This article discusses engine performance using diesel oil and biodiesel obtained from the reaction of vegetable oils with alcohol through the process of alcoholysis. Tests carried out on variations of diesel oil 100% (B0), 10% biodiesel (B10), 20% biodiesel (B20) and 30% biodiesel (B30). Engine performance testing is carried out at 1500 rpm to 4000 rpm at intervals of 500 rpm. The highest torque is obtained at 2000 rpm using B0, B10 and B20 of 310.3 Nm, 306 Nm and 308.1 Nm, respectively. The highest power is obtained at 3000 rpm using B0, B10 and B20 of 114.7 hp, 115.1 hp and 114.9 hp, respectively. The average fuel consumption with B0, B10 and B20 is 1.42 ml/s, 1.54 m/s, and 1.74 ml/s, respectively. B30 fuel cannot be tested on a vehicle due to detonation so that combustion does not occur completely and B30 fuel properties are incompatible with the vehicle being tested.

Fossil fuel crisis and depletion, environmental pollution and ever-increase in vehicle and transportation means have renewed the scientist’s interest in the world in order to look for potential alternative fuels, which are attractive such as biodiesel, bioethanol, DME and vegetable oils. Inedible vegetable oils such as coconut oil, Jatropha oil, linseed oil or animal fat are full of potential for using directly or manufacturing biodiesel. This work is carried out in order to study the four stroke diesel engine D240 performance characteristics fueled with preheated pure coconut oil (PCO), Jatropha oil methyl ester (JOME) and compare with diesel oil (DO). The test diesel engine performance such as power (Ne), torque (Me), specific fuel consumption (ge) and thermal efficiency (ηe) is determined, calculated and evaluated while using JOME, preheated PCO and compared to DO. The results show that, power (Ne), torque (Me) and thermal efficiency (ηe) while engine is fueled with JOME and PCO are lower, otherwise specific fuel consumption (ge) is higher than those of diesel fuel, the test engine performance are gained the best for JOME and PCO100.Article History: Received Dec 9, 2016; Received in revised form January 28, 2017; Accepted February 4, 2017; Available onlineHow to Cite This Article: Hoang, T.A and Le,V.

Biodiesel Blend

The combustion related properties of vegetable oils are somewhat similar to diesel oil. Neat vegetable oils or their blends with diesel, however, pose various long-term problems in compression ignition engines, e.g., poor atomization characteristics, ring-sticking, injector coking, injector deposits, injector pump failure, and lube oil dilution by crank-case polymerization. These undesirable features of vegetable oils are because of their inherent properties like high viscosity, low volatility, and polyunsaturated character. Linseed oil methyl ester (LOME) was prepared using methanol for long-term engine operations. The physical and combustion-related properties of the fuels thus developed were found to be closer to that of the diesel oil. A blend of 20 percent was selected as optimum biodiesel blend. Two similar new engines were completely disassembled and subjected to dimensioning of various vital moving parts and then subjected to long-term endurance tests on 20 percent biodiesel blend and diesel oil, respectively. After completion of the test, both the engines were again disassembled for physical inspection and wear measurement of various vital parts. The physical wear of various vital parts, injector coking, carbon deposits on piston, and ring sticking were found to be substantially lower in case of 20 percent biodiesel-fuelled engine. The lubricating oil samples drawn from both engines were subjected to atomic absorption spectroscopy for measurement of various wear metal traces present. AAS tests confirmed substantially lower wear and thus improved life for biodiesel operated engines.

Emission And Performance

This paper presents the result of investigations carried out in studying the emission and performance of diesel engine using the castor biodiesel and its blend with diesel from 0% to 40% by volume. The acid-based catalyzed transesterification system was used to produce castor biodiesel and the highest yield of 82.5% was obtained under the optimized condition. The FTIR spectrum of castor biodiesel indicates the presence of C=O and C–O functional groups, which is due to the ester compound in biodiesel. The smoke emission test revealed that B40 (biodiesel blend with 40% biodiesel and 60% diesel) had the least black smoke compared to the conventional diesel. Diesel engine performance test indicated that the specific fuel consumption of biodiesel blend was increased sufficiently when the blending ratio was optimized. Thus, the reduction in exhaust emissions and reduction in brake-specific fuel consumption made the blends of caster seed oil (B20) a suitable alternative fuel for diesel and could help in controlling air pollution.

