“…The LHV of fuel shows the energy efficient released by combusting a particular quantity of fuel mass unit and the products are returned at 25°C, which not considers the implicit heat of water vaporization for the products of combustion. In the view of Volpato et al, (2009), the relationship between LHV and HHV is proposed as Eq. (4).…”

Pure vegetable oils have the greatest promise for alternative fuels for internal combustion engines beside the depletion of conventional petroleum resources. Among various possible options, pure vegetable oils present promising of greener air substitutes for fossil fuels. Pure vegetable oils, due to the agricultural origin, liquidity, ready availability, renewability, biodegradability are able to reduce the CO2 emissions in the atmosphere. Also, in Vietnam, pure vegetable oils such as soybean oil (SoO100), coconut oil (CO100) and sunflower oil (SuO100) are available. The paper presents the results of using heated pure vegetable oils for diesel engine D243 with power of 80 hp (58.88) kW. The results of determining the power (Ne), specific fuel consumption (SFC) and efficiency (η) are used to evaluate the performance of engine. The results show that, the engine power (Ne) is 10%-15% lower, the SFC of engine D243 using pure vegetable oils is 3%-5% higher and the η is 2.5%-6.2% lower compared to diesel oil (DO). Among the pure vegetable oils, the best performance results for D243 diesel engine are obtained from heated pure sunflower oil up to 135 o C.

Biodiesel is a renewable fuel derived from vegetable oils used in diesel engines, in any proportion with petroleum diesel, or pure. It is produced by chemical processes, usually by transesterification, in which the glycerin is removed. The objective of this study was to compare the performance of a four stroke, four cylinder diesel cycle engines using either olive (B100) biodiesel oil or diesel oil. The following parameters were analyzed: effective and reduced power, torque, specific and hourly fuel consumption, thermo-mechanical and volumetric efficiency. Analysis of variance was performed on a completely randomized design with treatments in factorial and the Tukey test applied at the level of 5%. Five rotation speeds were researched in four replications (650, 570, 490, 410, 320 and 240 rpm). The engine fed with biodiesel presented more satisfactory results for torque, reduced power and specific and hourly consumptions than that fed with fossil diesel.Index terms: Alternative fuel, energy efficiency, combustion engine. RESUMOBiodiesel é um combustível renovável derivado de óleos vegetais, usado em motores de ciclo diesel, em qualquer proporção com o diesel mineral, ou puro. É produzido por meio de processos químicos, normalmente por transesterificação, no qual é removida a glicerina. Este trabalho foi realizado com o objetivo de avaliar o desempenho de um motor de ciclo diesel quatro tempos e quatro cilindros, utilizando biodiesel de óleo de oliva (B100), em comparação ao óleo diesel. Foram analisados os parâmetros: potência efetiva e reduzida, torque, consumo específico e energético de combustível, eficiência termomecânica e volumétrica. Foi instalado um ensaio com delineamento inteiramente casualizado (DIC) em esquema fatorial, realizada análise de variância e aplicado teste de Tukey, a 5%. Foram pesquisados cinco níveis de rotação em quatro repetições (650, 570, 490, 410, 320 e 240 rpm). O motor alimentado com biodiesel de oliva apresentou torque, potencia reduzida e consumos especifico e horário com resultados mais satisfatórios que o diesel fóssil. Termos para indexação:Combustível alternativo, eficiência energética, motor de combustão.

“…In a study by VOLPATO et al (2009), the use of soybean biodiesel (B100) was considered feasible related to the lower specific and energetic consumption of this biofuel compared to diesel, even identifying losses up to 10.7% in torque and a 6.1% decrease in the reduced power with the use of B100. In that study, it was not used the mixtures investigated in this study.…”

Studies to develop renewable fuels, such as biodiesel, as substitutes for petroleum diesel have a great environmental importance. However, in order to be effectively incorporated into the energy mix, a satisfactory performance of a diesel cycle engine under the effect of this biofuel must be ensured. The objective of this study was to evaluate the specifc fuel consumption, effective power and torque of a diesel engine related to resistive loads under varying volumetric proportions of soybean biodiesel in mineral diesel oil (5% (B5), 10% (B10), 25% (B25) and 50% (B50)) under varying applied loads (1.5, 3.0, 4.5, 6.0, 7.5 and 9.0 kW). For the test, a 7.36 kW engine coupled to a 28.8 kW three-phase electric generator was used. The loads were elevated up to 9.0 kW via a three-phase resistive bench. In terms of power and torque, the performances of the B5 and B10 mixtures were not signifcantly different, whereas the B25 and B50 mixtures displayed lower performances. The B10 mixture showed better performance in terms of consumption because the remaining mixtures had similar results to those B5 mixture. For this reason, it can be a basis for encouraging anticipation of this mixture in diesel cycle engines use. Additionally, the reduction in power and torque for mixtures with higher concentration of biodiesel should not be considered signifcant front the environmental gains from the use of renewable fuels and the analyzed technical aspects.
