Performance Analysis of Diesel Engine using Copper Oxide Nano Additive

This experimental study focuses on investigation of performance and utterance attributes of a normal diesel engine with biodiesel prepared from pongamia. This study aims to reduce the emission of nitrogen oxide by adding an oxidation inhibitor Tert-Butylhydroquinone (TBHQ). The analysis for each sample is to be carried out in compression ignition engine (standard diesel engine). The engine is tested with standard diesel, pongamia methyl ester biodiesel without any additives. Then the analysis is to be carried by adding nano additive copper oxide for about 50 ppm in the above mentioned fuels. From this the best combination is found out and test is again carried out by adding the oxidation inhibitor.

Performance Analysis of Pongamia Biodiesel as an Alternative Fuel for CI Engine

India is a fastest growing major economy in 2018, with a growth rate of 7.4 per cent GDP. Energy use in developing countries like India has risen more than fourfold over the past three decades and is expected to continue increasing rapidly in the future. Energy is essential for a economical growth of any county. Biofuels derived from renewable resources will become a alternative supplement for the conventional energy sources in meeting the increasing requirements for transportation fuels. In the present paper, effort are made to evaluate the pongamia biodiesel of 20% Blend (PB20) with neat diesel as an alternative fuel for CI engine. The pongamia oil is converted into pongamia methyl esters (Biodiesel) using two step process Esterification and Transesterification. The fuel properties of raw pongamia methyl ester and blend (PB20) are evaluated as per ASTM/BIS standards to check their feasibility as an alternative fuel. The prepared blend is used to run the computerized CRDI diesel engine at different load conditions. From the experimental investigation made, PB20 has a potential to be as an alternative fuel for diesel engine. The performance of PB20 with respect to Brake Thermal Efficiency (BTHE), Mechanical Efficiency, Brake Mean Effective Pressure (BMEP) and Specific Fuel Consumption (SFC) is comparatively low when compared to neat diesel. The P-Ɵ and P-V diagram shows that the combustion of PB20 is as similar to that of neat diesel.

Load and Emission Characteristics of Pongamia Pinnata Oil in ACI Engine

As the world is running on fossil fuels there has been an ever increase in the depletion rate of these fuels. A promising and a best alternate to the fossil fuel is vegetable oils. Pongamia Pinnata oil is non edible in nature and is available abundantly in India. An experimental investigation is made to evaluate the performance, emission and combustion characteristics on a compression ignition engine by using methyl ester of pongamia with mineral diesel in different proportions. Pongamia methyl ester was blended with diesel in proportions of 50% and 100% by mass and the results are tabulated and evaluated under various test conditions. The performance parameters were found to be very close to that of mineral diesel. The brake thermal efficiency and mechanical efficiency were better than mineral diesel for some specific blending ratios under certain loads. The Efficiency and emission characteristics were also studied and levels of carbon dioxide, carbon monoxide, nitric oxide and hydrocarbons were found to be equal than pure diesel.
