Simulation Analysis on the Performance of a Hydrogen Port Fuel Injection Engine

Over the past few years, many researchers have conducted experimental and simulation studies using alternative fuels for internal combustion engines. Selected fuels should contain less or no carbon products from combustion process and eventually decrease the primary energy usage. Hydrogen has been taken into consideration. Previous researchers found that hydrogen can be used in spark ignition internal combustion engines. However, the optimum performance of an engine could not be achieved due to some limitations in regards the configurations of the air fuel ratio and compression ratio. In this work hydrogen fuel was tested in a single cylinder port fuel injection engine as the preliminary study in optimizing the engine performance. The engine performance study was based on the brake torque, brake power, brake mean effective pressure (Bmep) and peak pressure. The engine model was developed based on the Modenas Kriss 110 cc 4-stroke single cylinder gasoline engine. The CATIA software was used in developing the 3D engine model and followed by utilization of GT-Suite software in analyzing the engine performance. From the analysis, it was found that the performance of the hydrogen fueled engine is lower compared to the gasoline engine.
