“…In internal combustion engines it is desirable to convert fuel energy into engine performance at the highest rate, but conversion of all the fuel energy into work thus a one hundred percent energy conversion is not possible [1,2]. Some of the losses that occur during energy conversion are caused by irreversibilities.…”

“…In particular, considering air pollution the share of emissions caused by motor vehicles cannot be underestimated. Since the invention of the internal combustion engine many different fuel have been used such as gasoline and diesel, which are known under the name of conventional fuels, natural gas, liquefied petroleum gas (LPG), alcohols and even various alternative fuels such as biodiesel, biogas, hydrogen, and their blends in order to achieve lower fuel consumption and emissions and better engine performance [2,6]. While there are many options that can be fuels for internal combustion engines, the real issue is to determine how well a fuel serves the desired purpose [7].…”

“…Caton [13] presented an analytical study analyzing exergy destruction during the combustion process, based on the second law of thermodynamics. Tat [2] investigated the effect of cetane number and ignition delay on the energy and exergy analyses for a diesel engine run on two different biodiesels made from soybean oil methyl ester (SME) and the yellow grease methyl ester (YGME) and blends consisting of 0.75% and 1.5% of cetane improver by weight with SME. Giakoumis [14] studied the effect of cylinder wall insulation using silicon nitride and plasma spray zirconia as insulators for a turbocharged diesel engine operating under transient load conditions from both a first and second law perspective.…”

Abstract:In this study, energy and exergy analysis were performed for a single cylinder, water-cooled diesel engine using biodiesel, diesel and bioethanol blends. Each experiment was performed at twelve different engine speeds between 1000 and 3000 rev/min at intervals of 200 rev/min for four different fuel blends. The fuel blends, prepared by mixing biodiesel and diesel in different proportions fuel with 5% bioethanol, are identified as D92B3E5 (92% diesel, 3% biodiesel and 5% bioethanol), D85B10E5 (85% diesel, 10% biodiesel and 5% bioethanol), D80B15E5(80% diesel, 15% biodiesel and 5% bioethanol) and D75B20E5 (75% diesel, 20% biodiesel and 5% bioethanol). The effect of blends on energy and exergy analysis was investigated for the different engine speeds and all the results were compared with effect of D100 reference fuel. The maximum thermal efficiencies obtained were 31.42% at 1500 rev/min for D100 and 31.42%, 28.68%, 28.1%, 28% and 27.18% at 1400 rev/min, respectively, for D92B3E5, D85B10E5, D80B15E5, D75B20E5. Maximum exergetic efficiencies were also obtained as 29.38%, 26.8%, 26.33%, 26.15% and 25.38%, respectively, for the abovementioned fuels. As a result of our analyses, it was determined that D100 fuel has a slightly higher thermal and exergetic efficiency than other fuel blends and all the results are quite close to each other.

This study deals with energy and exergy analyses of a four stroke, four cylinders, naturally aspirated, direct-injected diesel engine fueled with diesel and peanut biodiesel. Energetic and exergetic performance parameters of the engine for each fuel were computed and compared with each other. The effect of varying dead state temperatures on exergetic parameters was also investigated. It is concluded that peanut biodiesel indicated similar performance with diesel fuel in terms of the energy and exergy efficiencies. Energy efficiencies of the engine fueled with diesel and peanut biodiesel were determined to be 35.26% and 34.37% while the corresponding exergy efficiencies were calculated to be 33.09% and 32.02%, respectively. The exergy efficiency values for fuels decreased from 35.39 to 31.34% with increasing the dead state temperature from 0 to 358C.
