Experimental Study of Performance and Emissions of Fusel Oil-Diesel Blend in a Single Cylinder Diesel Engine

Abstract

Abstract-In order to reduce the dependency on fossil oil energy resources, the using of several energy resources in compression-ignition engine has been the target of attention of researchers. The major renewable alternative combustible species are methanol, biogas, ethanol, biodiesel, and hydrogen. Fusel oil is a by-product of bioethanol production during the fermentation process present one of the new alternative fuels for compression-ignition engine. The aim of this work is to experimentally investigate the effect of fusel oil -diesel blending on performance and emission in single cylinder compression ignition engines. The test achieved under 25 % engine load at five-engine speed 1200 to 2400 rpm with intervals of 300 rpm. The experimental results revealed that the engine indicted power and torque slightly decrease for F 2 0 compared with pure diesel, and the increment was happened in fuel consumption. Although diesel fuel yields, the highest volumetric efficiency and exhaust temperature. Moreover, the results showed CO 2 and CO were increased while the NOx emissions decrease with the use F 2 0. All the negative effects that happened in power and torque was because of the water content, low heating value, low cetane number for fusel oil.Index Terms-Fusel oil, NOx emissions, single cylinder engine, alternative fuels, engine performance.I.

Production of first and second-generation biodiesel for diesel engine operation: A review

“…It is challenging to employ agricultural food crops for the manufacture of biofuels because of the trend toward rising demand for edible oils. There are various crops that could be used as industrial crops on underutilized land to produce biodiesel [27]. According to the European Academies' Science Advisory Council report, biodiesels are classified into four generations.…”

“…On the other hand, biodiesel-powered diesel engines were shown to have significantly greater levels of NOx emissions and significantly reduced levels of engine performance [22]- [24]. In general, the majority of research have come to the conclusion that a mixture of biodiesel and diesel fuel ranging from 5 percent to 20 percent volume may meet all of the demands placed on the engine without requiring any engine change [25]- [27]. Furthermore, researchers discovered an upward trend in NOx emissions as well as brake specific fuel consumption (BSFC) [28], as well as a lower brake thermal efficiency (BTE) [29] for biodiesel-based fuels as compared to diesel fuel when used in diesel engines.…”
