Paper type: Essay

Oxygen variation with load in the exhaust gas for HCP micro algae biodiesel and its blends is shown in Figure –It is observed that in the exhaust gas of the engine fueled with biodiesel and its blends, O2 content slightly higher than that of diesel. The O2 content in exhaust for HCP B-100 increased by 13.07 % and 11.81 % compared to diesel at the engine load of 14.25 Kg and 17.75 Kg kg respectively. HCP B-20 showed an increase in O2 content in the exhaust by 11.54 % and 8.18 % at the engine load of 14.25 Kg and 17.75 Kg respectively compared to diesel.Exhaust gas temperature variation with Load

Figure 7. compares the exhaust gas temperature with Load for HCP microalgae biodiesel and its blends used in diesel engine. The Exhaust gas temperature of HCP biodiesel combustion is slightly lower than the PD and it is similar to the variation of PD , this indicates similar combustion profile and similar heat loss from the engine. The HCP B-100 showed a reduction of 12.23 % and 13.22 % in exhaust gas temperature (C0) compared to that of D-100 at part load of 14.25 Kg and at the maximum load of 17.75 Kg respectively. HCP B-20 showed a decrease in exhaust gas temperature by 11.51 % and 11.93 % at the engine load of 14.25 Kg and 17.75 Kg respectively compared to PD. This is due to the presence of more oxygen content in the microalgae biodiesel compared to pure diesel, which accelerate the reaction rates and the flame propagates throughout air fuel mixture resulting in improved combustion. This finding is consistent with S H. Al-lwayzy et,all, (2014).Brake Specific Fuel Consumption

Figure — shows the comparative results of the brake specific fuel consumption for diesel, biodiesel and its blends. It is observed that BSFC of HCP microalgae biodiesel and its blends are higher than that of diesel over entire range of load. From the diagram observed that at the engine load of 14.25 kg the HCP B-100 showed an increase of 15.49 % and at the load of 17.75 Kg HCP B-100 showed an increase of 15.96 Kg in Brake Specific Fuel Consumption compared to PD. HCP B-20 showed an increase of 9.85 % and 12.04 % at the load of 14.25 Kg and 17.75 Kg respectively. It is observed that increase in the amount of HCP microalgae biodiesel in the blend decreases heat value of the blends. More fuel is consumed in order to maintain the same brake power. Hence, BSFC will increase for higher percentage of biodiesel in the blend.

Figure – shows Brake thermal efficiency variation of the engine fueled with various blends of HCP Biodiesel and diesel .The fuel ability to convert its energy content into power output is measured in terms of Brake thermal efficiency of the engine. Below figure shows, BTE increases with increasing load for all fuel blends. It is observed that at the engine load of 17.75 kg the HCP B-100 showed a reduction of 3.15 % in Brake Thermal efficiency compared to D-100 and 3.0 % at part load of 14.25 Kg. HCP B-20 showed a reduction of 1.8 % and 1.4 % at max load of 17.75 kg at part load of 14.25 Kg. respectively. The other blends lie between B-20 and D-100. This is due to lower energy content, higher density and higher viscosity of biodiesel and its blends than that of diesel.At the maximum engine load of 17.75 Kg the HCP B-100 showed a reduction of 2.85 % in BP compared to D-100 as shown in the fig 3. and also at the part load of 14.25 Kg the HCP B-100 showed a reduction of 2.47 % in BP compared to D-100. HCP B-20 showed a reduction of 1.83 % and 1.48 % at max load of 17.75 kg at part load of 14.25 Kg. respectively. The other blends lie between B-20 and D-100. As expected reduction in Brake Power is due to lower calorific value of HCP B-100 compared to diesel. Lower calorific value of biodiesel leads to lower engine output in turn lower brake power compared to diesel.
