“…Among these diesel/SVO/DEE triple blends, the greater percentage of substitution has been reached in [38,50] and, also, in the present study (40%). However, with regard to soot emission, a higher reduction of 77%, is achieved in this work, comparing to a reduction from 9.2% to 64.6% obtained with the other triple blends [37,38,50]. The blend containing biodiesel from vegetable oil instead of SVO shows lower diesel replacement and minor reduction of opacity, 22.5% and 8.1%, respectively [40].…”

“…It is important to take into account the different parameters in the engine as well as the different fuel loads that have been employed in each study. As can be seen in Table 4 and, to the best of our knowledge, literature about diesel engine fueled with diesel/DEE/oils blends is very recent and limited to a few studies belonging to M. Krishnamoorthi and A. Kumar [36][37][38]50]. Among these diesel/SVO/DEE triple blends, the greater percentage of substitution has been reached in [38,50] and, also, in the present study (40%).…”

“…Therefore, a mutual benefit can be obtained by the use of DEE with vegetable oils in triple blends with diesel, i.e., DEE reduces the high viscosity of the oils, whereas the oils could compensate for the heat and evaporation of DEE. In fact, DEE has been reported as a low-emission renewable fuel and high-quality combustion improver in blends with diesel fossil [27,28], with biodiesel [27,29,34,35], with oils [27,29] or with diesel/oil [36][37][38]. Besides, better performance of compression-ignition engines operating with DEE/diesel/biodiesel triple blends has been achieved [39,40].…”

Diethyl Ether as an Oxygenated Additive for Fossil Diesel/Vegetable Oil Blends: Evaluation of Performance and Emission Quality of Triple Blends on a Diesel Engine

The aim of this work is to analyze the effect of using diethyl ether (DEE) as an oxygenated additive of straight vegetable oils (SVOs) in triple blends with fossil diesel, to be used in current compression ignition (C.I.) engines, in order to implement the current process of replacing fossil fuels with others of a renewable nature. The use of DEE is considered taking into account the favorable properties for blending with SVO and fossil diesel, such as its very low kinematic viscosity, high oxygen content, low autoignition temperature, broad flammability limits (it works as a cold start aid for engines), and very low values of cloud and pour point. Therefore, DEE can be used as a solvent of vegetable oils to reduce the viscosity of the blends and to improve cold flow properties. Besides, DEE is considered renewable, since it can be easily obtained from bioethanol, which is produced from biomass through a dehydration process. The vegetable oils evaluated in the mixtures with DEE were castor oil, which is inedible, and sunflower oil, used as a standard reference for waste cooking oil. In order to meet European petrodiesel standard EN 590, a study of the more relevant rheological properties of biofuels obtained from the DEE/vegetable oil double blends has been performed. The incorporation of fossil diesel to these double blends gives rise to diesel/DEE/vegetable oil triple blends, which exhibited suitable rheological properties to be able to operate in conventional diesel engines. These blends have been tested in a conventional diesel engine, operating as an electricity generator. The efficiency, consumption and smoke emissions in the engine have been measured. The results reveal that a substitution of fossil diesel up to 40% by volume can be achieved, independently of the SVO employed. Moreover, a significant reduction in the emission levels of pollutants and better cold flow properties has been also obtained with all blends tested.

The present investigation emphasis on characteristics of pyrolysis products was obtained by intermediate pyrolysis of Aegle marmelos (AM) deoiled seed cake and appropriateness of engine adaptation. The superior volatile matter (73.69%) contented AM biomass was elected as the feed stock in this study. Pyrolysis experiment was done by a fixed bed reactor at 600°C and obtained 42–55% bio‐oil yield. Investigation of bio‐oil by GC/MS and FTIR established the occurrence of methyl, ester, alkanes, ketones and oxygenated chemicals have been alternates for fossil fuels. SEM and EDX analysis of bio‐char exposes activated carbon and ensured that biochar can be used in the waste water treatment plant, solid fuel, organic fertilizer, and natural mosquito destroyer. According to GC analysis, the presence of CH4, H2, and C2H6 evolved syngas in AM pyrolysis process can be used C.I engines at dual fuel mode operation. An engine test reveals that adding of the pyrolysis oil diminished BTE (%) and increasing BSEC (MJ/kWhr). However, increasing bio‐oil ratio blend with diesel reduces hazardous emissions like CO, HC, NOx, and smoke in the exhaust. Based on engine results, it was proposed that equal to 20% of AM bio‐oil can be used as a fuel substitute for diesel engines. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13116, 2019

This investigation is carried out as an effort to apply infrared thermography for assessing diesel engine life monitoring. The thermal image from engine operation is quantified via applying image processing to evaluation engine life in terms of pixel values and it is associated with engine heat release rate (HRR) and oxides of nitrogen emission (NOx). The area of cylinder head heat (CHH) from infrared image and engine life possess inverse correlation. Engine analysis was conducted on direct injection, four-stroke, and single-cylinder diesel engine with a constant speed of 1500 rpm and a standard compression ratio of 17.5:1 at varying engine load (W) conditions. The engine behavior and infrared (IR) image processing analysis resulting from Aegle marmelos pyrolysis oil-diesel opus (A20) was compared with neat diesel. Engine experimental and image processing output responses reveal that A20 fuel opus is suggested to attain the enhanced engine life as compared with diesel fuel.
