One-dimensional numerical simulations of single-cylinder spark ignition engine fuelled H2O based emulsion fuel, methanol blends, and gasoline conventional

Abstract

In this work, we have used two types of renewable fuels for testing in one-dimensional simulation software and comparing its performance and emission characteristics with 100% Gasoline fuel. For this work, we have used ethanol 20%-H2O 2%, and gasoline 90% based micro-emulsion fuel and blends of 20% Methanol in 80% Gasoline fuel as an Alternative fuel. This work is done computationally on one-dimensional licensed AVL Boost Simulation Software. The micro-emulsion fuel was prepared in the lab by adding ethanol as co-surfactant and H2O as an additive in the blended fuel. The other alternative fuel Methanol blended 20% with Gasoline 80% is also used to test the performance and emission characteristics of multi-cylinder Spark Ignition Engine. This is a novel based work done to improve the performance and Emissions of 3- Cylinder Spark Ignition Engine. The performance parameters like power, Torque, BSFC, BMEP, showed better results & emissions like CO, HC, & NOx showed significant decrease as compared to conventional 100% Gasoline fuel. Micro-emulsion fuel were better in emissions particularly NOx, which showed 25% decreases than Methanol fuel. Also showed slightly better power & Torque output by 10% than Methanol blend. Both the renewable fuel were compared with gasoline 100%.
