experimental study of using additive in the pilot fuel on the performance and emission trade offs in the diesel cng methane emulated dual fuel combustion mode
Applied Thermal Engineering, 2019Co-Authors: Xiangyu Meng, Wuqiang Long, Yihui Zhou, Hua Tian, Jiangping Tian, Chia-fon LeeAbstract:Abstract In this work, diesel-n-butanol blends as the pilot fuel were studied to explore the possibility of improving the performance and emissions in the dual-fuel combustion mode with CNG, and the trade-offs among NOx, THC and CO were also discussed. The pilot fuels including B0 (pure diesel), B10 (90% diesel/10% n-butanol) and B20 (80% diesel/20% n-butanol) were compared under two engine loads. The experiments were conducted by sweeping a wide pilot fuel start of injection (SOI) timings at two CNG substitution rates for each load. For 5 bar indicated mean effective pressure (IMEP), B10CNG40 (at the 40% CNG substitution rate) reveals the highest indicated thermal efficiency (ITE) and lowest THC emissions. While it results in slightly higher NOx emission. B20CNG70 can significantly reduce the NOx emission due to better homogeneity and higher evaporation latent heat of n-butanol. The obvious trade-offs between NOx and THC, NOx and CO can be observed at the retarded pilot fuel SOI timings. For 7.5 bar IMEP, B10CNG60 and B20CNG60 can improve ITE and lower the THC emissions, while maintaining the equivalent level of NOx emission relative to the cases at the 80% CNG substitution rate. Adding n-butanol leads to the trade-off between THC and CO emissions.

analysis of four antimigraine drugs in two ternary mixtures by sweeping micellar electrokinetic chromatography with retention factor gradient effect and dynamic ph junction
Microchemical Journal, 2016Co-Authors: F Belal, Mohie Sharaf K Eldin, M M Tolba, Mohamed I Elawady, Heba ElmansiAbstract:Abstract A new, robust, and reliable sweeping-micellar electrokinetic chromatography (sweeping-MEKC) method with dynamic pH junction and retention factor gradient effect (RFGE) is developed for the simultaneous determination of four different analytes in two ternary mixtures of pharmaceutical importance. The studied analytes are drotaverine hydrochloride and caffeine combined with paracetamol (Mixture-I) or dipyrone (Mixture-II). Different experimental parameters are carefully investigated in order to achieve the highest possible resolution and sensitivity in a short analysis time. A special interest is given to the effect of sample matrix composition on the attainable enrichment efficiency with a focus on dynamic pH junction and RFGE. Up to 8 times increase in sensitivity is achieved by the modification of the sample matrix. The theoretical considerations of the underlying effects regarding the separation and the enrichment processes are thoroughly discussed. A full validation study of the developed method based on the pharmacopeial guidelines is performed. The method is successfully applied to the analysis of the studied drugs in their co-formulated or single-ingredient tablet preparations with a total run time of less than 11 min.
