Grey Relational

Engine performances and emission characteristics of Karanja oil methyl ester blended with diesel were carried out on a variable compression diesel engine. In order to search for the optimal process response through a limited number of experiment runs, application of Taguchi method in combination with grey relational analysis had been applied for solving a multiple response optimization problem. Using grey relational grade and signal-to-noise ratio as a performance index, a particular combination of input parameters was predicted so as to achieve optimum response characteristics. It was observed that a blend of fifty percent was most suitable for use in a diesel engine without significantly affecting the engine performance and emissions characteristics.

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 review reports the results of various researches work on the engine performance and emission characteristics of diesel engine using different nanoadditives in jojoba biodiesel - diesel blends. Blending of diesel with biodiesel in a diesel engine has gained importance, due to its economical and environmental benefits. Jojoba biodiesel gained an importance as an alternative fuel over conventional diesel fuel even with their unfavorable effects of power reduction. The wide spread usage of nanoadditives to improve the combustion quality may be a good solution of this problem. Blending of nanoparticles as an additives in biodiesel – diesel blends improves the thermophysical properties, such as thermal conductivity, mass diffusivity and high surface area-to-volume ratio. Based on the results available in the literature, it has been found that nanoadditives with jojoba biodiesel - diesel blends improve the performance of diesel engine and reduced the emission of toxic gases depending upon the dosage of the nanoadditives.
