Performance and Emission Analysis of Corn Oil and Rice Bran Oil using Ethanol, Methanal and Sodium Hydroxide Additives

Abstract

The fuel consumption rate has been increased in our world compared to older days. Most of the fuels which we use are fossil fuel which has high emissions of greenhouse gases which leads to pollution and global warming. Fuels are getting higher price range nowadays. So, we are trying to find a better alternative fuel which will be cost efficient and less harmful to the planet. In this study we try to solve the problem by experimenting and evaluating the mixture of oils which may reduce emissions of harmful gases. In this project we are using corn oil, rice bran oil with additives and mixing them with conventional fuel i.e., diesel to convert the collected oils into a biodiesel. This process is commonly known as transesterification. The biodiesels are mixed in three different forms like B30, B40, and B50, in which B30 contains 70% of diesel and 15% of corn oil and 15% of rice bran oil. B40 contains 60% of diesel, 20% of corn oil and 20% of rice bran oil. B50 contains 50% of diesel, 25% of corn oil and 25% of rice bran oil. We are mixing these oils with diesel and other additives in three different ratios in-order to get the maximum performance and lowest emission from a diesel engine. These samples are used as an alternative to conventional diesel in a diesel engine and the engine’s performance was evaluated. The performance of the engine is evaluated by parameters which include brake thermal efficiency, volumetric efficiency, specific fuel consumption and torque. The emission parameters are also tested which includes the emission level of CO, CO2, NOX, SOX and HC. These tests are done under different load conditions varying form no load up to 10kg. The results from the three samples (B30, B40 and B50) are compared to the conventional diesel which is being used in most conditions.
