Numerical 1-D Simulations on Single-Cylinder Stationary Spark Ignition Engine using Micro-Emulsions, Gasoline, and Hydrogen in Dual Fuel Mode

Abstract

This work is contributing towards reducing the emissions from stationary spark ignition engine single cylinder by adopting the state of the Art Technology Hydrogen fuel and H2O based Emulsion fuel in dual fuel mode. In addition, comparing its combustion, emissions, and performance with conventional 100% Gasoline fuel. This research work has been done on 1-D AVL Boost Simulation Software by using the single cylinder engine model setup. The main objectives of this research work is to comply with the strict emission rules Euro VII. This work predicted the overall combustion parameters, NOx, CO, and HC emissions, as well as several performance measures like power, torque, BSFC, and BMEP of stationary spark ignition engine test rig. Since Hydrogen is, zero carbon emission based fuel, so it is not creating any carbon-based emissions and has shown to be the most efficient source of energy. Although Hydrogen fuel showed no carbon emissions, but NOx emissions were slightly higher than micro-emulsion fuel. Since Hydrogen fuel burns at very high temperature, so it produced slightly more NOx emissions. The NOx emissions were 20% higher than emulsion fuel and 10% higher than Gasoline 100% fuel. The H2O based emulsion fuel is also investigated which helped in reducing the emissions and improved the performance of single-cylinder stationary spark Gasoline+ Micro-Emulsion +Hydrogen fuel Lower CO, HC, and NOx Emissions Improved Power, Torque, Bsfc, & Pressure Constant Speed & variable Load ignition test rig. The Brake power, BSFC, BMEP & Torque were also investigated power and showed greater improvement for emulsion fuel. At 60% load the Hydrogen fuel showed 50% increase in power as compared to emulsion fuel and 38% more power than Gasoline fuel. Exhaust emissions CO, HC, were compared for gasoline and emulsion fuel. The CO emissions are 18% lower for micro-emulsion as compared to Gasoline 100%, and HC emissions are 12.5% lower than gasoline 100% fuel at 20% load.
