Trends of Air Fuel Ratio on Engine Performance of Four Cylinder Direct Injection Hydrogen Fueled Engine

The present study focuses on the effect of air-fuel ratio on the performance of four cylinder hydrogen fueled direct injection internal combustion engine. GT-Power was utilized to develop the model for direct injection engine. Air-fuel ratio was varied from rich limit to a lean limit. The rotational...
