“…The higher reductions of the peak heat release rate were observed for operation with 7.5 and 10% EGR. The biodiesel effects have not been investigated here, but, according to the literature, its presence in the diesel fuel may have caused a slight reduction in the in-cylinder peak pressure and peak heat release, especially at full load, mainly due to poor atomization and inadequate air-fuel mixing of biodiesel blends [40,41]. Figure 4 shows the intake air mass flow rate for operation with different EGR rates.…”

“…Nevertheless, it is known that in certain proportions of the two fuels (mineral diesel and biodiesel), there are significant change on engine performance and emission levels. Some studies show that the use of pure biodiesel in vehicle diesel cycle engines reduces the torque and consequently the power generated (MAZIERO et al, 2006;OZSEZEN et al, 2009;BUYUKKAYA, 2010;FIORESE et al, 2011;NIETIEDT et al, 2011) and increases the time consumption and minimum specific consumption (GODESA, et at. 2010;NIETIEDT et al, 2011;REIS et al, 2013;ÖZENER et al, 2014).…”

ABSTRACT:The use of fuels for agricultural Diesel engines cycle, both of mineral origin (Diesel) or vegetable and animal origin (biodiesel) can significantly alter its performance. Therefore, the aim of this study was to quantify the change in torque, power and consumption of agricultural Diesel engine fuel using minerals and vegetables fuels. It was used a tractor power take-off coupled to a magnetic brake dynamometer (for measuring speed and torque for subsequent calculation of power), and a flow meter (for measuring the hourly fuel consumption and specific fuel consumption calculation). Eleven different fuels (S10 mineral diesel with 5%, 10%, 15%, 20% and 50% biodiesel and mineral diesel S500 with 5%, 10%, 15%, 20% and 50% biodiesel, have been used pure biodiesel B100). The results indicate that the increase of biodiesel in mineral diesel reduces torque and power, increases the specific fuel consumption and practically does not change the hourly consumption. This reduction in torque and power occurs with greater intensity in Diesel S10. Additions of 10% biodiesel in mineral diesel reduces the maximum torque 1.65 Nm (0.6%), the maximum power at 0.33 kW (0.6%) and increases the specific fuel consumption of 3.6 g kWh -1(1.3%).

“…Ramadhas et al (2006) studied the energy balance for a diesel engine running on biodiesel and diesel fuel and found that the engine heat losses, when using biodiesel, is higher compared with diesel fuel. Buyukkaya (2010) experimentally investigated the using of pure biodiesel and biodieseldiesel blends in a diesel engine. He found that the peak pressure, peak heat release rate and ignition delay decreases by about of 5, 14 and 32% respectively, at 2000 rpm and engine full load.…”

Abstract:In general, small part of fuel chemical energy transforms to effective power in diesel engines and other parts are going as energy losses, there for many researchers, as well as engine designers, are searching to increase this part by using various methods. In this study, the effect of pure biodiesel and biodiesel-diesel fuel blends on engine energy balance, compared with diesel fuel, has been performed. For this purpose, diesel engine coupled with a dynamometer, as well as, the thermocouples (to measure the temperatures in different locations) and the flow meter (to measure the water flow rate) have been used. In addition, biodiesel mixed with diesel fuel to obtain various proportions of the fuel blends. The engine heat losses through: Cooling water system, exhaust gases and by radiation have been calculated, on the base of experimental results. The results show that an increase of the biodiesel in the fuel blends lead to increase of heat losses. Moreover, the energy distribution from the fuel used for the experiments show a decrease in useful work, increase of heat lost with cooling water, heat lost with exhaust gases and by radiation by about of (average values) 7, 3.8, 4.8 and 4.5% respectively when compared with diesel fuel. The energy distributions were as 26, 27, 22 and 0.46% for useful work, heat losses with cooling water, with exhaust gases and by radiation, respectively.
