developing procedures that ensure the delivery of aircraft to flights in minimum time by raising awareness of the impact of taxi time on emitted emissions, and contributes to the determination of an aircraft emission inventory at Ordu-Giresun International Airport.

Abstract: There is growing interest to study the effect of blending various oxygenated additives with diesel or biodiesel fuel on engine performance and emission characteristics. This study aims to analyze the performance and exhaust emission of a four-stroke, four-cylinder diesel engine fueled with biodiesel-ethanol-diesel. Biodiesel was first produced from crude Jatropha oil, and then it was blended with ethanol and fossil diesel in different blend ratios (B10E10D80, B12.5E12.5D75, B15E15D70, B20E20D60 and B25E25D50). The engine performance and emission characteristics were studied at engine speeds ranging from 1200 to 2000 rpm. The results show that the brake specific fuel consumption increases while the brake power decreases as the percentage of biodiesel and ethanol increases in the blend. The exhaust emission analysis shows a reduction in CO2 emission and increase in NOx emission when the biodiesel -to- ethanol ratio increases in the blends, when compared with diesel as a reference fuel.

The problems of gas turbine exhaust gas sampling by presently approved methods make an optical method attractive. Because of this, the Air Force has sponsored the development of laser. Raman for exhaust emissions measurement. Laser induced Raman and fluorescent measurements were made in the exhaust of a T53-L-13A gas turbine engine with a new field-portable instrument devised specifically for gas turbine exhaust emission measurements. The gas turbine exhaust was analyzed by conventional instruments for CO, CO2, NO, NOx total hydrocarbons, smoke, and temperature, and these data were used as a comparative standard for the evaluation of the laser Raman instrument. Results thus far indicate good to excellent correlations for CO2, O2, smoke, hydrocarbons, and temperature. NO detection was not sensitive enough, but the data analysis indicates that 100 ppm or less may be detectable with instrument improvements. Further NO sensitivity is possible with continued development of the method. CO analysis was not attempted, but it is expected that CO could be detected with further research. NO2 was not attempted because theoretical and experimental laboratory analysis indicated severe interferences with CO2. Temperature profiles from laser Raman were also compared with thermocouple data in the exhaust stream, and showed agreement within the radiation error of the thermocouples. With further development, laser Raman shows a good potential for an optical method of aircraft gas turbine emission analysis.

Advanced ceramic coating technologies are commonly used as metal coatings for internal combustion engine components and aerospace application. The thermal barrier coatings are being applied to the engine components to increasing life and improve the performance of the engine. This experimental study is focused on advanced ceramic material of Zirconia stabilized with the yttrium oxide (Zirconia 80% wt and Yttia 20 % by weight) applied on the piston crown for analyzing the performance and emission characteristics of the diesel engine. By using ceramics coated piston crown, the brake thermal efficiency and specific fuel consumption were improved as compared to that of the piston without coating. Exhaust emission level of CO, UHC and NOx are also considerably reduced using advanced ceramic metal coating techniques.

This paper reports the results of the effects of CO2 in exhaust gas recirculation (EGR) on diesel combustion and emissions. The experiments were carried out on a specially designed single-cylinder diesel engine. In-cylinder measurements were obtained from the optically accessible swirl chamber using high-speed shadowgraphy, the two-colour method and laser extinction. Furthermore, in-cylinder pressure measurements from the combustion chambers were used to derive the heat release rates during combustion. Two experiments were carried out on the effects of CO2 on diesel combustion and pollutant formation. In the first series of experiments, CO2 was used to replace some of the oxygen in the intake mixture, which simulated the dilution effect of conventional EGR. This so-called replacement EGR method was characterized by the typical NOx and smoke trade-off, where NOx reduction was accomplished at the expense of exhaust smoke. In the second series of tests, CO2 was added to the intake charge so that the oxygen concentration in the combustion chamber was not affected. In this additional EGR method, CO2 was found to suppress both NOx and smoke emissions. The mechanisms of these two different EGR modes on diesel combustion and emissions were examined using the above in-cylinder measurement techniques and exhaust emission analysis.