Cost Effective Approach

The use of biofuels in vehicles becomes more advantageous than the consumption of fossil fuels, mainly because it uses renewable sources of energy. Recently there are some concerns about biodiesel sources, and hydrotreated vegetable oils (HVO) appear as a possible advanced solution. To understand the effect that the implementation of the new and old European type-approval test cycles (NEDC e WLTP) has on the results of these fuels considering pollutant emissions and fuel consumption results, a EURO V vehicle was subject to these cycles and also to engine performance evaluation tests. For this analysis, the fuels considered were: B0 (pure diesel), B7 (7% of biodiesel), B15 (15% of biodiesel), B100 (pure biodiesel), and HVO15 (15% of HVO). The findings lead to the conclusion that completely replacing fossil fuels with biofuels is not the most cost-effective approach. No significant differences were observed considering the two homologation cycles, the oldest (NEDC) and the actual (WLTP) and the use of HVO also does not present any relevant differences concerning the fuel consumption differences to B0 (+0.58% NEDC and +0.05%WLTP), comparing well with biodiesel behavior (−1.74% NEDC and −0.69%WLTP for B7 and +1.48% NEDC and 1.89% WLTP for B15). Considering the power of the engine obtained with the fuels, the differences are almost negligible, revealing variations smaller than 2% for B7, B15, and HVO15.

Considering the fuel demands, lots of researches have been done in the field of alternate fuels. After attaining the saturation level in this research area, still we are in need to find some alternate ways for fuel demand. Previous researchers concluded that approximate addition of 0-20% of vegetable oil with conventional diesel fuel leads to closer performance of diesel oil and controlled carbon emission; additionally they proved that there is no engine modifications needed for this optimized blend characteristic usage. Likewise, Chemical additives also can be added directly with diesel fuel and fuel blends of vegetable oils in which various researches concluded that 0-10% addition of chemical additives providing closer performance to diesel fuel. If we specifically pointing about solvent ether say Di-ethyl ether, resulting preferable performance to use as alternate fuel up to 0-5% and accepted results have been provided on some vegetable oils such as POME, Neem oil. In case of Jatropha oil, Proper results and Experiments are not found to be used as better alternative solution with Di-ethyl ether blend. This article brings us to enhanced experiment details and results obtained on Di-ethyl ether with Jatropha oil blend in which optimized Bio-diesel blend (J20= 80% diesel and 20% Jatropha oil) is taken as base fuel throughout the experiment. Keeping J20 oil as base fuel, experiments are conducted with various proportions of Di-ethyl ether (0-12%). Additionally it provides, engine performance characteristics and emission parameters when compared to conventional diesels, Jatropha blend (J20), Di-ethyl ether blend.

Analysis Of Performance

Abstract A comparative analysis of performance of Diesel engines fuelled by diesel oil, methyl ester of rapeseed oil and raw rapeseed oil was performed. The analysis of external characteristics of engines powered by various fuel types was accepted for an assessment. Engine performance rates were analysed while attention was paid to power courses, moment, unit fuel consumption and hour fuel consumption, exhaust fumes temperature and exhaust smoke. Operation effectiveness of engines was assessed when they were fed with various fuel types and optimal proportions of fuel mixtures were indicated. Environmental aspects of powering the engines with traditional fuels and crop-based fuels were analysed. The total CO2 emission in the entire process of manufacturing and combustion of fuels was accepted as a criterion. A simplified economic analysis was performed in the aspect of the underlying purpose of using crop-based fuels for propulsion of piston engines. Conclusions and recommendations that indicate directions of development concerning the analysed issue were prepared.
