Performance Evaluation of IC Engine with Dual Fuel Blend of Palm and Jatropha biodiesels
Main Article Content
Abstract
In this study, we synthesise and blend two different biofuels of variable percentages to examine their overall efficiency and emissions. Tests were done on Variable Compression Ratio (VCR) diesel engines at a constant speed of 1500 rpm with varying loads and compression ratios to measure their efficiency. In comparison to diesel, D90PB5JB5 shown to enhance Brake Power (BP) by 1.5% during testing. Both the D80JB10PB10 test fuel and the D90JB5PB5 fuel had Brake Specific Fuel Consumption (BSFC) that were somewhat higher than those of normal diesel, but the BSFC of both fuels were identical to those of fossil diesel. The D90JB5PB5 biodiesel mixture provides the best thermal braking performance, while the D80JB10PB10 diesel mixture falls short. When using dual biological diesel fuel, the engine produces fewer carbon monoxide and hydrocarbon emissions than it did when using regular diesel fuel.
