The effect of biodiesel percentage in biodiesel-diesel blends on the engine under different engine operation conditions must be predicted to achieve high performance. The goal of the present paper was to model brake power, brake torque, thermal efficiency, and specific fuel consumption of a diesel engine fueled by algal biodiesel-diesel blends. The response surface methodology was successfully applied to model the performance indicators of biodiesel-diesel fueled OM 314 diesel engine at various engine loads and rotational speeds. Brake power, torque, and thermal efficiency increased by increasing engine load. Increasing engine rotational speed caused increase in brake power whereas highest brake torque and thermal efficiency was obtained in medium engine rotational speed. Increase of biodiesel percentage caused decrease in. Biodiesel had negative effects, but it had lower effects than engine load and rotational speed on the change of the engine performance indicators. Brake specific fuel consumption decreased by increasing load but it was lowest in medium rotational speeds. A quadratic model was suitably fitted to predict the effects of input-output variables with statistical significance of 1% probability level. The coefficient of determinations for prediction of the engine brake power, brake torque, thermal efficiency, and brake specific fuel consumption were 97.63, 99.74, 97.41, and 95.72%, respectively. The result of the present work is useful to find optimum biodiesel percentage and engine load and rotational speed to achieve high performance fuel blends.

During past decades, increasing energy demand across the world fueled energy production significantly, which lead to environmental impacts such as Global warming, depletion of the ozone layer, it also endangered the Species. Hence, the whole world started shifting towards green energy generation, eliminating all the negative Impacts on the environment. Solar power is the most efficient source of energy among other renewable energy sources. This article analyzes the simulated performance of a 250 kWp grid-connected Si-poly photovoltaic Plant. This study was conducted to evaluate the performance and feasibility of a Solar PV plant for Pune, India Location. Each Module has a rating of 310 Wp are connected in 65 strings with 12 panels per string. 42 String Inverters are utilized. The simulation is carried out in PVsyst 7.2 software and Meteonorm8.0 data is used. The simulation is carried out to get maximum energy production, this experiment was performed in 2 phases, one with a fixed angle throughout the year and another by adjusting the tilt angle for every month. Multiple trials were conducted to get the best angle for maximum production of electricity. And compared their parameters such as incident radiation, Performance ratio, Energy into the grid, energy output at array and losses. The optimum angles were chosen based on input Energy at the grid.
