Performance of a Small Engine Fueled by Methane Using a Simulation Tool
Climate change and increased demands for energy, tends the researchers to search for environmental friendly resources of alternative fuels that can be used in internal combustion engines. There are many types of existing alternative fuels that can be used in internal combustion engines, but the fundamental information about their combustion process is still limited. This study focus on the performance of methane fueled engines in a small spark ignition gasoline engine. The engine performance was measured on the brake torque, brake power, brake mean effective pressure (Bmep) and in-cylinder peak pressure. A Modenas Kriss 110cc gasoline engine was selected for experimentation and engine modelling. The 3D engine model was created using CATIA and the engine performance simulation was performed using GT-Suite v7.4.3. The engine performance results for the methane fueled engine were found to be lower at about 20.1% for engine torque, brake power and bmep and 12.0% for in-cylinder peak pressure when compared to the gasoline engine. From these results it can be concluded that the methane fuel can be used as an alternative fuel but it produces lower engine performance compared to a gasoline engine.
